Red Sox designated LHP Joel Rodriguez for assignment.
The Red Sox curiously started the season with Rodriguez as their only left-handed reliever while sending Brennan Bernardino to the minors. Rodriguez was then waived in May, made it through waivers, and was sent back to Triple-A, so this is now the second time the Red Sox have designated him for assignment this season. He has a 5.93 ERA in 13 2/3 innings this season and figures to go unclaimed on waivers again. Brad Keller was called up in a corresponding move.
