Catcher Taylor Teagarden is 0-for-18 with 13 strikeouts on the season and Treanor is likely to see far more playing time than he normally would as a backup catcher. He could get the majority of the playing time until Jarrod Saltalamacchia is activated off the disabled list.
"I don't feel my role has changed," Treanor said. "I'm here to catch when they need me to catch. Right now, they want me behind the plate, so I'm going to be ready to play. To me personally, it's nice to play, but still, winning is the biggest thing. That's my focus, to be on a winning club."
Manager Ron Washington said Treanor was back in the lineup on Tuesday because knuckleballer Tim Wakefield was on the mound for the Red Sox.
"I thought the veteran would have a better chance against the knuckleballer," Washington said.
As far as Wednesday night, Washington said, "I haven't decided. I haven't thought that far ahead. I just want to get through this day against Wakefield."
