Foley (shoulder) will make his next rehab appearance for Triple-A Sacramento, Alex Pavlovic of NBC Sports Bay Area reports.
Foley kicked off his rehab appearance at Single-A San Jose on Sunday, surrendering four runs on two hits and one walk while striking out one over two-thirds of an inning. Despite his struggles, the club has elected to move his rehab to Triple-A. Foley is likely to notch at least a few more appearances before being activated later in the month.
