Arizona Diamondbacks vs Tampa Bay Rays

This is one of the clearest edges on the slate. Drew Rasmussen (2.62 ERA, 0.88 WHIP, 89 K in 86 IP) is dominant, while Merrill Kelly (5.71 ERA, 1.52 WHIP) has been a liability all season. Tampa Bay's offense is elite in recent form — 5.0 R/G L5, .283/.820 — with Caminero, Aranda, and Yandy Diaz all scorching hot (L14 .340+). The Rays are 47-33 and on a W4 streak. Arizona hits RHP poorly (.226/.665) and Kelly's metrics offer no protection. The -198 price is steep but the edge is genuine across all three factors.
