Aaron Jenkins

Thanks to a true 12-to-6 curveball that batters know is coming but still can't hit, Aaron Jenkins has been a strikeout machine. He fanned 15 against Bradley in his final start of the spring, and he owns Northern Iowa whiff records for a season (126 in 95 innings this year) and career (247 in 198 innings). Jenkins also has a high-80s fastball and maintains his velocity deep into games. Though he's a lefthander with a big breaking pitch, Jenkins won't be a high pick. He's just 5-foot-8 and 180 pounds and relies on his curve too much, so scouts aren't sure how long he'll last as a pro. He went undrafted as a sophomore-eligible in 2006.
