The Yankees must hit home runs to win and to be the Yankees.

The 2014 Yankees scored 633 runs and allowed 664.  The Yankee Pythagorean W-L: 77-85.  Actual record: 84-78.  This suggests that the 2014 Yankees were not as good as their 84 wins might suggest.

2014 Yankees hit 147 home runs (HR) led by these, only Yankees in double figures:
Brian McCann 23
Mark Teixeira 22
Brett Gardner 17
Jacoby Ellsbury 16
Carlos Beltran 15.

The Yankee team record for HR is 245 set by the 2012 Yankees (95-67) led by:
Curtis Granderson 43
Robinson Cano 33
Mark Teixeira 24
Nick Swisher 24
Russell Martin 21.

Let's look at two other seasons.

1961 Yankees (109-53) set a major league record with 240 HR led by:
Roger Maris 61; new season record
Mickey Mantle 54
Bill Skowron 28.

1927 Yankees (110-44) 158 HR (11 more than 2014 Yankees) led by:
Babe Ruth 60; new season record; out homered all other AL teams
Lou Gehrig 47; most HR by someone other than Ruth through 1927
Tony Lazzeri 18; third in AL.

Babe Ruth

Except for 2008 (180) the Yankees hit at least 200 HR every year from 2000 through 2012.  Yankee fans were spoiled.
