Shifts to 60-day IL
PSan Diego Padres
Forearm
September 1, 2024
The Padres transferred Kolek (forearm) from the 15-day injured list to the 60-day IL on Sunday.
ANALYSIS
The right-hander landed on the shelf in late July due to forearm tendinitis, and he now won't be eligible to be reinstated until after the regular season. Kolek recently resumed playing catch but has yet to throw off a mound, so he still has significant work to do in his rehab program.
