Roger Federer's coach, Stefan Edberg, was known as an attacking player during his day.
Serving and volleying, as well as chipping and charging the net, helped the Swede amass six grand slam titles in the 1980s and '90s. But not even Edberg employed some of the audacious tactics Federer has used in the past month.
The Swiss approached the net at the Cincinnati Masters after half-volleying second-serve returns, and the unconventional ploy contributed to Federer ousting both top-ranked Novak Djokovic and Andy Murray, then the No. 2, en route to a seventh title.
All eyes were on Federer -- well, they usually are -- to see if the men's record 17-time grand slam winner would stick with it at the U.S. Open.
