Roger Federer has branded his new special move "SABR" - the sneak attack by Roger.
The new shot was invented by the 17-time major champion in Cincinnati last month where he charged his opponent's serve and hit half-volley returns from the edge of the service line.
The audacious move proved a hit with Federer and fans alike, with the Swiss continuing to unleash his latest weapon in tournaments ever since.
Federer eased into the US Open fourth round on Friday with a 6-3 6-4 6-4 win over Germany's Philipp Kohlschreiber and after the match announced a name for his new stroke.
"We sort of came up with that name, sneak attack by Roger, SABR," Federer said.
"I don't know. Call it 'Fed-Attack', call it whatever you want, but I thought it was kind of funny.
"Today again it worked a couple of times. I didn't get that many second serves when I thought I could use it, but moving forward it's an option."
