Doctors told him he could resume a throwing program as early as the second or third week in August.
"I'm definitely excited, if that's the case," Kintzler said.
Kintzler was originally diagnosed with a strained triceps, and the fracture was not found until he underwent a bone scan and CT scan earlier this month. He had been trying to rehab at the team's facility in Phoenix.
"It was a mental battle," he said. "They kept telling me, 'You're fine, keep pitching.' I understand, they have to go through their process. ... It stinks that we wasted the whole summer and I couldn't help the team."

Left-handed reliever Mitch Stetter will undergo season-ending surgery for a left hip injury after a second opinion on Wednesday confirmed the Brewers' recommendation. Dr. William Raasch will repair a partially torn labrum in Stetter's hip and remove bone calcification, and may also have to shave down Stetter's femur to relieve irritation.
Left-hander Manny Parra was to resume a throwing program on Wednesday, Kintzler said. The teammates had been rehabbing together in Arizona before Kintzler left for surgery. Parra, who is on the disabled list with a left elbow injury, received platelet-rich-plasma therapy in an effort to avoid Tommy John surgery.
