Wacha finished Grapefruit League play with a 0.60 ERA, 0.73 WHIP, .176 BAA and 12:2 K:BB in 15 innings across five appearances.
The veteran right-hander tuned up for his scheduled regular-season debut Monday against the Red Sox with three scoreless innings versus the Tigers on Tuesday -- a game in which he actually served as the bulk reliever behind opener Cody Reed. Adam Berry of MLB.com reports that Wacha is still more likely than not to serve as a conventional starter versus Boston, but manager Kevin Cash said "it's all a possibility" when asked how he might deploy the offseason acquisition during his first regular-season turn in a Rays uniform.
