The waiver wire can offer value in many ways. Sometimes, it provides a temporary fix to an injury issue or it’s simply a case of jumping on a player delivering short-term value. But when you pick up a player and he sticks on your team for all or most of the season and contributes throughout, that is the true definition of waiver wire gold.

Kelenic definitely has power, even if he’s not hitting the ball quite as hard as he did last year. Even so, if this still just 23-year-old kid can ever figure out a way to make better contact, his Triple-A numbers suggest he can be an across-the-board stud. Bear in mind that Kelenic’s hit tool graded at 65 just two years ago, making him a real post-hype sleeper.

Maton may only be a part-time player, but he actually warrants some attention in very deep NL-only leagues if for no other reason than the pop he’s flashed this season. With another hit on Thursday, he’s now slugging .667 and has already managed nearly as many hits this month as he had in the entire month of August. In fact, Maton’s hitting suggests he deserves more action, and as recently as a few days ago, it seemed the Phillies agreed with that assessment. This bears watching.

Unfortunately, the elite walk rate Thomas flashed last year seems like an outlier this season, but again, things are turning around now as he’s already drawn a half dozen free passes this month. A 2014 fifth round pick by Toronto, he wasn’t a hyped prospect in his draft year, but his blend of power and decent speed could help elevate him past projections as a fourth outfielder, and into a player that could provide a decent return on your Fantasy investment. If Thomas’s walk rate bounces back next season, consider him a sleeper in OBP leagues.

How about one earned run allowed since the beginning of June? With his stellar performance this season, Phillips has managed to get his career record back to .500, but the idea that he could be bagging saves for the best team in baseball is not farfetched.
