Treanor, who caught a team-high 67 games with the Rangers last season, returned to the team when it acquired him Wednesday from the Royals for cash considerations.
"He's a great guy, he's a great clubhouse presence and obviously he's a friend of mine," C.J. Wilson said. "To see him come back to join with us for the last couple months of the season and hopefully go to the playoffs again would be pretty cool. He brings extra experience and a lot of positive vibes."
Treanor was Wilson's personal catcher down the stretch last season. He caught Wilson's final three starts, and four of the last six. Treanor also caught all four of Wilson's starts in the playoffs. Manager Ron Washington said Yorvit Torrealba and Mike Napoli will remain his primary catchers, although Treanor might get an occasional game, particularly when Wilson is on the mound.
"I don't know. I won't make that decision right now," Washington said. "It may happen, it may not happen, but I'm not making that decision right now. We've got to get Treanor here."
