Shields, who underwent season-ending surgery on his left knee on June 16 and has been rehabbing near his home in Michigan, was back in Anaheim this weekend for a visit with team doctor Lewis Yocum.
"I think everything is on schedule," Shields said. "I feel really good. There's no limp anymore. I think once baseball activity begins it'll be a little sore."
Shields has been rehabbing his knee by doing light workouts for a little more than an hour each day to strengthen the muscles in and around his knee. He's also said he's been able to ride on a stationary bike without pain.
He walked around the clubhouse with no noticeable limp but said walking up stairs is still the most difficult part since the surgery.
"Going up and down stairs I can feel it a little bit now, but before I was limping going up stairs and using my arms to take off the weight," Shields said.
Shields, who had a 6.62 ERA in 20 outings this season while trying to pitch through pain before electing for surgery, said it's been difficult watching the team this year.
Shields joked that it's tough to stay awake watching the games when the Angels are at home because of the three-hour time difference in Michigan.
But it's been especially difficult for Shields being on the sidelines because he was been one of the more durable players over the past few seasons and hasn't spent much time on the disabled list before this season.
"It's hard but once I had the surgery it kind of eased it because there was no going back," Shields said. "But it's been hard to watch but it's also been fun because they've been playing so well."
