Helton Tops in AB per Double

I bet you didn't know that Todd Helson is currently the ALL-TIME best in frequency of doubles, breaking the record held for a long, long time by career doubles champ Tris Speaker. Of course, this is one of those records that can be yours for a time, then lost if future years cause the frequency to go down. As of now, here is the top 10 in At Bats per Double:

1. 12.366, Helton, 4971 AB, 402 2B
2. 12.872, Speaker, 10195, 792
3. 13.563, Chick Hafey, 4625, 341
4. 13.702, Hank Greenberg, 5193, 379
5. 14.033, Edgar Martinez, 7213, 514
6. 14.035, Bobby Abreu, 5165, 368
7. 14.043, Babe Herman, 5603, 399
8. 14.044, Riggs Stephenson, 4508, 321
9. 14.139, Joe Medwick, 7635, 540
10. 14.324, Nomar Garciaparra, 4727, 330

We are in the midst of the 2nd great age of doubles hitting. No one on the list from the 1940's through the 1970's. Martinez led the way that active players Helton, Abreu and Garciaparra have followed in. And Helton has a good lead on Speaker, with the two of them WAY ahead of everyone else in the history of baseball!
