HOUSTON -- Jason Jennings' disappointing season came to a definitive halt on Tuesday, after an MRI revealed the right-hander has a tear in the flexor tendon in his elbow.
Jennings is done for the year and will have surgery on the elbow in the next 10 days to two weeks. The right-hander ends his season with a 2-9 record and a 6.45 ERA over 19 games (18 starts).

This injury is likely a continuation of the damage in his elbow that forced him to the disabled list for two months at the beginning of the season.

"One thing we talked about was the fact that pitchers try to compensate for injuries, and they sometimes get into bad habits," general manager Tim Purpura said. "That's some of what has happened here. That's the way Jason described it. He felt like more and more he was doing things that he was trying to get through a performance as opposed to dominating the competition. That's what's happened. He's gotten into bad habits to try to compensate."

Jennings, who is a free agent at the end of the season, hopes to be ready to pitch again by March 1.

The Astros did get some good news on Tuesday as well. Center fielder Hunter Pence has been activated from the disabled list. He had been on the DL with a chip fracture in his right wrist and last appeared in a game on July 22.
