No. 2: Ryan Mountcastle, SS, Frederick
2016 statistics: .281, 10 HRs, 51 RBIs, 28 2Bs in 115 games (Delmarva)
The 2015 first-round selection (36th overall) bounced back after a horrid start to finish the his first full-season campaign with a respectable stat line. Mountcastle, 20, only hit .162 with 22 strikeouts and just four extra-base hits in 18 games in April. But he batted .337 (57-for-169) with four home runs, 13 doubles and 20 RBIs in 44 games over the next two months. He’s making the climb to Frederick to start the 2017 season.
