DETROIT — A picture of Jim Leyland's face stared out from the video board at an empty Comerica Park, next to that familiar Olde English "D'' and a message that said simply: "Thank You Jim." After eight seasons managing the Tigers, including three division titles and two American League pennants, Leyland stepped down Monday. His voice cracking at times, his hands wiping away tears at others, he announced his departure two days after Detroit was eliminated by Boston in the AL championship series.
