ARLINGTON - Rangers manager Jeff Banister on Saturday endorsed Sam Dyson as the closer.

Dyson replaced Shaw Tolleson as the closer in mid-May and had 38 saves in 43 chances to rank 12th among the 18 major-leaguers with at least 30 chances for success rate at 88.4 percent. Add in Dyson's work as a set-up man, and he had 48 holds and saves in 53 chances.

"Closers live on the edge," Banister said during a question-and-answer session with fans at Globe Life Park. "I trust the guy. I trust the stuff. "

Banister acknowledged that he asked much of Dyson. According to Baseball Reference, Dyson tied Milwaukee's Tyler Thornburg, since traded to Boston, for the most high-leverage appearances last season with 43. Leverage reflects the difficulty of a situation when a reliever enters the game.

Beasley set to return: Third-base coach Tony Beasley stayed off the field on doctors' orders last season while fighting rectal cancer. Beasley never stopped watching, and the different perspective showed him that second baseman Rougned Odor and shortstop Elvis Andrus had inconsistent pre-pitch routines.

"It was one thing one pitch and something else the next pitch," said Beasley, who also works with infielders. "That can throw you off and can affect your ability to have range."

Beasley talked about it with both players, but he admitted "sometimes players need a visual." Beasley this spring will be free to demonstrate what he is talking about.

"I have no limitations and can be out there," Beasley said.

According to The Fielding Bible, Anrdus ranked 20th among major-league shortstops with a minus-3 for runs saved, and Odor was 35th among major-league second basemen at minus-9.
