"I've been doing a lot the last two weeks just to get the arm going and made a lot of good strides," Olt said Monday. "It's just a little fatigue from my shoulder."
The problem hasn't stopped him from playing first base -- where he was scheduled on Monday -- or batting, but he and the team believed a day off would be best. He has yet to play his natural position of third base this spring although he's been taking ground balls there.
"I was pretty worn down from that whole (first) month of spring training," Olt said recently. "We think the day could be the best thing for me."
Olt has worked hard to rebound from an off year in 2013 in which he was troubled by vision problems. He's seen and hit the ball well so far in spring games, tying for the team lead with three home runs.
"We're looking to keep him healthy for the rest of the spring," Renteria said. "I think this fatigue should be OK to get him over there (third base)."
Olt was quick to state this wasn't a setback for him and the shoulder issue isn't a serious problem. He should be back in the lineup on Tuesday.
"Thankfully (we) have a night game (Tuesday) so we have longer respite," Renteria said.
