"Eric Hinske is part of an interesting piece of Yankee history: The out-of-nowhere slugger. Think Kevin Maas and Shelley Duncan. Hinske now has seven homers in 56 Yankee at-bats. That translates to an average of 12.5 per 100 at-bats.
If the season ended today, Hinske would rank second all-time on the Yankees for homers per 100 at-bats (minimum 50 at-bats). The leader is Shane Spencer, who in his magical 1998 had a 14.93 average. The current second best (awaiting a final result from Hinske) belongs to Glenallen Hill, who raked at a 12.12 homers per 100 at-bats rate in 2000.
So we could be looking at a top three in Yankee history of 1) Spencer. 2) Hinske. 3) Hill. Not exactly what you think when you think Bronx Bombers.
For the record the next best percentages belong to Babe Ruth followed by Mickey Mantle, Roger Maris, another Ruth and another Mantle."
