"It felt really good to finally get in a game and finally be out there with the guys," Doolittle said. "Take the training wheels completely off. I don't anticipate any restrictions form here on out."
With 15 days until the A's break camp and head home for the Bay Bridge series against the Giants, Doolittle said he needs just five or six more outings to be ready for the regular season. In 2016, the left-hander had a 3.23 ERA in 44 appearances.
"My delivery is relatively low-maintenance, and I do enough work on the backfields and bullpen mounds that mechanically, I'll be ready," said Doolittle, who was an All-Star in 2014.
