SF fave Murray Chass is all over Cashman and the Yanks front office today for botching the offseason. How? By not acquiring Juan Pierre. Oy. Murray likes Pierre because he seems to think he gets on base a lot, and because he seems to think he’s a good defensive player, and—best of all—because he is reminiscent of Mickey Rivers, and Murray likes Mickey Rivers anecdotes. And, oh yeah, he hit .333 against the Yanks in the 2003 WS (sample size!!!). A dose of reality: As has been repeatedly noted elsewhere in the Yankee blogosphere, Pierre’s OBP is way too dependent on his average, he has no power, and he’s a mediocre defender—basically, a marginal improvement over the Womack-in-center experiment, a debatable improvement over Crosby, but by no means worth trading away minor league prospects.
