Danielle Collins beats Alize Cornet to reach Australian Open semifinals

I had to finish my forehands.''The temperature hit 97 degrees Fahrenheit on Day 10, continuing a week of hot days at the year's first Grand Slam tournament.Collins won the opening match on Rod Laver Arena before the heat peaked, swinging it in her favor with a key service break in the final game of the opening set on her way to a 7-5, 6-1 victory over Alize Cornet.No. 115-ranked Kanepi made her Grand Slam debut in 2006 but was playing in the quarterfinals in Australia for the first time, completing a career set after making it to the last eight twice at each of the sport's three other major tournaments.She was coming off an upset, three-set win over No. 2-ranked Aryna Sabalenka and took the game to Swiatek, who saved nine set points before losing the first set.Swiatek rallied in the second, exchanging service breaks twice before winning it in a tiebreaker.There was another exchange of breaks early in the third set, and Swiatek was broken again when she was serving for the match in the eighth game.
