It's an interesting conundrum.
Ross Mitchell is the pitcher they're referring to. He's our most reliable starter and our best shot to go deep in a game. There's a big upside to him potentially going 9 innings, or even 7+ and saving our bullpen. If he gets the win and Holder has to pitch <2 innings, we'd be in great shape on day 2.
The downside to throwing Trevor Fitts (our Friday guy) is he's the one guy on the team that will NOT go deep in a game. That's not a knock on him, it's just the role he's in. He'll usually go twice through the lineup at most. If we don't get out to a lead (far from a given) and put our bullpen into a bind on Day 1, we probably don't recover from that.
With all that said, I've said all along Mitchell is our best shot at knocking out a great team (and one reason I thought we had a better shot of beating a National Seed in the regional format than best 2-of-3). His numbers won't wow you, though his ERA of 2.10 is nothing to sneeze at. He just gets results. He has 4 CG on the year in 11 starts. In the last three Game Twos of the regular season, he and Holder combined for 3 straight shutouts. He gave up 1 HR in 107 IP and generally is a ground ball machine. He just gives me the most confidence against a great HR hitting team.
As for his "stuff," it doesn't look like much. He's the very definition of a crafty lefty. Lanky guy who wears his pants funny, you're going to look at him warming up and say "We're going to rock this kid." You might do it, UK had success against him in his last outing in the SEC Tournament. But like I said, he and Holder are the two veteran guys I'd go to in a do-or-die situation.
