Was Scheppers slow to reveal injury?

ARLINGTON, Texas -- Is it possible Tanner Scheppers, wanting to hold on to a coveted spot in the starting rotation, was slow to speak up about the inflamed muscle injury in his right elbow that landed him on the 15-day disabled list on Friday?

Scheppers said the tightness he felt was something new to him.

Manager Ron Washington learned of Scheppers’ injury only late on Thursday, and the Texas Rangers’ manager said Scheppers should have "told me sooner."

Scheppers was handed a 4-0 lead on Thursday, and, after two shutout innings, was tagged for six runs in the third inning. He managed to retire only one Mariner in the third before departing.

The pattern, a few good innings mixed in with a clunker, haunted him four starts into the young season.

"It is unacceptable at this level," said Scheppers, who was the Rangers' Opening Day starter.

Washington said he felt Scheppers transitioned to the starter’s role pretty well. "It has been a learning experience for him," the manager said.

But on how Scheppers handled the injury situation, Washington said he’d rather not comment.

"I haven’t had a chance to dig into it," Washington said.

Scheppers said he still considers himself a starter, and he wants a chance to prove it once he has had a chance to rest his elbow and recover.

When Scheppers’ turn in the rotation comes up again in Oakland, Calif., on Tuesday, the Rangers are leaning in the direction of 23-year-old Nick Martinez.

In one emergency start at Tampa Bay on April 5, Martinez limited the Rays to four hits and three runs in six innings. He was sent to Double-A Frisco immediately after that game.

Martinez impressed Washington: "I hope he feeds off of it."

Beltre a week away?

Adrian Beltre, placed on the disabled list with a strained left quad, could begin fielding practice as soon as Saturday. After a short rehab assignment, Washington hopes to have his third baseman back in the lineup when he is eligible to return next Friday in Seattle.

Let’s get it started

Jim Adduci is in the starting lineup for the first time this season and will play right field. Adduci is the only Rangers position player on the active roster without a start.

"He really needs to play," Washington said.

Regular right fielder Alex Rios will be the designated hitter against the Chicago White Sox, his former team. Mitch Moreland, who has reached base in five of his past seven plate appearances, is not in the lineup.
