Serena Williams was working out on Practice Court 1 on Monday, and between shots glanced over at Roger Federer on the adjacent court to see for herself.
Would Federer practice his daring new shot?
Federer has stirred curiosity on the tour since he unveiled an unusual return of service last month in a tournament in Cincinnati. Before returning an opponent’s second serve, Federer, on a few occasions, darted forward to the edge of the service line and took the ball quickly with a little half-volley.
“I totally look at him,” Williams said Monday night.
