Future Hall of Fame manager Jim Leyland isn’t coming back to manage — no matter how nicely anyone asks, and no matter who calls. With speculation already percolating about the Red Sox and their manager John Farrell should he/they suffer a second straight quick exit from the postseason, I thought I’d dial up Leyland to see where he stood. Red Sox president/GM Dave Dombrowski is excellent at his job, but if one thing’s been a struggle for him, it’s finding new managers. Basically, he’s hired two successful managers — and both of them were Jim Leyland. Dombrowski hired Leyland with the Marlins, where they won the World Series in 1997, and he hired him with the Tigers, where they twice reached the World Series. I didn’t mention any possible teams to him, and almost before I could really finish the sentence, the answer about managing anywhere came back. “No … no … not at all. Totally done,” he said about a comeback attempt by phone from Cleveland where he was working on behalf of the Tigers.
