One of those interesting situations. Will Harris threw what...4 pitches? Looked great...do you leave him in and just let him go until he gives up a hit, or do you let Osuna come in. I'm fine with either. Edit - One of the reasons I could see Hinch pulling him is just the whole relievers going and sitting for a half inning and coming back out.
I trust Osuna, really I do, but why mess with a good thing? You never know when a guy might not have it. Harris looked to be on his thang so let him deal.
