Red Sox Magic Number - September 23 - Play-off berth clinched

The Red Sox victory over Tampa Bay on Saturday night, combined with the Tigers' loss to Kansas City, means that Boston becomes the the first team to clinch a play-off berth in 2007. (The Angels are guaranteed at least a tie for the AL West and/or the Wild Card and the Indians are guaranteed at least a tie for the AL Central, but Boston has actually clinched one of the four play-off spots.)

The magic number for the Red Sox to win the AL East is 6, with seven games remaining.

If Boston goes 6-1 (.857), they win the East
If Boston goes 5-2 (.714), Yankees need to go 7-1 (.875) to win.
If Boston goes 4-3 (.571), Yankees need to go 6-2 (.750) to win.
If Boston goes 3-4 (.429), Yankees need to go 5-3 (.625) to win.
If Boston goes 2-5 (.286), Yankees need to go 4-4 (.500) to win.
If Boston goes 1-6 (.143), Yankees need to go 3-5 (.375) to win.
If Boston goes 0-7 (.000), Yankees need to go 2-6 (.250) to win.
