Padres Pitching Boost: Musgrove & Pivetta Rehab, New Arms Arrive
5 Aug
Summary
- Musgrove and Pivetta began rehab assignments, with Musgrove showing positive signs.
- Pivetta experienced elbow tightness, though bullpen session offered some optimism.
- New pitchers Mize and Ray are set for upcoming debuts against divisional rivals.

The San Diego Padres have significantly strengthened their pitching rotation through recent acquisitions and the return of injured players. On Tuesday, pitchers Joe Musgrove and Nick Pivetta commenced their rehabilitation assignments at Single-A Lake Elsinore. Musgrove completed 2.2 innings, allowing one run while striking out three, marking a positive start to his recovery.
Pivetta's outing was more concerning, as he exited after just 14 pitches due to elbow tightness. However, manager Craig Stammen reported that Pivetta later threw 20-30 pitches in the bullpen without issue, offering some optimism for his continued rehab, with further updates expected Wednesday.
In parallel, the Padres activated new additions Casey Mize and Gage Workman to the 26-man roster. Mize is scheduled to debut on Wednesday against the Arizona Diamondbacks, followed by Robbie Ray on Friday against the Houston Astros. Mize has posted a 2.70 ERA over 16 starts this season, while Ray brings a 3.08 ERA across 122.1 innings.
