While Cowser is an obvious nomination after putting up incredible numbers for the Baltimore Orioles this season with 24 homeruns, 69 RBIs, .242 batting average and a .321 on base percentage, the other to finalist are much less of a lock.
Austin Wells finished the season 13 homeruns, 55 RBIs, .229 batting average and .322 on base percentage in almost 20 more games than Horwitz which proves that he could easily take Wells' spot.
