Johan Santana wasn't about to try anything "crazy" on a bullpen mound Sunday at the Mets spring training complex. Just taking the ball with the temperature in the upper 40s and a howling wind might have seemed crazy enough. In less than 10 minutes, Santana was done, having completed his first of many firsts this spring with a 20-pitch bullpen session. It marked Santana's initial appearance on a mound since he was shut down last August because of fatigue. "I don't think it was my best or anything, but it's Day 1," Santana said. "You've got to start at some point, and today was the beginning for me." The 33-year-old Santana's work will be scrutinized all spring as the Mets try to get the left-hander through a full season for the first time since 2008. Manager Terry Collins wants Santana on the mound for Opening Day, on April 1 against the Padres at Citi Field, and another 30-35 subsequent starts. At least, for a change, Santana isn't rehabbing from an injury. He spent this offseason resting, without the burden of a rehab routine to consider. This after spending the previous two winters rehabbing from surgery to repair a torn anterior capsule in his left shoulder.
