I'm betting on Luis Castillo to bounce back after a poor outing in his last start with a road win over the Rays.

The veteran right-hander won his previous four starts, holding three of four opponents to two combined runs. The Mariners are in a close division race and are in need of wins, while TB is in a comfortable place in the playoff race. Littell has a 7.44 career ERA at Tropicana Field and is a band-aid rotation piece for Tampa Bay following injuries to Drew Rasmussen, Shane McClanahan, and Jeffrey Springs.

Castillo and the M's, who are 43-34 straight-up following a win, are worth the squeeze at -135 odds!
