Haven't announced but likley Reese Olson. He's recently been going about 75 pitches max (~4 starts back from injury). On Thursday last week, he was followed by fellow (former) starter Casey Mize. I dont know if Hinch will trust Mize in a close game though.
Assuming it's not a blow out either way, we will probably see some combo of:
Olson
Holden
Jobe
Hanifee or Guenther
Brieske if late inning crunch
Foleys status is anyone's guess. That's his second f up in the last 10 days.
EDIT: Olson is RHP
