It was a quieter MLB trade deadline for the San Diego Padres compared to previous years. However, the franchise was able to put together a few trades to improve its lineup.
Starting pitching was the Padres’ main priority at the deadline, adding right-handed pitcher Casey Mize and left-handed pitcher Robbie Ray. Along with this, San Diego added depth at the infield while acquiring Gage Workman.

The roster move was to make room for Robbie Ray on the 26-man roster, Acee added.
Ray is scheduled to make his Padres debut on Friday, Aug. 7, in San Diego’s series-opener against the Houston Astros.

Former Padres pitcher German Marquez, 31, spent the first 10 seasons of his major league career with the Colorado Rockies before entering unrestricted free agency this past winter.
The former All-Star starter signed with the Padres on a one-year, $1.75 million contract in February.
He struggled during his time with the Padres in 2026. Through 13 games (10 starts), the righty has a 4-2 record, 5.26 ERA, and 1,49 WHIP in 53.0 innings.
San Diego decided it was time to part ways with the veteran after allowing four hits and four runs in the Padres’ win over the Diamondbacks on Tuesday.
The upgrade to the Padres’ pitching staff at the trade deadline ultimately left Marquez as the odd man out.

It’s safe to say that the Padres upgraded their pitching rotation ahead of the trade deadline by adding Casey Mize and Robbie Ray.
Mize, 29, has put together a career year in 2026. Through 16 starts for the Detroit Tigers, Mize has a 4-6 record, 2.70 ERA, and 0.99 WHIP in 86.2 innings pitched.
The right-handed pitcher has a history of injury scares, serving injured list stints in each of the past four seasons. Casey Mize is scheduled to make his Padres debut in Wednesday’s game against the Arizona Diamondbacks.
San Diego was able to get Casey Mize on a rental year. He is set to hit unrestricted free agency this offseason.
As for Robbie Ray, the 34-year-old lefty has turned his season around after a shaky May. Ray has a 10-6 record, 3.08 ERA, and 1.29 WHIP through 122.2 innings in 22 appearances for the San Francisco Giants this season.
Ray is a multiple-time All-Star and earned the AL Cy Young Award during his time with the Toronto Blue Jays in 2021. Ray is set to hit unrestricted free agency in the offseason.
