17. Tampa Bay Rays (29–30, plus-5, LT: 13)
Two and a half years after what looked like a disastrous three-way trade for the Rays, the deal is finally starting to pay dividends. Yes, Wil Myers, who went from Tampa Bay to San Diego, has become an All-Star for the Padres. And yes, Trea Turner, who went from San Diego's system to Washington's, could ignite the Nationals lineup for years to come. But Steven Souza Jr., who came over from the Nats, has started producing the way the Rays have long hoped. The 28-year-old rightfielder is hitting a robust .266/.374/.484; adjust for Tropicana Field’s offense-crunching ways, and that’s a top-15 line for an AL hitter.
Souza’s been an asset on defense too, saving four more runs than the average MLB rightfielder (per Baseball Info Solutions’ Defensive Runs Saved), making him the seventh-best gloveman in the majors at his position. When it comes to diving catches, though . . . well, let’s just say he might’ve peaked in 2014.
