I'm sure I remember it happening a few times but here's one - http://sports.espn.go.com/sports/ten...ory?id=2732384
MELBOURNE, Australia -- While Maria Sharapova and Camille Pin played for almost three hours in blazing sun that created temperatures over 100 degrees, second-ranked Rafael Nadal had the roof closed for the following match on center court on Tuesday. He took advantage with a comfortable 7-6 (6), 6-3, 6-2 win over American Robert Kendrick.
Nadal took just more than two hours to beat Kendrick, who forced him to five sets at Wimbledon last year after taking a 2-0 lead.
This time, Kendrick didn't get a break point against the muscular Spaniard. Nadal got one service break in the second set and two in the third, limiting his errors to 14 against 43 by Kendrick.
Kendrick was throwing everything at Nadal, going for all his shots, lunging and diving all over the court. Kendrick even tossed his racket over the net after an exchange of volleys in the middle of the second set.
The Extreme Heat Policy, which measures conditions by combining the air and court surface temperatures, was invoked halfway through the Sharapova-Pin match.
Current matches were allowed to finish, but no new matches could start on outside courts.
Closing the roof lowered the temperature at center court by more than 20 degrees.
