Roupp (back) threw a bullpen session Thursday and is on track to make his next scheduled start Saturday against the Cubs, Justice delos Santos of The San Jose Mercury News reports.
Roupp pitched through back discomfort in his previous start Monday in Milwaukee, but he's recovered well enough to avoid missing a turn in the rotation. The right-hander has accrued a 4.22 ERA, 1.31 WHIP and 72:27 K:BB over 64 innings covering 12 starts this season.
