"We just need to allow it time to heal," Stauffer said. "I expect that rest and treatment will knock it out.
"You never want to end Spring Training not feeling 100 percent, but I've got to deal with it and move on."
Stauffer struggled late in spring and posted a 6.75 ERA. He allowed 17 runs on 35 hits in 22 2/3 innings.
"There's some mechanical things he and [pitching coach Darren Balsley] want to work on," manager Bud Black said of Stauffer. "[We saw] some things on the radar where Tim wasn't throwing the ball like we think he can throw it."
By skipping Stauffer in the first series of the season, the team is giving his triceps time to heal in addition to allowing him to work with Balsley.
"I do think his arm the last two weeks has hit a little fatigue," Black said. "It probably does him some good to back off a few days."
