The Casey Mize acquisition has been a roller coaster for the Padres. Sure, San Diego is 3-1 in his four starts but Mize also has posted an ERA of 7.00 over that time period. And I'm not sure things will be much better on Friday night in Tampa. Current Rays are 12 of 29 vs. the right hander, an impressive .414 average with six extra base hits. For Tampa, Shane McClanahan is 7-1 at home with a 2.32 ERA. I'm backing the American League East leaders in Game 1 of this weekend series.
