OAKLAND – The Orioles primarily right-handed lineup tonight against Athletics left-hander Ken Waldichuk includes Ryan McKenna in right field and Jordan Westburg playing second base and batting cleanup.

McKenna was recalled today from Triple-A Norfolk, with Aaron Hicks going on the 10-day injured list.

Westburg is making his cleanup debut. He’s the 11^th player to bat fourth this season.

Anthony Santander is out of the lineup after leaving last night’s game with “general soreness,” per manager Brandon Hyde.

Gunnar Henderson moves down to third in the order. James McCann is catching.

OAKLAND – The Orioles couldn’t wait any longer for outfielder Aaron Hicks.

Hicks was placed on the 10-day injured list this morning with a lower-back strain, the move retroactive to Wednesday. Outfielder Ryan McKenna was recalled from Triple-A Norfolk.

Hicks is making his second trip to the IL. He missed three weeks with a left hamstring strain, returned Monday in San Diego and lasted seven innings before leaving with the back discomfort.

“It’s kind of hit or miss right now,” Hicks said yesterday. “What I’m really trying to get over the hump with is hitting. I wake up, I have good mobility, and as soon as I start hitting it kind of starts to flare up a little bit. It’s what I’m dealing with.

“It’s just annoying. Walking around I feel fine, doing little things feel fine, rotation feels fine. And then as soon as I start to try to fire it up and get moving as fast as possible is when it starts wanting to shut down.”

OAKLAND – Orioles manager Brandon Hyde posted another lineup yesterday that didn’t include Aaron Hicks.

Hyde isn’t playing matchups.

He can’t play Hicks.

The veteran outfielder retained his day-to-day status with discomfort in his back. He exited Monday night’s game in San Diego in the eighth inning after singling twice, with Austin Hays replacing him in left field.

Hyde won’t broadcast his players’ availability to the opposing manager, but Hicks didn’t appear in the next two games of the series and followed Thursday’s off-day by sitting again last night.

OAKLAND – Using an opener tonight didn’t work for the Athletics. Bringing in a rookie behind him didn’t work.

The idea of a Jerry Garcia tie-dye promotion also backfired, with the Orioles truckin’ around the bases.

The Orioles scored three times in the first inning, built on their lead with Gunnar Henderson’s long two-run homer in the second, and defeated the Athletics 9-4 before an announced crowd of 8,942 at Oakland-Alameda County Coliseum.

Henderson had three hits and three RBIs by the fourth inning, and the Orioles improved to 75-47 overall, 39-24 on the road, 27-13 in series openers and 16-5 in openers away from Camden Yards.

The win also assured that they would go 79 consecutive series without being swept. They still lead the Rays by two games in the division.

OAKLAND – Orioles manager Brandon Hyde didn’t know which pitcher would start for the Athletics tonight until receiving a text message yesterday afternoon from manager Mark Kotsay.

“Pro move by him,” Hyde said.

Hyde’s club would face an opener, left-hander Francisco Pérez, who’s never started in the majors. Pérez made four relief appearances with the Guardians in 2021, 10 with the Nationals last season and two with Oakland this year.

Pérez hasn’t started in the minors since 2019.

“Usually, if you change your starter, it’s kind of an unwritten professionalism type of thing to let the other team know, as much advance as you can give them. And then you want to reciprocate it, too,” Hyde said.

OAKLAND – Aaron Hicks remains out of the Orioles lineup as they resume their West Coast trip with three games against the Athletics.

Jordan Westburg is batting ninth and playing third base. Adam Frazier is the second baseman.

Adley Rutschman stays in the leadoff spot, followed by shortstop Gunnar Henderson.

Ryan Mountcastle is the designated hitter and attempting to extend his on-base streak to 24 games. Cedric Mullins is batting sixth, followed by Austin Hays.

In Kyle Gibson’s last start in Seattle, he allowed a career-high nine runs and tied his career high with 12 hits. He faced the Athletics on April 10 and held them to one run in 6 1/3 innings.

SAN DIEGO – Be careful with the soft spots in the schedule.

The footing can get slippery.

The Orioles are playing teams below .500 in four out of the next five series, beginning with the Padres and including a trip to Oakland. A reprieve on paper. A trap on the field the past two nights.

Left-hander Blake Snell held the Orioles to two runs over six innings, the bullpen was sturdy, and the Padres won again 5-2 before an announced sellout crowd of 42,318 at Petco Park.

The Orioles have gone 3-3 on their West Coast excursion, and their lead over the second-place Rays is down to two games going into the off-day.

SAN DIEGO – The Orioles are keeping their rotation in line for the series in Oakland that begins Friday night.

