"I know he's coming off an arm injury," Washington said. "Every day we've seen him throw he's got better and better with his sinker, and it has more life on it. The key is just to keep him healthy. If we keep him healthy, I think this guy will keep us in ballgames, which is important in the starting rotation, because if we get good starting pitching, I like our chances."Jennings would fit into to the middle of a Rangers rotation with Kevin Milwood, Vicente Padilla, Brandon McCarthy and Kason Gabbard. "I'm really approaching this season as a fresh start for me," Jennings said. "I battled arm injures last year and didn't put up the numbers I'd like to. I got the opportunity to come here and play at home. It's a team I think that is up-and-coming, on the rise, and hopefully I can be a part of that." Jennings said his arm "feels good." "It's going to take a little bit for it to get in shape and get it mechanically and physically where I want to be, but as far as the surgery goes and the rehab, it's going very well," he said. "They said it had probably been building for two or three years and it just finally caught up with me last year. It was really giving me problems. It just wasn't allowing me to do what I need to do on the mound to be successful. It was just time for me to take care of it and get it repaired. The surgery went well and everything in the rehab has gone well so far." Washington said coming back from a surgical procedure can be more mental than physical. "The mind plays tricks on you," he said. "He has to free his mind up to let his arm work the way he knows it is capable of working. I think every time he's touched the rubber to throw a bullpen, you can see his arm getting freer and freer, which means the mind is relaxing more. "I believe there will be one day down here this spring when he's going to finally let it go and he's going to realize he's OK. And that's when we're going to see that turbo sinker that he has. He gets a lot of ground balls."
