Stripling threw a bullpen session Tuesday in preparation for a possible start on Friday, Ken Gurnick of MLB.com reports.
In preparation for a possible Friday start if Rich Hill (hand) can't go due to a lingering blister, Stripling tossed a bullpen session to give his pitching arm a tune up. The 26-year-old is coming off a win Saturday against the Red Sox where he limited their high-powered offense to five hits and no earned runs over five innings. If he does toe the hill Friday, he'll face off against Ivan Nova and the Pirates.
