Mike Ashmore of the Hunterdon Country Democrat says the New Yankees have designated left-handed Wilkin De La Rosa for assignment and claimed left-handed pitcher Steve Garrison off of waivers from the San Diego Padres.

According to Tim Bontemps of the New York Post, De La Rosa and teammate Ivan Nova were allegedly injecting each other with B-12 at Double-A Trenton last year. De La Rosa, 25, was 2-4 with a 5.33 ERA in 36 appearances (8 starts) this year for Trenton.

The Padres designated Garrison earlier this week. The left-hander was acquired from Milwaukee back in 2007.  Garrison holds a career 4.05 ERA at Double-A.
