Yadier Molina is back, and both he and the St. Louis Cardinals couldn’t be happier. After missing the first week of camp for personal reasons, the 39-year-old Molina arrived at the Cardinals’ complex on Monday for what will likely be his final spring training. “It’s been tough the last couple of months but everything is all right right now,” Molina said. “I’m happy to be back.” When St. Louis manager Oliver Marmol welcomed Molina back during a closed team meeting, the cheers and applause from his teammates could be heard outside the concrete building. Prior to that, a grinning Molina couldn’t take more than a handful of steps without a different teammate walking over to embrace him, “I’m already on my third hug completed, just a few minutes ago,” pitcher Adam Wainwright said. “Probably going to head over there for four here in just a minute. Pretty excited my buddy’s back.” With 20 starts together this season, Wainwright and Molina will have 325 as a battery, breaking the major league record held by former Detroit Tigers players Mickey Lolich and Bill Freehan.
