Baltimore The Tigers on Sunday placed left-handed reliever Brant Hurter on the 15-day injured list.Hurter tweaked his lower back after making a pitch in the fifth inning Friday night. The initial diagnosis is lumbar spine inflammation.Hes going to get further evaluation to see the extent of it, manager AJ Hinch said. But its enough to where he needs to go on the injured list.Hurter was pitching on a wet mound Friday and Hinch was asked if that was a factor in the injury.I dont know; I hope not, Hinch said. Nobody wants any injury at any point. We did play through tough conditions, but I dont want to speculate whether that had anything to do with it. There were no other major incidents in the game. I mean, maybe, but I dont feel like its fair to say it was that.Hurter did not make himself available for comment.Right-hander Ricky Vanasco, who was optioned to Triple-A Toledo on May 15, was recalled to replace Hurter on the active roster.The Tigers also called up left-hander Drew Sommers to serve as the 27th man for both games of the doubleheader Sunday.Sommers, who debuted with the Tigers last season, has a 3.10 ERA with the Mud Hens, with 33 strikeouts and 11 walks in 20.1 innings.Its tough to lose Brant, Hinch said. Hes part of our attack plan against every lineup. Especially against lefties. This is a place (against the Orioles) where he was used a lot because of the Orioles left-handed roster. I trust him. Hes a tough look. He can go long and he can go short.Its just another injury we need to deal with.The Tigers are expected to make another roster move between games Sunday. Right-hander Troy Melton is expected to be activated off the 60-day IL and make the start in Game 2. That will require corresponding moves both on the active roster and 40-man roster.Chris.McCosky@detroitnews.com@cmccoskyThis article originally appeared on The Detroit News: Detroit Tigers put Brant Hurter on IL; Vanasco, Sommers called up
