But Acta said Friday that Donald, who entered camp as a favorite for such a spot, remains in the driver's seat.
"I've been looking all Spring Training at that," Acta said. "Donald had a leg up because of the job he did last year. We're going to put him in the outfield and we're going to put him in some games at third base, probably, but he's got a leg up. Plain and simple."
That's not to say Lopez couldn't claim a spot, too.
The veteran infielder has some power and is batting .529 (9-for-17) with two homers and five RBIs this spring.
