Yankees are thoroughly mediocre at best.

Major Baseball League (MBL) average runs scored per game: 4.74.

Yankees runs:
scored: 4.64 (2.1% worse)
allowed: 5.00 (5.5% worse)

Contrary to popular opinion, the defense (pitching and fielding) is worse than the offense. (5.5-2.1)/2.1 = 162% worse.

But neither is terrible, just mediocre ... at best.

Steinbrenner Kids, sell the damn team.
