Several leading baseball experts sent shockwaves throughout the sport Monday, making the boldand some say outlandishprediction that Roger Clemens, a 44-year-old man who will appear in a maximum of 130 of the 1,100 innings remaining in the Yankees' season, may not in fact be able to single-handedly vault his sub-.500 team into first place. 'I am going to go out on a limb and say that this player who will perform in approximately 20 games for the rest of the year will, at the absolute most, have a positive impact on roughly 20 games,' said ESPN's Rob Neyer, turning the sports world on its head. 'Of course, there is always the possibility that several other Yankee pitchers and position players may begin improving in a manner coinciding with Roger Clemens' return, allowing the team to perform at a higher caliber on a daily basis and give the illusion that a man who plays once a week has saved the team. This would simply be happenstance.' Some experts, however, disagree with Neyer's analysis, as New York Post columnist Joel Sherman recently claimed that Clemens will 'win 30 games, mold [rookie starter] Tyler Clippard into a young Roger Clemens within a week, bat over .300 with 20-plus home runs, and make everything all better.'
