Rangers top prospect Sebastian Walcott, who is MLB Pipeline's No. 7 overall prospect, will be at Spring Training in Surprise, Ariz., after earning a big league camp invite. In addition, the club signed left-handed pitcher Austin Gomber to a Minor League contract with an invite to spring camp.
The Rangers also extended Major League Spring Training camp invitations to eight other players: infielder Cameron Cauley; outfielders Trevor Hauver and Aaron Zavala; left-handers Robby Ahlstrom, Dalton Pence and Josh Trentadue; and right-handers Eric Loomis and Ryan Lobus.
With today’s transactions, the Rangers have 63 players on the club’s Spring Training roster: a full 40-man roster along with 23 non-roster invitees.
Ahlstrom, 26, began the 2025 season with 6 relief outings at Frisco (AA) before receiving a promotion to Round Rock (AAA) in late April, combining for a 2-4 record, 8 saves, a 3.28 ERA (22 ER/60.1 IP), and 62 strikeouts in 53 total appearances. His 8 saves matched Gavin Collyer for the most by a Texas farmhand last season. In four minor league campaigns (2022-25) within the Rangers chain, the southpaw holds a 3.81 ERA with 10.56 strikeouts per 9.0 innings (319 SO/272.0 IP) in 160 games/18 starts.
Cauley, who turns 23 on February 6, spent all of 2025 with Frisco, slashing .253/.325/.448/.773 (110-435) with 15 home runs, 7 triples, 26 doubles, and 51 RBI in 113 games. The infielder's career-high 48 extra-base hits ranked T2nd in the Texas League, and his 15 home runs equaled a single-season career best (also 2024). Since being selected in the 3rd round of the 2021 MLB Draft by Texas from Barbers Hill (Tex.) H.S., Cauley has posted a .720 OPS with 44 home runs and 189 RBI in 409 minor league games.
Gomber, 32, is a veteran of seven Major League seasons with St. Louis (2018, 2020) and Colorado (2021-25), owning a 35-47 record with a 5.08 ERA (398 ER/705.2 IP), 4.86 FIP, and 539 strikeouts in 168 appearances/124 starts. The southpaw's 28 wins, 109 starts, and 601.2 innings pitched with the Rockies ranked 2nd on the club from 2021-25, trailing only LHP Kyle Freeland in each category. Gomber made 12 Major League starts with Colorado in 2025 before being released on August 22 and completing the campaign with Chicago-NL's Triple-A Iowa affiliate. He was originally selected in the 4th round of the 2014 MLB Draft by the Cardinals from Florida Atlantic University, then was acquired by the Rockies on 2/1/21 in a 6-player trade that sent 3B Nolan Arenado to St. Louis.
Hauver, 27, will be in Major League Spring Training camp for a second consecutive season. The left-handed-hitting outfielder appeared in a career-high 109 games last year for Round Rock (AAA) and ACL Rangers (Rk.), hitting .272/.386/.438/.824 (103-379) to rank among Rangers farmhands in walks (5th, 69), RBI (7th, 66), OPS (8th), and total bases (10th, 166). Hauver owns a career .823 OPS and 67 home runs over five minor league seasons in the New York-AL (2021) and Texas (2021-25) organizations.
Lobus, 25, posted a 7-3 mark and 3.48 ERA (26 ER/67.1 IP) with 82 strikeouts to 27 walks in 45 games/3 starts for Frisco (AA) last season, logging the T5th-most appearances and T6th-most wins of any Rangers farmhand in 2025. The right-hander will be entering his fourth season of professional baseball in the Texas chain having compiled a 15-8 record and 3.53 ERA in 76 games/15 starts since 2023. He originally signed with the Rangers as a minor league free agent on July 18, 2023, following two collegiate seasons at Mercer University in Macon, Ga.
Loomis, the 2025 Rangers Minor League Reliever of the Year, recorded a 2.77 ERA (16 ER/52.0 IP), 1.06 WHIP, and 84 strikeouts across 39 relief appearances for three Rangers affiliates in 2025: Single-A Hickory (7 G), High-A Hub City (25 G), and Double-A Frisco (7 G). The 23-year-old right-hander was a South Atlantic League Postseason All-Star last year, boasting a 1.80 ERA in 25 outings with Hub City. Opponents are hitting just .165 (31-188) with 90 strikeouts against Loomis over his two professional seasons in the Rangers system (beg. 2024).
Pence, 23, went 4-4 with a 2.73 ERA (25 ER/82.1 IP), 103 strikeouts, and 27 walks in 31 games/18 starts for Hickory (A) and Hub City (A+) in 2025, his first season of professional game action after being selected by Texas in the 11th round of the 2024 MLB Draft from the University of North Carolina. Among minor league southpaws at any full-season affiliate last year (min. 80.0 IP), Pence’s 1.02 WHIP ranked 7th and his 31.5% strikeout rate (103 SO/327 BF) ranked 8th.
Trentadue, 24, posted career highs in innings pitched (77.0), strikeouts (94), and starts (16) during a split campaign with Hub City and Frisco in 2025, his third professional season. The left-hander turned in a 1.15 ERA (7 ER/54.2 IP) and 0.84 WHIP in 15 games/9 starts with Texas' High-A affiliate to earn a midseason call-up to Double-A. Trentadue has recorded a 3.28 ERA with 194 strikeouts in 151.0 innings across 49 games/24 starts over three minor league seasons (2023-25) since being chosen by the Rangers in the 14th round of the 2023 MLB Draft.
The 19-year-old Walcott, who is currently ranked as Texas’ top prospect (16th in baseball), according to Baseball America, will be in his second consecutive Major League Spring Training as a non-roster invitee. The Nassau, Bahamas native hit .255 (121-474) with a .741 OPS in 124 games with Double-A Frisco in 2025, recording career highs in home runs (13), RBI (59), walks (70), and stolen bases (32), and earning a selection as the top MLB prospect in the Texas League at season’s end (MiLB.com). Walcott has a .258/.347/.427/.774 (288-1117) slash line and 31 home runs over three seasons in the Rangers system.
The 25-year-old Zavala will be in his second career Major League Spring Training camp with Texas (also 2024) after advancing to Triple-A for the first time in 2025. In 124 games between Frisco (108 G) and Round Rock (16 G) in 2025, the left-handed-hitting outfielder batted .242/.354/.415/.768 (109-451) with a career-high-tying 16 home runs and 68 RBI. Originally selected by the Rangers in the 2nd round of the 2021 MLB Draft, Zavala carries a career slash line of .238/.366/.370/.736 with 43 home runs and 231 RBI in five minor league seasons (2021-25).
