4. Eric Hosmer

Position: 1B | Age: 28

Current Team: Royals | Best Fit: Royals

2017 Stats: .318 BA, .882 OPS, 25 HR, 94 RBI, 6 SB

Hosmer picked a good time to have his best season, as his OPS exceeded his former career high by 60 points. He's also the youngest player on this list. The Royals have a number of key free agents, perhaps signaling the end of their run of contention—but they also have a way of convincing their own players to return at a discount. They'll probably focus most of their efforts on making Hosmer the latest.
