The Blue Jays claimed shortstop Brian Bocock off waivers, according to a tweet from Andrew Baggarly of the San Jose Mercury News. The 24-year-old appeared in 32 games for the 2008 Giants, but hasn't appeared in the majors since.
He doesn't have much of a bat, as his .228/.301/.311 minor league line suggests. The sample size is limited (227 innings), but UZR/150 suggests Bocock played above-average defense during his 2008 cameo in the big leagues.
