"We're just trying to get them some at-bats over the next few days," manager Ron Washington said. "Let them pile up some at-bats and speed them up a little bit."
Beltre was hitting .333 with seven singles in 21 at-bats. He is out of options and must make the Opening Day roster or be exposed to outright waivers before he can be sent to the Minors.
Michael Choice, who was batting fifth against the Athletics on Saturday, has had the best spring of any Rangers outfielder. He went into Saturday hitting .364 (12-for-33) with three doubles, a triple and a home run. So far there are no indications he could take the center field job away from Martin. But the Rangers do want to get Martin going at the plate.
"I'm feeling better about taking more pitches," Martin said. "But I don't feel comfortable in my swing and my timing. That's what I'm working on. Nothing bad. There are two weeks to Opening Day. That's enough to be ready."
