Wilson is working to add a slider to his arsenal of pitches, reports Detroit News.

EDGE Analysis

He has relied mostly on a cutter as his off-speed pitch, but it usually clocks at 91 mph. His fastball ranges in the upper 90s and Wilson fires that pitch about 80 percent of the time. A slider would be a better option, as it would likely hit the radar gun in the mid-80s. Wilson says his health and arm-strength are right on track at this point in the spring and the Tigers will rely on him and Mark Lowe for the seventh and eighth innings. He should deliver a strikeout every inning he pitches and should support those of you who count holds.
