Sunday’s best performance for the Rangers belonged to right-hander Nick Tepesch, who allowed only a bunt single in two innings of work. He struck out the side on 16 pitches in his first inning and then erased the bunt single with a double-play grounder.

Tepesch is a non-roster invitee who has moved quickly through the Rangers’ system. Drafted in the 14th round in 2010, he has zipped through the system in two full years. He finished 2012 with 12 starts at Double-A Frisco. Though he has moved fast and is 24 years old, it seems unlikely that Tepesch could force his way into the conversation for a roster spot.

“He threw the ball extremely well,” Washington said. “He was impressive. If he continues to do that all spring, maybe — maybe — he’ll force us to think about making a decision.”

Briefly: RHP Kyle McClellan had a setback in his return to the mound from shoulder blade soreness. He could not get loose for a planned bullpen session and canceled it. McClellan has fallen a good week or so behind most of the other pitchers in camp. … Washington said that after a full week’s worth of workouts with outfield instructor Gary Pettis, INF Mike Olt is ready to tackle the position in games. … Though 3B Adrian Beltre and DH Lance Berkman did not run the bases as planned during Sunday workouts, it was not because of injuries but, rather, caution due to the cold, windy conditions. Washington said March 1 is a realistic target for Berkman to play.