Kyle Gibson starts the opening game, followed by Cole Irvin and Kyle Bradish. The six-man arrangement isn't changing.

The club didn’t make a roster move today to bring in a fresh bullpen arm. The off-day on Thursday influenced its decision after Jack Flaherty worked only three innings last night and Nick Vespi threw 34 pitches in two innings.

"It's always helpful," said manager Brandon Hyde. "We're not in great shape, but if worse comes to worse, probably could throw a couple guys that I normally wouldn't throw."

Outfielder Aaron Hicks is out of the lineup again due to back soreness. He might be available off the bench.

SAN DIEGO – Aaron Hicks is out of tonight’s lineup as the Orioles attempt to win their 24^th series.

Hicks didn’t play last night after leaving Monday’s game with back soreness.

Adley Rutschman is serving as the designated hitter. Gunnar Henderson is the cleanup hitter and third baseman. Jordan Westburg is playing second base.

Austin Hays is in left field. Hays homered last night in the ninth inning but is batting .192 since the break.

Ryan Mountcastle has reached base in 22 consecutive games, the longest Orioles streak since Trey Mancini’s 23 from Sept. 5, 2019 to April 2, 2021, and the longest in a single season since Mancini reached in the last 22 games in 2019.

SAN DIEGO – Orioles reliever Jacob Webb achieved two milestones yesterday.

Webb turned 30-years-old, and he reached three years of major league service time. Both round and crooked numbers that made him smile.

“It’s a little bit more special today,” he said. “Kind of a cool little birthday present.”

Webb has been an unexpected gift for the Orioles, getting crucial outs since his arrival a week ago.

Claimed on waivers from the Angels, Webb has appeared in four games and tossed four scoreless innings with only an infield single, one walk and six strikeouts. He set a club record by striking out his first five batters.

SAN DIEGO – Jack Flaherty recorded the last out in the first inning tonight, glanced twice at plate umpire Laz Diaz on his way to the dugout and didn’t break stride.

Diaz didn’t check Flaherty’s hands for a sticky substance until the Orioles were done batting in the top of the second. After Gary Sánchez hit a grand slam as part of a five-run outburst. After Flaherty walked three consecutive batters and threw 34 pitches.  

The Orioles didn’t hold any advantages tonight.

Diaz forgot to do it or yielded to the absurdity.  

Flaherty couldn’t find his command early in his third start since the trade deadline, and the Padres evened the series with a 10-3 victory at Petco Park.

SAN DIEG0 - Orioles outfielder Aaron Hicks returned to the club yesterday after injuring his left hamstring, started in left and exited in the eighth inning with discomfort in his back.

Hicks singled twice but didn’t appear to be running at full speed.

Austin Hays replaced Hicks last night and is starting in left tonight.

“He feels better today,” said manager Brandon Hyde. “Just came out with some back soreness. I don’t know if it was maybe just a little more intensity in these types of games, or maybe locked up on him a little bit. But feels much better today.”

Hicks played two games on his rehab assignment with Triple-A Norfolk. He hadn’t appeared with the Orioles since July 24 in Philadelphia.

SAN DIEGO – Aaron Hicks is out of the Orioles lineup tonight after returning from the injured list yesterday and collecting two singles.

Austin Hays replaced Hicks in left field in the eighth inning, and he’s batting seventh tonight.

Ryan O’Hearn hit his 10^th home run last night and stays in the cleanup spot. Ryan Mountcastle is the designated hitter.

Cedric Mullins is batting sixth. Adam Frazier is starting at second base and Ramón Urías is at third.

Jack Flaherty is making his third start with the Orioles after allowing four runs with 16 strikeouts in 11 innings. He’s 2-0 with a 2.01 ERA in four career starts against the Padres.

SAN DIEGO – Manny Machado dug in against Orioles closer Félix Bautista last night with two Padres on base and one out in the bottom of the ninth inning, back-to-back walks allowing him to represent the potential tying run. Machado took a 101.2 mph fastball out of the strike zone, missed a 100.4 mph fastball, offered at a splitter and grounded it to third baseman Ramón Urías for the game-ending double play.

One team moved a season-high 29 games above .500. The other kept spiraling downward.

The Orioles hadn’t played the Padres since 2019, a year after former executive Dan Duquette began the complete teardown of the club by trading Machado to the Dodgers for five players, including starter Dean Kremer.

Closer Zack Britton was gone a week later, followed by relievers Brad Brach and Darren O’Day, starter Kevin Gausman and second baseman Jonathan Schoop.  

The competitive window slammed shut, and the only sounds left were goodbyes and some tears.

SAN DIEGO – Juan Soto swung the bat with every ounce of strength in his body, almost jumping out of his spikes, and let his momentum carry toward the Padres dugout before regaining his balance. Stumbling out of the box as Grayson Rodriguez’s third strikeout victim. His feet having a mind of their own.

