Though still behind schedule and likely to miss one or two starts at the beginning of the regular season, Cole Hamels says he has made “tremendous progress” in bouncing back from an offseason bout of shoulder tendinitis.

“I’m feeling like my body is ready to make a big jump,” the left-hander said.

That jump will come Tuesday when Hamels graduates from flat-ground pitching sessions to throwing off a mound in the bullpen.

“I feel right where I usually am about Feb. 1 going into spring training,” Hamels said. “That’s about the time I’m usually ready for my first ‘pen. I’m happy where I am.”

Hamels shut down his offseason throwing and weight training in late November when the tendinitis first developed. He started lifting weights last week for the first time since Nov. 22 and says he feels stronger. Early in his career, Hamels might have pushed himself to start the season on time. Now 30, Hamels knows his body and the steps he needs to take to prepare for the season. That’s why he’s being methodical in his approach.

“I’m building up for an entire season, for the marathon,” he said. “In the past, I might have ramped it up. Having the experience I do, I’m trying not to overdo it.”
