The San Francisco Giants have secured a veteran outfielder for the stretch run but it comes at the cost of a young catching prospect.
Tommy Joseph, 21, was the organization’s second round draft pick in 2009 and he’s moved methodically through the minor league system, one level each year, and landed in double-A to begin the 2012 season. Despite being known as an offensive-minded catcher, the Arizona native has yet to post a wRC+ above 95, meaning he’s struggled to produce league-average offense. Despite that, he’s shown raw power potential and slugged 22 home runs in 127 high-A games last season. This season his isolated power rating has dipped to .132 (from .198 in ’11).
Joseph doesn’t hit for average, his walk rate is modest and he flirts with 20% strikeout rates so he’ll need to remain at catcher to have any true value at the big league level. Defensively, he’s made strides in the finer aspects of his game, which is good news because his strong arm would be wasted at first base and he just doesn’t have the type of profile that hints at future success there.
