OAKLAND -- Rangers manager Jeff Banister is taking Shawn Tolleson out of the closer's role. He will be replaced by Sam Dyson.
"We will make that change in the interim," Banister said Wednesday before the Rangers' game with Oakland. "I continue to look at the body of work. Tolleson, going back to last year, was effective, efficient in that spot. Even now he is on top [tied with two others] of the American League in saves.
"It's a tough stretch for him. This is not unlike a position player who is struggling. … Unplug him, give him an opportunity to exhale.
