Zach Eflin made one mistake pitch, and it wasn’t egregious. Gunnar Henderson corrected it with one swing.

Henderson lined a two-run homer onto the flag court in right field in the fourth inning to give the Orioles a lead, Cedric Mullins padded it in the fifth, and Eflin registered another quality start with his new team in a 5-1 victory over the Red Sox before an announced crowd of 25,445 at Camden Yards.

The Orioles are 72-50 overall, 6-1 against the Red Sox and 20-35 when the opponent scores first. They moved into a first-place tie with the idle Yankees.

Eflin was removed after 87 pitches and only one run allowed in six innings with a season-high eight strikeouts. He’s made four starts since the Orioles traded for him and all are quality by definition, with six total runs allowed in 25 1/3 innings. The four wins in his first four Orioles starts without a relief appearance are a club record, breaking a tie with Kyle Gibson in 2023.

The 12 starts without a walk this season are most in the majors.

Zach Eflin makes his fourth Orioles start tonight to kick off a four-game series against the Red Sox.

Eflin is 3-0 with a 2.33 ERA since joining the Orioles. He’s allowed five runs in 19 1/3 innings.

In his only start against the Red Sox this season, Eflin allowed three runs and six hits over five innings at Fenway Park. He’s faced them five times and gone 2-0 with a 6.00 ERA and 1.417 WHIP in 24 innings.

Rafael Devers is 6-for-13 with three doubles and two home runs against Eflin. Dominic Smith is 7-for-21 with four doubles.

Eflin and Kyle Gibson are the only Orioles to win their first three starts with their new team in their first three appearances, per STATS. Ben McDonald won his first five starts beginning July 21, 1990 after 12 relief appearances.

The Orioles are home tonight for the first time since July 31, one day past the trade deadline. They split four games in Cleveland, lost two of three in Toronto and won two of three in St. Petersburg, Fla., though the finale made it appear much worse. Strange how that works. Win a series and eat and dress in a quiet clubhouse.

The roster has changed. The knack for handling adversity, whether injuries or performance based, is the same. Let’s see how far that goes.  

Let’s also hit the pause button again coming out of the off-day and collect some thoughts.

* The Craig Kimbrel reset lasted longer than expected.

It’s still happening.

Of the six Orioles that joined the team during the deals leading up to the trade deadline, we can pretty much say that four of them are doing well thus far. One is trending up and one is trying to stay out of O’s fans' doghouse.

The struggling new Oriole is obviously lefty reliever Gregory Soto. In his first four O’s appearances, he gave up nine hits, eight runs, one homer and three walks in just 2 1/3 innings. He allowed nine hits in 15 at-bats with an ERA of 30.86.

But the Orioles are obviously not going to bail on him after four outings. Soto was an All-Star in both 2021 and 2022 with Detroit and had a 48 percent whiff rate on his slider when they acquired him. The O’s need to get that pitch going to complement his high-90s fastball.

The O’s acquired Eloy Jiménez from the White Sox and some fans wondered why with his injury history and .642 OPS this year. But he came as a player that had produced a .790 career OPS and a Silver Slugger Award in 2020.

Then Jiménez went 11-for-21 through Friday night, batting .524 with an OPS of 1.143. He did not play in Saturday's win, so he maintains those lofty stats heading into today as an Oriole.

After right-hander Zach Eflin pitched the Orioles past the Rays with a 4-1 win Friday night, the O's will look for another victory tonight. If they get it they will have another American League East series win.

Colton Cowser led off Friday's affair with his 18th homer in the first. Cowser has homered in back-to-back games and he's hit four longballs his last 11 games. Cedric Mullins hit the O's second solo shot of the night, his 12th in the sixth inning. 

The Orioles are 7-1 this season against the Rays and 5-0 at the Trop where they have outscored the Tampa 29-8. Baltimore is 15-5 its last 20 games against Tampa Bay and 24-13 in the last 37.

The O's are now 25-12 versus AL East opponents and 13-5 in AL East road games.

The Orioles send ace righty Corbin Burnes (12-4, 2.63 ERA) to the mound tonight in Game 2 of this three-game series.

