D’Backs Designate Juan Jaime For Assignment

The Diamondacks announced that they have designated right-hander Juan Jaime for assignment, making room on the 40-man roster for the recently signed Lyle Overbay.

Jaime, 24, had Tommy John surgery in April 2010 and has not pitched since. Arizona claimed him off waivers from the Nationals during this past offseason. He owns an impressive 11.8 K/9 in 111 2/3 career minor league innings, but has also walked 5.7 batters per nine innings.
