NEW YORK — The latest on the U.S. Open (all times local):
6:30 p.m.
Roger Federer gives credit where credit is due.
The 17-time major champion says several past opponents helped him become the player he is.
Federer mentioned Andre Agassi and Lleyton Hewitt as the first to force him to improve.
Those two "really made me feel like a bad baseliner to an extent, until I realized I had to move better and be more consistent, have variation in my game," Federer said after his first-round victory at the U.S. Open on Tuesday.
