Red Sox demote Joe Kelly to Triple-A

Boston’s roster is being overhauled today. In addition to putting Dustin Pedroia on the disabled list and calling up both Jackie Bradley Jr. and Deven Marrero from Triple-A the Red Sox have also demoted right-hander Joe Kelly to Pawtucket.

Kelly actually managed to stay in the rotation for a month after reports of him being “clearly on thin ice” surfaced in late May, but the Red Sox eventually got tired of waiting for him to turn things around. Kelly posted a 5.67 ERA in 14 starts and heads back to the minors at age 27 and with more than 400 career innings as a big leaguer.

Last year’s trade deadline swap that sent John Lackey to the Cardinals for Kelly and Allen Craig looks like a total bust for the Red Sox. Kelly has a 4.96 ERA in 24 starts for Boston, Craig has hit .130 in 53 games for Boston, and now they’re teammates in Pawtucket.

Justin Masterson will step into Kelly’s rotation spot, although he may not be on the sturdiest of ice himself.
