The injury happened after Liriano made his 55th pitch of the night. After being examined by trainers, he tried to throw a couple warmup pitches but couldn’t keep going.
Liriano who has had a rocky season, allowed a two-run homer to Anthony Rizzo in the first and left the game allowing 3 hits and 2 earned runs. He struck out 4 and walked none.
If Liriano misses a start or heads to the DL, Vance Worley is the Pirates next internal option to be called up.
