Beating the House

Studes notes that the Yankees are likely to finish around ten games better than the record that would be projected, via Bill James’ Pythagorean theory, from their runs scored and allowed. He notes the teams qualifying for postseason play since 1900 that have exceeded their projections by the most: 1970 Reds (11 games), 1961 Reds (10), 1997 Giants (10), 1931 Athletics (9), 1930 Athletics (8), 2002 Twins (8).
See a pattern? How about their postseason records? 1970 Reds (4-4), 1961 Reds (1-4), 1997 Giants (0-3), 1931 Athletics (3-4), 1930 Athletics (4-2), 2002 Twins (1-4). Total: 13-21, one World Championship (the 1930 A’s, who played a Cardinals team with a nearly identical Pythagorean record).
