Joe Mauer's promising rookie season gets put rapidly on the shelf, as he'll need knee surgery and is expected to miss a month. Matt LeCroy, the only plausible alternative with the bat at the position, left tonight's game in the 2nd inning with a rib injury. Johan Santana left last night's game with cramps in his pitching arm, while Torii Hunter's hamstring is ailing and could sideline him for4 or 5 days. Tough times in Minnesota.
