"What we're trying to do is figure out a way to create at-bats for him, which is primarily the reason he didn't stay," D-backs GM Dave Stewart said of playing Tomas at different positions. "If we had more at-bats and could get him more playing time, he'd be here. When he does come back here, we're planning on looking at him to give Jake [Lamb] a breather at third and then we know we've got our outfield positions, he may play some outfield."
Primarily an outfielder while in Cuba, Tomas was asked to make the transition to third base this spring and got most of his reps there.
"We were late in making a decision -- and that's our fault -- by keeping at third base as long as we did," Stewart said.
Tomas may even get some time at first base in case they want him to spell Paul Goldschmidt when Tomas gets back up to the Majors.
"Our intent is when he's back here is to get him as many at-bats as we can and have him be a part of our lineup and be an impact in our lineup," Stewart said. "We believe he's going to hit."
