Clemens has his share of detractors.Die-hard Red Sox fans are unlikely to ever forgive his departure,perceived as being inspired by financial greed.Last year's World Series triumph was overshadowed by a bat-throwing incident that sullied his reputation,and he has spent more than his share of time on the disabled list.At age thirty-eight,the Rocket's days in major league baseball are surely numbered,yet he can still overwhelm even the best hitters,who will likely be feeling his power for a while yet.
