Minor MLB Transactions: 7/20/16

Here are the day’s minor moves, all via Matt Eddy of Baseball America:

• The Red Sox have released lefty Wesley Wright, per Eddy. Wright, 31, had carved out a role as a useful pen piece, working to a 3.26 ERA in 173 2/3 frames over 2011 through 2015. But he has battled through some shoulder issues and has seen his velocity and strikeout rate plummet of late. Wright was carrying a 5.31 ERA at Triple-A Pawtucket.
• Catcher Carson Blair has been released by the Athletics. The 26-year-old appeared briefly in the majors last year, and was outrighted off of the 40-man over the winter. He has struggled in limited action at the Triple-A level, but has handled Double-A pitching quite well (.288/.398/.514) in a slightly more robust sample of 136 plate appearances.
• The Cardinals signed first baseman Efren Navarro, 30, to a minor-league deal. He was hitting just .243/.316/.362 on the year at Triple-A before being released by the Mariners. Navarro has not produced in limited exposure in the majors, but does own a lifetime .308/.371/.438 batting line in 2,672 lifetime plate appearances at the highest level of the minors.
