Porter said Peacock is good to go after a successful bullpen session.
"He didn't have any ill-effects. Actually, it was a really good bullpen [session]," Porter said.
Peacock's overall numbers are not great (1-4, 5.20 ERA), but he's progressed in May. He allowed just two runs in his last outing, an 8-2 win over the White Sox on May 18, and he struck out 11 the start before that.
