As the Orioles added several players in deals at the trade deadline – including two starting pitchers and two for their bullpen – some promising prospects left the organization.

No doubt for coaches, managers, trainers and all staff on the O’s farm and in their player development system, some players they liked and worked hard to help improve, walked out that door. Relationships were developed and now continue, but the players are no longer with the Orioles.

The O’s traded Connor Norby, Kyle Stowers, Seth Johnson, Moisés Chace, Jackson Baumeister, Matthew Etzel and Mac Horvath, among others, during this process.

On a conference call to announce they had signed top draft pick Vance Honeycutt on Thursday, vice president of player development and domestic scouting Matt Blood was asked if some of the top draft picks the Orioles added this year somewhat offset losing some of the prospects they traded.

“I don’t think they’re related," Blood replied. "We’re just very excited to have been able to select Vance. He’s a player that we’ve liked for a long time. He’s a player that we know is a fantastic person and has a chance to make a big impact at the big league level.”

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.

It was a question that came up during the recent MLB Draft. Why do the O’s draft some college pitchers with modest stats? What do they see here?

Said O’s vice president of player development and domestic scouting Matt Blood: “It’s usually a combination of raw stuff, physical capacity, the athleticism, the way they move and then performance. It’s some sort of combination of those things. We have people that feel with this adjustment or that adjustment or this improvement or this other thing, that they will be better than maybe they have been in the past. It’s a combination of all those things.”

Pitching well right now at High-A Aberdeen we have an example of a pitcher working to improve to be better than he ever has been.

For 22-year-old right-hander Jackson Baumeister, that improvement may be coming with the development of his third or fourth pitch, his changeup.

He already throws his fastball and curveball often and is confident in those solid offerings, but he needs more pitches than those two.

ABERDEEN, Md. - In the last two MLB Drafts, the Orioles have made 40 combined selections and 25 of them have been pitchers. But none were taken higher up the board than last year’s selection of Florida State right-hander Jackson Baumeister with the No. 63 overall pick.

He is the highest drafted pitcher taken by O's executive vice president and general manager Mike Elias since his initial O's draft in 2019.

Baumeister, 21, was selected with a Competitive Balance Round B pick, selections that were made just ahead of the third round of the draft.

After two seasons on the Seminoles staff, the Orioles took Baumeister as a draft-eligible sophomore. He did not pitch after that 2023 draft. but he has made his pro debut this year at High-A Aberdeen and is having a solid first season.

Ranked as the Orioles' No. 11 prospect by Baseball America and No. 18 via MLBPipeline.com, he is 1-2 with a 2.60 ERA. In 14 games over 55 1/3 innings he has allowed 37 hits and no homers with 35 walks and 65 strikeouts. He has a .192 average against and 1.30 WHIP for the IronBirds.

The amateur draft resumes this afternoon with the third through 10^th rounds. The Orioles have nine selections, including a Round 3 compensation pick, the 100^th overall, for failing to sign Oklahoma State pitcher Nolan McLean last summer.

The Orioles are choosing 86^th overall, 100^th, 118^th, 154^th, 181^st, 211^th, 241^st, 271^st and 301^st.

They are thrilled with the results at Nos. 17, 53 and 63.

Picking later than ever under executive vice president/general manager Mike Elias, the Orioles grabbed Vanderbilt center fielder Enrique Bradfield Jr., North Carolina outfielder Mac Horvath and Florida State strikeout machine Jackson Baumeister – a good nickname when you’re a pitcher.

“Ecstatic,” director of draft operations Brad Ciolek said on a video call.
