Just before the dust settled on the 2026 MLB trade deadline, the San Diego Padres made a last-minute trade.

San Diego struck a deal with the Detroit Tigers to acquire right-handed pitcher Casey Mize and utilityman Gage Workman.

Mize took the mound in a Padres uniform for the first time on Wednesday, and what followed was a disastrous and uninspiring performance.

Casey Mize couldn't get through the fourth inning

Mize was opposed by the Arizona Diamondbacks, the same team he made his first start of the season against on March 31.

In that first start, Mize allowed just one run across six strong innings. That was not, though, the way that Wednesday's outing played out.

Mize was shelled for eight runs on nine hits in just 3 1/3 innings. It tied his second-shortest start of the season and is the second time in three starts that he has failed to get through the fourth inning.

The eight earned runs charged to Mize were the most he's ever allowed in a start. To make matters worse, Mize made it through the first two innings without allowing a run. He then proceeded to allow more runs (8) than outs recorded (4) in the remainder of his outing.

Casey Mize isn't the first pitcher to struggle in their first start with a new club

Wednesday's start will certainly be one to forget for Mize, but he isn't the only hurler to struggle in their first outing since being traded.

Tuesday night. It was Freddy Peralta who turned in a horrendous outing in his first start since being acquired by the Tampa Bay Rays.

More big-name pitchers will be making their first starts with their new teams in the coming days, and they'll all surely be hoping to not suffer the same fate as Peralta and Mize.
