Ezequiel Tovar has chipped in 96 hits with 22 doubles, 11 home runs, and 42 RBIs for Colorado up to this point in the season.
I’m on the over in this game. I don’t trust Merrill Kelly’s game on the road at Coors as Kelly has been a hard pitcher to trust season long. On the flipside, Mason Adams has had big time issues of his own, and I think that this ends up being a high-scoring game between these two so give me the over here.
