Wins across the National League and American League aren’t distributed equally. Looking at both current wins and our projected expected wins, the NL has more teams at the extreme ends of the wins spectrum, while the AL is more tightly grouped. The shape of the win distribution is useful because it can create a picture of the league. The AL has 20 more interleague wins than the NL due to the 140-120 AL-NL interleague record, so the AL’s distribution is shifted slightly higher than the NL’s.
