The home run tied the game 1-1, and in addition, Jeter became only the second player of the previous 28 to hit a home run for his landmark hit -- Wade Boggs, then with the Devil Rays, did that in 1999.
Jeter doesn't hit that many home runs, according to Darren Rovell:
Only 7.8% of Derek Jeter's hits have been for home runs. Only 3.9% of Wade Boggs' hits were home runs. Both hit one for 3000.
Also, the odds against Jeter hitting a roundtripper were fairly high:
Bodog's odds on Jeter hitting a home run for hit #3000 was 10 to 1. Only Triple (15 to 1) was higher.
