The Red Sox have signed left-handed reliever Trever Miller to a minor-league contract.
Miller, 38, began the season with the Cardinals and was traded to Toronto as a part of the Colby Rasmus deal. He appeared in six games with the Blue Jays before being released.
A lefty specialist, Miller has pitched just 19.1 innings this season in 45 appearances with both teams. He has gone 01 with a 4.19 ERA.
His numbers this season aren't pretty and at age 38 he may be just about done, but Miller has been a quality left-handed specialist for the better part of a decade and held left-handed hitters to a .203 batting average and .551 OPS last year.
Miller pitched an inning and a third without allowing a baserunner Tuesday night with Pawtucket. Major League rosters are able to expand Thursday.
