Casey Mize has officially entered MLB free agency following the conclusion of the 2026 season. The 29-year-old starting pitcher finished his campaign with the San Diego Padres after being acquired at the trade deadline.
Why it matters
Mize is now navigating the offseason as a free agent, with analysts projecting he could command a multi-year deal despite finishing his 2026 tenure on the injured list. His performance variance between his time in Detroit and San Diego remains a key point for interested teams.
Analyst Jim Bowden projects Mize to land a 3-year, $54 million deal as one of 17 potential free agents on the market. Mize posted a 7.46 ERA in 44.2 innings for the Padres, contrasting with a 2.70 ERA in 86 2/3 innings with the Tigers earlier in 2026.

The details
The Padres acquired Mize in 2026 alongside Gage Workman in exchange for Kash Mayfield and Jackson Wolf. Mize, who underwent Tommy John surgery in 2022, ended his 2026 season on the 15-day injured list due to a right ankle sprain sustained in his fourth start with San Diego.

Season Trajectory
Mize enters free agency as a pivotal arm whose availability reflects the broader league trend of teams prioritizing mid-season acquisitions for playoff pushes. His move to the open market forces the Padres to re-evaluate their rotation depth after the 2026 roster shuffling.
The Padres must now account for Mize's departure as they address their rotation needs for the upcoming season. Fantasy managers should monitor his signing destination, as his usage metrics in San Diego—including 19 walks and 25 strikeouts—highlight potential volatility.
The takeaway
Mize serves as a reminder of the risks teams take when trading for pitchers recovering from significant medical history. His upcoming contract will likely hinge on whether front offices view his 2026 Padres performance as an anomaly.
