John D. Gaub - S - Chicago Cubs

Cubs purchased the contracts of LHP John Gaub, RHPs Blake Parker and Rafael Dolis, OF James Adduci and C Welington Castillo.
The five are now protected from December's Rule 5 draft. Armed with a fastball clocked as high as 100 mph, the 21-year-old Dolis surely would have been chosen had he been exposed. That said, he's still a bit of a project, posting a 3.79 ERA and 75/53 K/BB ratio in 99 2/3 innings with Class A Daytona in 2009.
