Tampa Bay rookie Shane McClanahan has electric stuff. He's shown that through two big league starts. But how is his command? How is his control? How much stamina does he have? 

I don't have those questions for Oakland starter Cole Irvin. He's earned trust with me going 3-1 with a 1.42 ERA during his last four starts. Irvin is coming off eight innings of work against the Blue Jays where he allowed only one run with nine strikeouts this past Tuesday. 

The A's are strong at home and have been playing well winning 20 of their last 27 games. 

The Rays have two significant injuries to the middle of their defense with center fielder Kevin Kiermaier and catcher Francisco Mejia both out with injuries.
