Twenty years ago, Buck Showalter was a first-year major league manager. His star player for the New York Yankees was first baseman Don Mattingly.Mattingly, a one-time minor league teammate of Showalters is now the manager of the Los Angeles Dodgers, and though they havent yet met as equals, the admiration is clear.Bucks always been a really smart guy and really organized, great seer, Mattingly said before a Dodgers-Nationals game last week.He knows who can play and who cant, and he knows how youre supposed to play, how you play winning baseball and what you have to do for that.Next April, Mattinglys Dodgers will come to Baltimore for the first time since 2002. Hell get a chance to manage against Showalter then.Bucks slick. I dont have to see him manage to know what hes doing. Im sure hes managing a lot of same with growth, with more games under his belt, Mattingly said.Mattingly coached under Joe Torre and learned a lot from him. He says he learn much from Showalter, too.The details from him, just being sure that Im organized, Mattingly said.How you have to play to win, what your team has to do to win. Theres a lot of difference in having a lot of talent and just going out to play, and playing to win, and having your whole team to buy in to that. Thats the rub of trying to get your guys to do that at the professional level. In college, you just tell them what to do and they do it, Here you cant just tell guys what to do. You have a relationship with guys, and we all want to do this. He knows what hes doing. None of it surprises me with him.