ST. PETERSBURG, Fla. – Grayson Rodriguez will be shut down for at least 10 days and undergo more imaging on his right shoulder in about three weeks after receiving the diagnosis of a strain that executive vice president/general manager Mike Elias described today as “pretty mild.”

Elias met with local media in the visiting dugout at Tropicana Field and provided an update on Rodriguez, who’s the No. 2 starter in the rotation with a 13-4 record, 3.86 ERA and 1.243 WHIP in 20 games.

Rodriguez was scratched from Tuesday night’s start in Toronto after experiencing discomfort in his right lat/teres while warming in the outfield. Albert Suárez replaced him and tossed five scoreless innings.

The immediate concern centered on the possibility of a similar absence to 2022 with Triple-A Norfolk. Rodriguez missed three months with a lat/teres strain, ruining the Orioles’ plans to promote him.

His current injury isn’t as serious and he’s expected back in the rotation by late September. The discomfort is centered more in the region of the teres major muscle but also involves his lat.

If it seems like the Orioles don’t issue many intentional walks, they don’t and the stats back that up.

Heading into the Tampa Bay series, the O’s pitchers have issued just seven intentional walks this season. Only three American League teams issued less, five by New York, four by Cleveland and two by Houston. Only six major league clubs have issued less than the O’s in 2024.

Oakland pitchers lead the AL with 26 intentional walks with Boston next at 22, Toronto 21 and Texas 20.

The O’s philosophy seems to be pitch the big boppers carefully and work the edges of and off the plate. And if you walk him you walk him.

During the Toronto series, I asked manager Brandon Hyde about a specific instance during Wednesday’s game with Vladimir Guerrero Jr. but also in general how the club handles such situations when a big hitter is up.

ST. PETERSBURG, Fla. – Coral Springs native Coby Mayo received only six ticket requests for his first major league game in his home state. His parents, two brothers and some friends comprised his most intimate cheering section last night.

They didn’t get to watch him play.

Mayo sat for the second straight game, but tonight offers the possibility of his fifth start and sixth appearance.

Orioles manager Brandon Hyde won’t bury Mayo on the bench and he won’t write the rookie’s name on every lineup card. Hyde is searching for favorable matchups at the plate and third base.

Mayo is searching for his first hit. He’s 0-for-13 with two walks, both in his debut in Cleveland – and eight strikeouts. He’s simply the latest highly-rated prospect in the organization to make an entrance and stumble. Some of them figure it out without going back down and others, like Jackson Holliday this year and Colton Cowser in 2023, need a reset.

ST. PETERSBURG, Fla. – Zach Eflin didn’t receive a prolonged ovation as he walked out of the visiting dugout tonight at Tropicana Field. Rays fans didn’t get sentimental. They didn’t blow the roof off the joint in tribute to the guy they used to cheer. All they had to offer was a smattering of boos and then silence.

Eflin preferred to keep them quiet anyway, tossing seven shutout innings in the Orioles’ 4-1 victory over the Rays before an announced crowd of 20,673 inflated by a “flappy boi” zip-up hoodie giveaway.

The veteran right-hander was stingy, with only four hits allowed, one walk and seven strikeouts that tied his season high. He’s made three starts with the Orioles and they’ve been quality, with a combined five runs in 19 1/3 innings.

His seven innings tonight also matched his season high.

"That’s so good right there," said manager Brandon Hyde. "A little extra motivation pitching against a team that you were just with, and he’s made three outstanding starts for us. That was textbook pitching. He was ahead in the count, great sinker-cutter, changeup. He just really knows how to pitch and he was locating well all night."

CLEVELAND – The standings and lineup didn’t look right.

A Yankees victory earlier in the day dropped the Orioles into second place in the division. Manager Brandon Hyde attacked Guardians left-hander Joey Cantillo by giving Austin Slater and Eloy Jiménez their first starts since the trade deadline. Slater led off, bumping Colton Cowser down to seventh.

Hyde was hoping that Slater could give his club “a little spark” and might “get us going.”

Slater doubled into the left field corner in the first inning and reached on a bunt single in the fifth. Jiménez lined a run-scoring single into left field in the fourth and singled to begin the sixth.

