Two good choices. I voted Liriano with the O's numbers against LHP. His command is always a worry. Pearce is an X factor they added. He mashed LHP this year. Liriano has been very good against them last 2 starts.
Stro has been pitching well. Excellent xFIP. Still, when he misses up with the 2S or doesn't elevate enough, he tends to get rocked. 16.5% HR/FB although that's been heading down.
Go with Liriano and is he clearly doesn't have it...quick hook to Stro. At the end of the day, our bats have to roll, or it wont matter.
