Yankees left-hander Andy Pettitte threw a 35-pitch bullpen session off the mound on Sunday, and says he feels like he’s “over the hump.”

Pettitte, on the disabled list since June 27 with a fractured left ankle, came out of the session “feeling good” and said his command was good as well.

“I think he’s making a lot of progress now,” manager Joe Girardi said. “The fact that he’s (throwing) off the mound, he’s comfortable and he’s throwing fine, tells me he’s on the path to getting back. So the next step we’ll have to wait and see exactly what it is, but I imagine he’ll do some type of throwing in three days.”

Pettitte said the next step likely will be throwing live batting practice “as quick as possible.” There is still no timetable as to when he’ll rejoin the Yankees.

His doctor told him “not to go crazy” just yet, Pettitte said, so, until he’s cleared, Pettitte says there’s still a “level of concern.”

Right-hander Ivan Nova (shoulder) also threw a bullpen.

“I guess he felt fine, too,” Girardi said. “We’ll have to see what the next step for him is as well.”

Girardi is unsure as to when first baseman Mark Teixeira (calf) will return.

“I don’t have a guess. The concern there with a calf like that, usually you put a guy like that on the DL, but our thought was we could get him back two or three days earlier,” Girardi said. “But if he does have a setback, you’re probably looking at the rest of the year.”

Teixeira is currently receiving regular treatment, Girardi said.
