Earl Weaver Makes a Comeback?

The Toronto Blue Jays are experimenting with a four-man pitching rotation, the first time a Major League Baseball team has flouted the five-man conventional wisdom since probably 1995, according to numbers-minded baseball analyst Rob Neyer. The move comes just nine months after stat-head Rany Jazayerli authored a wave-making study that declared "the five-man rotation is a failure." More evidence (along with the publication of Michael Lewis' Billy Beane bio Moneyball) that 2003 will be the breakthrough year for the long-marginalized 25-year-old Sabermetric Revolution? Well, it will help if the Blue Jays' four-man rotation fares better than the Red Sox's bullpen by committee.
