The San Diego Padres acquired right-handed pitcher Casey Mize and infielder Gage Workman from the Detroit Tigers on August 3, 2026. In exchange, the Tigers received pitching prospects Kash Mayfield and Jackson Wolf. The move bolsters San Diego’s rotation as they sit one game out of a National League Wild Card spot.
The San Diego Padres didn’t just dip their toes into the trade market; they dove in headfirst. In a series of aggressive moves to fix a rotation that has been the team’s primary weakness, the Padres landed Casey Mize in a buzzer-beater deal on Monday. This follows their earlier acquisition of veteran left-hander Robbie Ray from the San Francisco Giants.
For the Detroit Tigers, the trade marks the end of an era for a player who was once the face of their rebuild. Mize, the No. 1 overall pick in the 2018 MLB Draft, spent six and a half seasons in Detroit before this move. The decision to sell came after a disappointing stretch in May where the team went 6-22, causing their playoff odds to sink.
The Cost: Kash Mayfield and Jackson Wolf
To secure Mize, San Diego parted with two left-handed arms. Mayfield has shown a polished approach in High-A Fort Wayne, posting a 3.54 ERA with 62 strikeouts over 53 innings this season.
The Tigers also acquired 27-year-old Jackson Wolf. Wolf’s trajectory has been more volatile; he made a single MLB debut in 2023—coincidentally beating the Tigers—before returning to Triple-A El Paso. According to The Detroit News, Wolf has struggled recently at the Triple-A level, posting a 7.05 ERA and allowing 16 home runs across 89.1 innings.
The Padres also included infielder Gage Workman in the deal, sending him to San Diego alongside Mize.
Mize’s Career Arc and 2026 Performance
Mize’s journey in Detroit was a rollercoaster of elite potential and injury setbacks. After missing most of 2022 and 2023 due to back and elbow surgeries, he broke through in 2025, earning an All-Star selection with a 14-6 record and a 3.87 ERA. However, 2026 has been his most efficient campaign to date.
Despite two stints on the injured list with a groin strain, Mize has been a stabilizer for the Tigers.
| Metric | 2026 Value | Context/Comparison |
|---|---|---|
| ERA | 2.70 | Career-best (down from 3.87 in 2025) |
| WHIP | 0.99 | Down from 1.29 in 2025 |
| Strikeouts | 85 | Across 16 starts (86.2 IP) |
| Home Runs | 5 | Significantly lower than 19 allowed in 2025 |
New Baseball Media notes that Mize currently holds the third-lowest HR/9 (.52) in the Majors among starters with 85+ innings, trailing only Shohei Ohtani and Ranger Suarez. He brings a fastball that tops out at 97 MPH and a versatile mix of sliders and splitters to San Diego.
The Strategic Gamble for San Diego
This isn’t a long-term investment for the Padres; it’s a high-stakes rental. Mize is set to become a free agent in 2027. San Diego is betting that adding Mize and Robbie Ray will provide the depth necessary to leapfrog competitors and secure a postseason berth.
The timing is critical. The Padres enter their series against the Arizona Diamondbacks with a 58-54 record. With expected returns of Joe Musgrove and Nick Pivetta in the coming weeks, the rotation is transforming from a liability into a potential strength.
The trade also reflects a shift in organizational philosophy. While many expected San Diego to be partial sellers, they instead chose to buy, keeping bullpen assets like closer Mason Miller while aggressively adding starting pitching.
Detroit’s Deadline Exodus
The Mize trade is the second major blow to the Tigers’ rotation in 72 hours. On Saturday, August 1, Detroit dealt two-time Cy Young winner Tarik Skubal to the Los Angeles Dodgers for three prospects: Zyhir Hope, River Ryan, and Brady Smith. By moving both Skubal and Mize, the Tigers have effectively pivoted back to a future-focused approach.
Mize seemed aware that his time in Detroit was nearing an end. Speaking Sunday, he acknowledged the uncertainty of his immediate future.
“I’m preparing to pitch Tuesday. I don’t know if that will be here or elsewhere. I am ready for it to get figured out, one way or another.”

The Tigers now hold a growing collection of young arms, adding Mayfield and Wolf to a system that already includes Ben Jacobs and 2026 first-rounder Cameron Flukey. Whether these prospects can replicate the stability Mize provided in 2026 remains the primary question for Detroit’s front office.
