Jackson has electric stuff but little command

The Tigers get a potential upside play in Edwin Jackson, albeit one who's shown a lot of downside in his career, while the Rays get a partial solution to their right-field hole in Matt Joyce.

Jackson has an electric arm and is able to hold his velocity for 100 pitches, touching 97 or 98 late in the game and sitting in the mid-90s. His hard slider has good tilt with a break that starts early and deepens as the ball travels; he also flashes a below-average breaking ball.

His arm is quick, but there's some effort in the delivery. It's top-of-the-rotation stuff, but Jackson simply does not command either the fastball or the slider, and hitters make far too much contact given the quality of his two main pitches. After two mediocre-to-bad years as a starter, Jackson probably is due for a shot in the bullpen, where Detroit is deficient and manager Jim Leyland has had a lot of success with pitchers who have failed elsewhere.
