Dave Duncan is uninterested in becoming the next manager of the Houston Astros. ?My interest right now is to be the best pitching coach for the St. Louis Cardinals for the remainder of the season and through the postseason,? said Duncan, the highest-paid coach in baseball. ?I don?t really want to get distracted with anything that?s going to take away from that. I?m just going to concentrate on doing my job right now and finishing the season.? Duncan had an interest in managing earlier in his career, but has settled into his role as an elite pitching coach. ?Earlier in my career, I think I had a desire to manage more than I do now,? Duncan said. ?I don?t think that you go into the job like that without making a really strong commitment. And usually it has to have some length to it. So my interest right now ? you know, I?ve been around a long time, and I don?t know whether I?d have the same desire to make that type of commitment than I might have in years past.?
