Hometown Hero Returns: Rangers Sign Mason Thompson to Minor League Deal, But Can He Regain His Form?
In a move that’s sure to spark nostalgia for local fans, the Texas Rangers have inked a minor league contract with free agent right-hander Mason Thompson, as confirmed by the team’s transaction log on MLB.com. This marks a homecoming for the Round Rock native, who is expected to join the big league camp later this month. But here’s where it gets intriguing: Thompson’s journey back to the mound hasn’t been without its challenges.
Drafted in the third round by the Padres in 2016, the 6’6”, 240-pound hurler has logged innings in four major league seasons, splitting time between the Padres and Nationals. However, his career ERA sits at 5.21 over 114 innings, with a particularly rough 2025 campaign skewing that number. Last season, Thompson posted a staggering 11.81 ERA in just 10 2/3 innings, a stat that raises eyebrows. Yet, it’s crucial to note that this was his first season back after undergoing Tommy John surgery in the spring of 2024—a detail that adds context to his struggles.
Before his injury, Thompson showed promise, delivering 103 1/3 major league innings with a 4.53 ERA. While his 17.7% strikeout rate and 10% walk rate lagged behind league averages, his 51.1% ground-ball rate was a standout strength. His return to the mound saw a dip in velocity on his sinker, though it still clocked in at a respectable 95 mph. He complements this with a four-seamer at the same speed, a mid-80s slider, and an occasional upper-80s changeup.
The Rangers, who pieced together their 2025 bullpen with a series of low-cost, one-year deals, find themselves in a familiar position this offseason: rebuilding their relief corps. They’ve already added veterans Chris Martin, Jakob Junis, Alexis Diaz, and Tyler Alexander on one-year contracts, along with claiming Michael Otañez off waivers. Among Texas’ non-roster invitees, Thompson stands out as the most seasoned bullpen arm—but will experience be enough to overcome his recent setbacks?
And this is the part most people miss: Thompson’s potential isn’t just about his past performance; it’s about his ability to bounce back from injury and reclaim his pre-surgery form. If he can regain his ground-ball dominance and refine his command, he could be a sleeper success story for the Rangers. But is this a calculated risk or a long shot? Let us know your thoughts in the comments—do you think Thompson can turn things around, or is his best baseball behind him?
