Wacha was placed on the 10-day injured list Tuesday with hamstring tightness, Marc Topkin of the Tampa Bay Times reports.

The 29-year-old was rocked for four runs over 2.2 innings Sunday, and the hamstring issue apparently cropped up while he was doing some running Monday, per Topkin. Wacha isn't expected to face a significant absence and could return when eligible May 13. Rich Hill could be asked to pitch deeper for the Rays with Wacha sidelined.
