Kelly will be called up from Triple-A Pawtucket to Boston on Sunday, according to a source, Rob Bradford of WEEI.com reports.

EDGE Analysis

Boston's bullpen, with some assistance from its utility fielders masquerading as outfielders, imploded during an 11-9 loss to the Twins on Saturday. The casualty from that loss was Heath Hembree, who was optioned to Pawtucket immediately following the game, creating a spot on the roster for Kelly, who has not allowed a run while striking out nine in five innings out of the bullpen for the PawSox.
