5. Stephen Vogt, Athletics
If Stephen Vogt could have had a second half more similar to his first half, then he would’ve been pushing to be atop this list. Unfortunately for Vogt and the A’s, he dropped off pretty significantly in the second half, and while his end result numbers were good, they weren’t great. In the first half, the late bloomer had 14 home runs and 56 RBIs while slashing .287/.374/.498. Those numbers got him to the All-Star Game as a backup to Salvador Perez. It ended up being a tale of two seasons though. In the second half, he hit four home runs, with 15 RBIs and an ugly slash line of .217/.280/.349. Those numbers barely earn you the Mariners starting catcher position. Next year is an important year for the Azusa Pacific graduate. It will be his second full year, and a real test to see whether or not he can establish himself as an everyday catcher. As long as he avoids a second half like last year, Vogt should have no trouble doing exactly that and may very well find himself back in the All-Star Game this year.
