"Dominating," Banister said. "His fastball was fresh and his breaking ball was there. He threw strikes. He has done everything we've asked him to do."
The Rangers have three spots open in a bullpen that already includes closer Neftali Feliz, right-handers Tanner Scheppers and Shawn Tolleson, and left-hander Sam Freeman. The Rangers would like one of those three spots to go to a long reliever. Ross Ohlendorf and Jamey Wright have been eliminated, so the Rangers are considering Nick Tepesch and Lisalverto Bonilla.
That leaves two spots. Kela is under consideration along with Jon Edwards, Phil Klein, Roman Mendez and Kyuji Fujikawa. Kela has not allowed a run in 8 1/3 innings. He has given up two hits and two walks and struck out 10.
"I haven't said if he was or wasn't on the team," Banister said. "That decision will be made at the appropriate time. You see what he has done. He has been impressive this spring."
• Rougned Odor left Sunday's game with a bruised left shin. He got clipped by Howie Kendrick sliding into second base on a third-inning steal. He was removed for precautionary reasons.
• The Rangers have released outfielder Ryan Ludwick from his Minor League contract. He was told a few days ago that he would not make the team.
• Shawn Tolleson, who has been sidelined with tightness in his right forearm, pitched a scoreless inning for Triple-A Round Rock against Omaha on Sunday night. He threw 15 pitches.
