21. Yonder Alonso

Position: 1B | Age: 31

Current Team: Mariners | Best Fit: Mariners

2017 Stats: .266 BA, .866 OPS, 28 HR, 67 RBI, 2 SB

Alonso mirrored Logan Morrison for much of the season—a long disappointing top prospect who finally found his power stroke thanks to an uppercut-generating swing (his flyball rate rose from 33% to 43%). Unlike LoMo, he tailed off in the second half, when his OPS fell from .934 to .774. Still, the Mariners liked him enough to acquire him from the A's at the deadline, and a somewhat middling 42 games might not change their minds.
