Jim Leyland's advice to Justin Verlander was simple: Don't rush it. Last week, Verlander had a surgery to repair a core muscle, which is likely to keep the Detroit Tigers right-hander out of the early parts of spring training. Verlander's expected to be fully recovered by Opening Day, and his former manager reached out upon hearing the news. "Just take your time," Leyland said on MLB Network on Tuesday. "A week or two setback is not much, but you try to rush these things and it turns out to be 2-3 months. You don't want that happen. "(The Tigers) know what they're doing. They're going to make sure he's right." Leyland said there were no signs of Verlander's injury during the season. He suffered it while working out last month. Leyland will have a close-up look at Verlander's recovery, though, as a special assistant to president and general manager Dave Dombrowski.