The newcomers left their mark, including starter Zach Eflin, who posted another quality start. But Hyde also knew when to turn to the holdovers. Pick specific players for matchups and push the right buttons.

The immediate takeaway from the Orioles’ work at the trade deadline is how they went hard after quantity and also feel like they improved the quality of their rotation and bullpen and the depth of their right-handed hitters.

They really didn't skimp on the quantity.

They were as busy adding players as the Marlins were subtracting them. The flurry over the last 15-20 minutes made the evening a blur. Blizzard conditions in 90-degree heat.

The Orioles didn’t get overly aggressive and go for the trade kill, keeping top prospects who would have netted an elite starter. And I’ll say again that they weren’t dealing those guys, no matter how many rumors swirled and reports surfaced about aggressive pursuits.

How aggressive are talks if they don’t include Jackson Holliday, Coby Mayo, Samuel Basallo or Colton Cowser?

Orioles rookie Heston Kjerstad was a part of the Triple-A Norfolk team last year that ended up winning the Triple-A championship. He was with the Orioles when the Tides won that title in late September, but the lineup that night for the Tides included infielder Connor Norby and outfielder Kyle Stowers, who were traded today to the Marlins for lefty pitcher Trevor Rogers.

That lineup also included Jackson Holliday, Colton Cowser, Coby Mayo and Joey Ortiz.

It's easy to see how that team won a title.

Today Kjerstad is still an Oriole, but the other two are not.

“Norby and Stowers have been awesome. Not only great friends to me but great baseball players,” Kjerstad said this afternoon in the Baltimore clubhouse. “They’re going to go on and have great big league careers. They’ve been fun to watch play.

Right-hander Zach Eflin started for the Orioles in Game 1 yesterday. He threw well and got the win against Toronto in his O's debut. He also did something unusual for him. He fanned seven batters to tie a season-high and had six strikeouts after just four innings.

Thirteen times this year in his 20 starts, Eflin fanned five or fewer. He's mostly a control artist and a pitch-to-contact guy.

He is much more of that style pitcher then one with a premium fastball and a big strikeout rate.

Eflin can be a strikeout pitcher. And last year when his ERA was 3.50 and he finished sixth for the AL Cy Young award, he averaged 9.4 strikeouts per every nine innings. But the year before, in 2022, he averaged 7.7 K/9 and this year his average is 7.1 K/9.

There was a day in this game when 7.1 strikeouts per 9 was a lot. For instance, Jim Palmer for his career averaged 5.0 strikeouts per nine and yet won three Cy Young Awards. Today 7.1 per nine is below average.

Zach Eflin will pitch in front of much larger crowds and with a lot more at stake. He won't always watch his battery mate bleed at home plate and refuse to leave. Today’s debut with the Orioles unfolded in the mid-afternoon opener of a doubleheader, a makeup from the May 14 rainout. Empty seats were spread at every level throughout the ballpark.

The start still seemed like a big deal. The scene just didn’t match it.

Eflin allowed three runs over six innings and equaled his season high with seven strikeouts, Anthony Santander hit his 30^th homer, and the Orioles took everything the Blue Jays gave them in an 11-5 win at Camden Yards in a game that will be remembered more for James McCann’s toughness than the right-hander’s first outing with his new team.

The veteran pitcher liked his results overall and loved his catcher.

Eflin carried a shutout bid into the fifth and surrendered a three-run homer to Addison Barger, the rookie’s first in the majors. Barger entered the game after the Blue Jays removed Justin Turner and traded him to the Mariners. Just some of the weirdness from today.

Zach Eflin wasn’t ignorant to the trade rumors. He heard and read them. His soon-to-be former club kept him informed.

Eflin was in the know and on a flight to Baltimore.

This morning’s media clubhouse access allowed for introductions as Eflin stood in front of the locker that belonged to injured pitcher John Means. He already met his new teammates and threw a bullpen session. He expects to start Game 1 of Monday’s doubleheader against the Blue Jays at Camden Yards.

“Super excited and just grateful for the opportunity,” he said. “I’ve heard nothing but incredible things about this locker room and, obviously, playing against them the last year and a half you see the youth and how much the guys care about each other and how hard they play. It’s something that we’ve always admired over in Tampa, so it’s really exciting to be in this position and be able to play with these guys.”

