2026 MLB Draft Preview: Liam Peterson scouting report.
The 2026 is about a month away — the first round kicks off on July 11, 2026 — so its time to start offering capsule looks at players the Texas Rangers could select with their top picks. The Rangers’ first round pick is at #16, their second round pick is at #54, and their third round pick is at #89.
Leading up to draft day, we will be doing writeups of some of the players who could end up getting selected by the Rangers with one of their first three
picks. Today we are looking at University of Florida righthander Liam Peterson.
Liam Peterson is a 6’5”, 225 lb. righthanded pitcher for the University of Florida who turns 21 later this month. Peterson attended high school at Calvary Christian in Clearwater, Florida, and was a consensus top 100 guy for the 2023 MLB Draft, but was not selected due to signability issues. He has been a starter for the Gators all three years he’s been there.
Peterson is considered, if not having the best stuff in this draft class, to be near the top. Baseball America did an extensive write-up on him in October, profiling him as potentially the top pitcher in the draft class. His fastball sits in the mid-90s, and can reportedly get up to 98-99 mph. He throws both a slider and a curveball, with the slider being his primary out pitch. Peterson also has a changeup that is relatively advanced, and the changeup can be a weapon against lefties.
The knock on Peterson is his command, with Keith Law, for example, noting that he gets hit too hard for the type of stuff he has, and Fangraphs noting that Florida has had a history of not developing their pitchers as well as they should. The October write-up from BA says that he has a quality fastball, but not one that he can just blow batters, saying that Peterson “will be reliant on command to avoid damage.”
As a freshman, Peterson had a 6.43 ERA in 63 innings over 16 starts and two relief appearances, striking out 77 of 301 batters while walking 44 and giving up 15 homers. He took a step forward in 2025, lowering his ERA to 4.28 in 69.1 innings over 15 starts and a relief appearances, increasing his K total to 96 (out of 305 batters) while lowering his walks to 32 and reducing his homer count to 9.
In 2026, Peterson put up a 4.59 ERA in 16 starts covering 84.1 IP, with 111 Ks, 36 walks and 11 homers, facing 368 batters. He ended the 2026 season on a down note, giving up nine runs in five innings to Troy in the Gainesville Regional. Florida was eliminated by Troy in the next game.
Baseball America has Peterson at #21 on their board. MLB Pipeline has Peterson at #14 on their board. Kiley McDaniel puts Peterson at #13 on his top 150 list. Keith Law’s rankings have Peterson at #8 on his board. Fangraphs has Peterson at #13 on their board. Baseball Prospectus does not have Peterson on their top 30 draft board.
In the most recent Baseball America mock draft, Carlos Collazo has Peterson going to the Rangers at #16. Jim Callis’s June 4 mock draft has Peterson going to the Diamondbacks at #15, but also mentions him in connection with several teams ahead of Arizona. Keith Law’s May mock draft has Peterson going to the Cardinals at #13. Kiley McDaniel’s May 29 mock draft has Peterson going to the Rockies at #10.
I decided to start the MLB Draft preview write-ups with Peterson, since he was who BA has going to the Rangers in the mock draft they released today. The current mocks have him generally off the board before the Rangers pick, so at this point it would be mildly surprising if he dropped to them, but a lot can happen between now and draft day, and things are always fluid once you get past the first handful of picks.
The Rangers hit a home run with the selection of Alejandro Rosario in the 5th round in 2023, whose results in college didn’t match his stuff, though Peterson has had much more success than Rosario did. Its the same idea, though, grabbing a guy with great stuff with the belief that you can refine things and get better results from him. In addition, the Rangers used premium picks in back to back years on Jack Leiter and Kumar Rocker, two guys who were seen as being hit harder in college at times than they should have been, given their stuff. Getting Peterson at #16 would be a major coup if the organization could have the same sort of success with him that the organization did with Rosario.
