Baumeister was a talented two-way player in high school as a catcher and pitcher who ranked as a top-100 player in the 2021 draft class. A draft-eligible sophomore in 2023, Baumeister pitched out of the Florida State bullpen during the 2022 season, where he posted a 5.60 ERA over 27.1 innings, while striking out 41 and walking 20. He struggled significantly with his control but showed improvement in that area through five starts and 17 innings with Hyannis in the Cape Cod League, where he posted a 3.71 ERA and struck out 25, while walking eight. Those control improvements translated to the 2023 season, where the 6-foot-4, 226-pound righthander posted a career-best 9.4% walk rate, with a 4.96 ERA over 69 innings. Baumeister’s arsenal is led by an excellent fastball that sits around 93 mph and has touched 98. What makes the pitch special is the above-average induced vertical break, over 17 inches, that also comes with tremendous extension and a flat approach angle that all help the pitch play above its velocity. Baumeister’s go-to secondary is a mid-70s top-down curveball that looks average, and he has also thrown a mid-80s changeup that could be a decent offering for lefthanders. He also added a new slider in the low 80s but he struggled to get on top of the pitch consistently and used it just 7% of the time.

BA Grade/Risk: 50/High
Adjusted Grade: 35
Track Record: The 63rd pick in the 2023 draft, Baumeister was the Orioles’ highest drafted pitcher under Mike Elias until 2025. If he makes the majors, it will be for another team. The O’s sent him to Tampa Bay in the 2024 Zach Eflin trade and he is now the Rays’ best hope for a useful return on the deal. Mac Horvath has settled into more of an org player while Etzel was traded for Nick Fortes.
Scouting Report: Baumeister had an eventful 2025 season, with parts he would rather forget. He was shelled to the tune of a 9.95 ERA in April, and after a much better May, he missed two months with a shoulder injury. Returning to action in August, he looked much more like the pitcher the Rays traded for with a sub-1.00 ERA over five starts. His Arizona Fall League stint came to a premature end because he was hit in the head by a 110 mph line drive. Thankfully, he was not seriously injured. Baumeister’s lively 93-95 mph fastball gets swings and misses at the top of the zone. He has transformed his slider into a harder 87-89 mph cutter that he can locate in the zone and is average. He now relies much less on his slower curve and the feel for it has backed up. His below-average changeup remains a developing pitch.
The Future: Baumeister needs more consistency, but at his best, he can carve through a lineup multiple times. He will go to spring training competing for a spot in Triple-A Durham. He projects as a No. 4 starter.

BA Grade/Risk: 50/High.
Track Record: Baumeister became the first pitcher the Orioles had drafted in the top two rounds under Orioles head Mike Elias. After a solid but walk-filled first half with the Orioles, Baumeister was then quickly traded to the Rays in the July 2024 Zach Eflin deal. After the trade, he dominated for High-A Bowling Green and picked up the win in the South Atlantic League championship clincher.
Scouting Report: Baumeister is yet another Rays pitcher with a lively and flat plus four-seam fastball that works at the top of the zone, which allows it to play well despite modest 92-94 mph velocity. Baumeister made one subtle but significant change as a Ray. He started relying much more on his average low-80s slider, which unlocked significant control gains. Baumeister threw his slider for strikes 62% of the time compared to a 49% strike rate with his fringe-average mid-70s curve. Considering he also struggles to throw his below-average changeup for strikes, the switch gave Baumeister a second pitch he could throw in the zone. His walk rate with the Orioles was 13.9%. As a Ray, it was 4.8%.
The Future: Baumeister has always battled control issues, but the Rays seem to have helped him adopt an approach that gets him ahead in the count more often. His secondaries still need to improve, but his fastball should at least get him to a solid relief role, and if he can make further strides with his strike-throwing and secondaries, he could be a midrotation starter.

BA Grade: 50/Very High
Track Record: Baumeister was one of the highest-rated high school players eligible for the 2021 draft who made it to college, but he did so knowing he would be an eligible sophomore two years later. The Orioles drafted him 63rd overall out of Florida State in 2023 and signed him for an above-slot $1.605 million as the highest-drafted pitcher under Mike Elias. The Orioles appreciated his hoppy fastball and potential to further develop his arsenal, but they also valued his aptitude to make adjustments as his season went on and willingness to learn. Baumeister didn’t pitch in game action after signing.
Scouting Report: Baumeister’s fastball, which in college sat around 93 mph and touched 98, features above-averaged induced vertical break with elite extension and a flat approach angle that helps it play up in the zone. The club believes a focus on elevating it could lead to immediate improvements in results. Baumesiter’s curveball had at least average traits but was inconsistent, while the Orioles believe the slider he added during 2023 has the potential to grow into his best secondary pitch. Even if his changeup remains a fourth pitch, the Orioles believe his arm strength and ability to spin the ball can give him a starter’s arsenal going forward.
The Future: Baumeister has the potential to be the best pitcher the Elias Orioles have drafted, with a midrotation upside and the chance for more if he can consistently throw his most effective breaking balls. He could move quickly through the system but likely will start at Low-A Delmarva in 2024.
