After a pensive day waiting for results of an MRI exam on third baseman Adrian Beltre’s sore quadriceps muscle, the Rangers decided they were willing to wait a little longer for him.

The Rangers decided to hold off on placing Beltre on the disabled list.

Instead the Rangers will push back the activation of RHP Colby Lewis by at least two days to Monday or Tuesday, giving the Rangers more time to make the decision.

“It wasn’t as severe as we originally feared,” Rangers general manager Jon Daniels said. “It was a mild Grade 1 strain. We’re going to play it conservatively and give it a few days Then we will make a determination on whether it needs to be a DL move or if Adrian can manage it.”

The downside of the situation is that the Rangers are forced to push Lewis’ return to the rotation back a couple of more days to keep the roster as flush with options for the bench and bullpen as possible. Instead, Tanner Scheppers and Martin Perez will follow Yu Darvish, who starts Friday’s series opener against Houston, to the mound this weekend. The Rangers will then either go with Lewis or Robbie Ross on Monday. The other will pitch Tuesday.

If Beltre shows the ability to be able to play with the injury, then either an infielder would have to be taken off the roster or the club would have to trim down to six relievers. The Rangers have carried seven relievers for at least the last decade.

Lewis had the ability to take his free agency on Thursday if not guaranteed a spot in the rotation. Daniels said pitching coach Mike Maddux and manager Ron Washington both spoke with Lewis on Thursday and that the pitcher was willing to wait a few more days for his first start since July, 2012 when forearm and hip issues required surgery.

Beltre, who turned 35 on Monday, left Tuesday’s game after a fifth-inning double due to tightness in the center of the left quad. He returned to Texas ahead of the team Wednesday to undergo the MRI.
