The rare kind of lefty who can hit the upper 90's, Tigers prospect Casey Crosby has been blossoming in the shadow of super-prospect Rick Porcello, who gets most of the attention. Crosby has a live curve and a developing change, but his command isn't ready for the majors just yet, as evidenced by the iffy ratios he displayed in AA ball last season: 122 hits, 77 walks and 121 strikeouts in 132 innings. If he sharpens his touch a bit, he could step in as a strong number two or three in the Tigers rotation by the end of 2013. He already has good mound presence, great baseball smarts and instincts, and the competitiveness to succeed, so it really does look like a simple accumulation' of time and experience is all that's missing.
