Season Batting Averages 33% above League

Click link to view October 24, 2011 document.

Data is for the American League (AL) and the National League (NL) 1903-2010, minimum 300 At Bats (AB).

There were 192 seasons that met the criteria, including eleven of twelve .400 BA; Bill Terry's .401 in 1931 did not: (.401-.303)/.303 = 32.3%...

Twelve were at least 50% higher the league Batting Average (BA).  Ten of the twelve were between 1904-1918. (seven by Ty Cobb)

31 players did this more than once (led by Cobb: 14)

Ty Cobb had 7.14% of the seasons.
__________________________

Rogers Hornsby's .403 in 1925 was the only .400 BA less than 40% above league: 38.2%.

Nap Lajoie's .384 in 1910 was the highest: 58% above league.

Ted Williams: .406 in 1941 and .388 in 1957 were both 52.2% above league.

Cobb had the biggest point difference: 1911: .4196 - .2730. = .1465.

Complete list. Brett: 44.85% above lgBA. The lgBA I used in 2011 when I researched this was for all batters. BB-Ref excludes pitchers, so there is a slight difference in non-DH seasons.
