NEW YORK (AP) Roger Federer has hit another YouTube-worthy, between-the-legs shot at the U.S. Open.

Late in the second set of a first-round match against Brian Dabul of Argentina on Monday night, Federer chased down a lob. A few steps from the wall at the back of the court in Arthur Ashe Stadium, and with his back to the net, Federer smacked the ball through his legs.

The shot cleared the net easily and landed in a corner for a winner beside Dabul, who raised his eyebrows and shrugged his shoulders. Federer celebrated the shot by raising his arms overhead and lifting his right index finger to signal No. 1.

It was a nearly identical shot to a back-to-the-court, through-the-legs passing winner Federer hit against Novak Djokovic in the 2009 U.S. Open semifinals.
