Derek Jeter is running faster to first base this month, but the shortstop insists that his incredible start to the season is the result of sound mechanics that allow him to see the baseball earlier. Jeter takes a 15-game hitting streak into Friday's game against the Tigers. He has a .420 average. "He has a lot more bat speed," said a scout who watched Jeter for three games in Texas. "Compared to last year, it's a lot more. I don't know what he did, but it has worked."
