The biggest movers were the White Sox going up and the Mets going down. Despite losing Jake Peavy for the year, Chicago has enjoyed a hot streak that moved the club into first place in the A.L. Central. In these rankings, the ChiSox still trail Minnesota because the Twins still have superior overall numbers.
The Mets have stumbled of late, falling in the standings to the third-place tie with the Marlins. Philadeliphia has taken advantage and clawed back into second in the N.L. East, though the Phils have also struggled, which is reflected in their own tumble in the rankings.
The Tigers and Angels also took a hit while San Francisco gained some ground on the N.L. West-leading Padres.
*About the rankings: The MLB Power Rankings are compiled using in-season data from numerous statistical categories. These include winning percentage, expected (Pythagorean) winning percentage, runs scored, runs allowed, run differential, team OPS (for and against), record in last 10 games, a strength of division rating, and position in the overall and divisional standings. All data are normalized, weighted, and averaged into a single power coefficient. These are rank ordered 1-30 to provide the final rankings.
