Mets left-hander Johan Santana hopes to be ready to pitch by Opening Day, but he isn't making any assurances. Santana missed the entire 2011 season while recovering from surgery to repair a torn anterior capsule in his left shoulder. He threw on flat ground from a distance of 90 feet Thursday at the team's spring-training complex in Port St. Lucie, Fla., as he works back from Sept. 14, 2010 surgery. Santana had made a handful of rehab starts at the end of last season before being shut down for the winter to allow his body to recuperate. "Time will tell," Santana said. "As of right now, I'm going to follow everything the way they want me to do, and we'll see how it feels. I cannot tell you what's going to happen five, six weeks from now, because I'd be lying to you. I have to go one day at a time. That's the way we have done things from last year. That's how we're going to do it this year as well. And we'll see by the time spring training and the regular season comes -- are we ready to go? "It's going to be tough for me to guess because I don't know how I'm going to feel in two months."
