Top prep and juco prospects in Arizona 

April, 26, 2013

Scottsdale Community College left-hander Stephen Tarpley was on the radar two years ago as a senior at Gilbert (Ariz.) HS, but a knee injury wiped out most of his senior spring, and questions about signability led him to slide in the draft to the eighth round, where Cleveland took him but didn't sign him. After a year at USC where he pitched well, Tarpley transferred back home to junior college and could slide into the top three rounds in this year's draft, which is very light in the left-handed college arms department.

Tarpley was 89-93 on Tuesday, not quite where his velocity was earlier in the spring but still plenty for a left-hander, and he showed some feel for his curveball and changeup, although both pitches were wildly inconsistent, ranging in quality from 35 to 55 (on the 20-80 scouting scale).