The Orioles sent minor leaguers Jackson Baumeister, Mac Horvath and Matthew Etzel to the Rays for Eflin, who finished sixth last year in American League Cy Young voting. Eflin is under contract for $18 million next season and the Rays decided to shop him.

This stat has been pointed out a few times, but even in going 12-18 the last 30 games, the Orioles gained ground on the Yankees. Yes, that is crazy.

On June 20, before the last 30 games, the Orioles were 49-25 (.662) yet a 1/2 game out of first place. Since June 21, even in losing 18 of 30, the O's still lead the American League East by one game after their loss yesterday and the Yankees' 10-inning victory last night.

The games, beyond the stats, tell us that the Yankees have played poor ball for a long time too. But the Orioles' play has fallen. here is a statistical look:

Here are some O's team stats through June 20 and where they ranked in the major leagues:

* 5.27 runs per game (1)
* OPS of .769 (2)
* Slugging .456 (1)
* Home runs per game 1.61 (1)
* Team ERA 3.13 (tied for 1st)
* OPS against .632 (1)
* 0.83 HRs allowed per nine innings (2)

Jorge Mateo has his left elbow in a brace and no further updates on his health.

Mateo suffered a transient dislocation Tuesday in a collision with shortstop Gunnar Henderson during a 6-3 loss to the Marlins. He needs to undergo further testing but the Orioles are waiting for the swelling to go down.

“It was a difficult moment when I saw and felt my arm bend that way,” Mateo said via team interpreter Brandon Quinones. “Yeah, just a difficult moment for me, for the team, for my family.”

Surgery is a possibility but the medical staff is collecting more information.

“We still don’t have anything concrete,” Mateo said. “We’re still waiting for the team to ultimately make a decision and see what happens from there.”

We have seen the Orioles go 20-9 this year versus the American League East. We have seen them produce nine straight winning months, the longest current active streak in the majors. Since the start of 2023, Baltimore is 162-102 (.614), and that is the best win percentage in the majors in that span.

In the span of four series in June we saw the Orioles sweep four in a row at Tampa Bay and win consecutive series against Atlanta, Philadelphia and the New York Yankees.

But since they capped that four-series run by beating the Yankees 17-5, it has turned for the worse. And the Orioles can't seem to turn it back.

Since June 21 they look nothing like a playoff team. They have two five-game losing streaks in this stretch and in their most recent five games, they are 1-4.

That is a mark of 12-17 and a -41 run differential since that June day.

The trade deadline doesn’t arrive until Tuesday at 6 p.m., but the Orioles got aggressive today. They found the opportunities to strike and didn’t let them pass.

They latched onto a starter under team control beyond 2024 who didn’t cost one of their top prospects. They strengthened their bullpen and added a plus defender for the outfield.

The total cost was outfielder Austin Hays and minor leaguers Jackson Baumeister, Mac Horvath and Matthew Etzel.

Hays went to the Phillies for reliever Seranthony Domínguez and outfielder Cristian Pache. The Orioles later announced that they acquired Zach Eflin from the Rays.

Eflin will report this weekend. Domínguez and Pache arrived at Camden Yards this afternoon.

The Orioles made their move for a starting pitcher on a busy day of roster shakeups.

An industry source confirmed that right-hander Zach Eflin, 30, has been acquired from the Rays for minor league pitcher Jackson Baumeister, outfielder Matthew Etzel and infielder/outfielder Mac Horvath. MLB Pipeline ranks Horvath as the No. 10 prospect in the system and Baumeister at No. 17.

Eflin, who’s under team control for $18 million next season, has posted a 4.09 ERA and 1.164 WHIP in 19 starts with only 13 walks in 110 innings. He went 16-8 last season with a 3.50 ERA and 1.024 WHIP in 31 starts and finished sixth in Cy Young voting in the American League.

This is the controllable starter that the Orioles sought without surrendering one of their top prospects. And they might not be done.

The Padres made Eflin the 33^rd-overall pick in the 2012 draft and traded him to the Dodgers two years later. He was flipped to the Phillies the next day in the Jimmy Rollins deal.
