Olsen, who remained in Bradenton, Fla., when the team finished Spring Training, has been making up for time lost early in camp when he was sidelined with a hamstring injury. There has been progress this month, general manager Neal Huntington said, though it's been a much slower process than Olsen had anticipated.
"Good days and other days where, it's not pain, but it's just not coming out the way he wants it to," Huntington said. "So we take a step back and let him continue to rebuild arm strength. The thing that we sometimes lose is that he was coming off of an [arm] injury to finish the season last year and probably would have been behind in Spring Training as it was. The hamstring injury ultimately set him back even further."
Olsen has been throwing bullpen sessions and has appeared in one extended Spring Training game. He is scheduled to throw in a second this week.