Manny Machado followed with a towering popup and threw back his head in frustration.

Rodriguez was controlling the Padres tonight as if holding a joystick rather than a baseball.

Rodriguez lasted a career-high seven innings, Gunnar Henderson plated three runs with a bases-loaded double in the fifth and the Orioles defeated the Padres 4-1 before an announced crowd of 38,176 at Petco Park.

Ryan O’Hearn homered off Yu Darvish in the second inning, and the Orioles won their third game in a row to improve their record to 74-45 overall, 37-23 on the road and 26-13 in series openers. They also are 44-11 when scoring first, the best record in the majors.

SAN DIEGO – Outfielder Colton Cowser is taking his turn at a minor league reset.

The Orioles optioned Cowser today after he went 7-for-61, creating a spot for Aaron Hicks’ return to the active roster.

“We talked a lot about that with certain guys this year, about how it’s not always a terrible thing to have a guy come up here and experience what major league pitching’s like and what big league life is like,” said manager Brandon Hyde. “Understand how to go through some adjustments when you go back down to Triple-A. It’s like, we saw Grayson (Rodriguez) do that earlier this year, he came back a different guy.

“Colton’s going to be a really good major league player. Got off to a pretty good start, and then he just kind of got caught in between a little bit in his at-bats. I just want him to go down there and free his mind up. Kind of reset a little bit, relax and breathe and go take some at-bats, and don’t worry about trying to produce up here. And maybe we’ll see him soon.”

Hyde noticed that the league got a little more aggressive early in the zone, and Cowser wasn’t able to adjust to it.

SAN DIEGO – Aaron Hicks is starting in left field and batting eighth tonight after his reinstatement from the injured list earlier today.

Cedric Mullins is in center field and batting sixth. Austin Hays sits against Padres right-hander Yu Darvish.

Adley Rutschman stays in the leadoff spot, followed by shortstop Gunnar Henderson.

Jordan Westburg is playing second base and batting ninth.

Ryan Mountcastle, the designated hitter tonight, is slashing .418/.488/.672 with four home runs and 13 RBIs during his 20-game on-base streak.

SAN DIEGO – The Orioles made the anticipated outfield switch today, reinstating Aaron Hicks from the 10-day injured list and optioning rookie Colton Cowser to Triple-A Norfolk.

Hicks strained his left hamstring July 24 while diving for a fly ball in Philadelphia – incorrectly ruled a catch – and returns after two rehab games with Norfolk.

Cowser is 7-for-61 with two doubles, four RBIs, 13 walks, 22 strikeouts and 15 runs scored in 26 games.

Cedric Mullins returned over the weekend in Seattle and won yesterday’s game by robbing Ty France of a home run in the bottom of the ninth inning and delivering a two-run shot in the top of the 10^th. His return cost Ryan McKenna a spot on the roster.

Mullins became the first player to rob a home run and hit one in the ninth inning or later of the same game over the last 10 seasons, per ESPN Stats & Info.

SAN DIEGO – Be truthful and admit if a sense of panic or doubt began to creep in after the Orioles lost two of three games to the Astros at home and the opener in Seattle. And when the teams were scoreless Saturday heading to the top of the 10^th inning at T-Mobile Park.

The retractable sky was falling.

The Mariners won eight in a row and 13 of 15. No one was hotter. But the Orioles prevailed 1-0 in 10 innings and followed yesterday by breaking a 2-2 tie in the top of the ninth, surrendering the tying run with two outs in the bottom half on Dominic Canzone’s homer off Mike Baumann, and responding with a two-run shot from Cedric Mullins in the 10^th to claim their 23rd series.

Mullins took a home run away from Ty France with a remarkable catch right before Canzone’s blast, then pulled a fastball into right field seats for his first homer since July 14, due to a second trip to the injured list.

Félix Bautista wasn’t available after working two innings Saturday. Baumann couldn’t secure his first major league save, but Shintaro Fujinami did. He didn’t have one in Japan, either.

Last night’s 1-0, 10-inning win in Seattle guaranteed that the Orioles wouldn’t be swept in 77 consecutive series.

The Orioles ended the Mariners’ winning streak at eight games. A victory today would seal their 23^rd series.

Cedric Mullins is on the bench today, with Austin Hays playing center field and Ryan O’Hearn in left.

Jordan Westburg is the third baseman and Gunnar Henderson is at shortstop. Adley Rutschman is the designated hitter.

Ryan Mountcastle had a go-ahead RBI single last night in the 10^th and has reached base in a career-high 19 games in a row. He’s batting fifth and playing first base.
