Larnach, in small sample sizes, has a TON of defensive runs saved. People on this site really need to look at the stats on him on other sites......
As for the OP, this isn't hard at all.
Gallo in left, Buxton in Center, Kepler in right. Larnach at DH. Kiriloff at first. Celestino in AAA. Gordon on the bench. Taylor on the bench, but starting in right against lefties.
