Treanor, 34, suffered a bone spur in his right hip when he was with the Tigers last April and was put on the disabled list for the entire season. He signed with the Brewers before this season and joined them at spring training. Treanor has played in 10 spring training games for Milwaukee and was 4-for-20 with five strikeouts and one walk.
"I guess I shouldn't be surprised," Treanor said. "I'm going to a good situation and, hopefully, it works out well for the Brewers, as well. I was just starting to get to really know the pitching staff, and I love the clubhouse here."
Treanor gives the Rangers some more depth at catcher. Jarrod Saltalamacchia was scratched from his start Sunday with inflammation in the rhomboid muscle (goes from the neck to the upper back) and X-rays were negative. He's listed as day-to-day, but his health has been a concern since last season. He has just 15 at-bats this season and would likely play in minor league games to get additional at-bats.
Saltalamacchia is coming off Thoracic Outlet Sydrome surgery last September and had a setback in winter ball, forcing him to cease all baseball activity for a month during the offseason. He missed five days earlier this spring from loose scar tissue. The club said this injury does not have anything to do with the surgery.
Treanor, who is married to two-time gold medal winning beach volleyball player Misty May-Treanor, played five seasons for the Florida Marlins before signing with Detroit last season. He has a .232 career batting average. His highest total of games played was 67 in 2006.
