Thanks to Roger Federer's withdrawal from Cincinnati after injuring himself in the final of Montreal Masters against Sascha Zverev, and the absence of Andy Murray, Stan Wawrinka and Novak Djokovic from the tour for the entire hard-court season to date has resulted in Rafael Nadal ascending to the top of the ATP rankings for the 4th time in his career.
#NEXTGEN MASTERS: DIMITROV WINS CINCINNATI, ZVEREV WINS MONTREAL
Grigor Dimitrov wins the Cincinnati Masters by defeating Nick Kyrgios in straight sets. Sascha Zverev won his 2nd Masters title of the year by defeating Roger Federer at the Montreal Masters.
HALEP MISSES (ANOTHER) CHANCE TO REACH WORLD #1
Simona Halep faced off against Garbine Muguruza in the Cincinnati tournament with the #1 WTA ranking on the line. This is the second time this summer Halep has been one match win away from the top spot (previously if she had won the French Open final she would have reached the #1 ranking). This time she did not come close to achieving the result, managing to win only one game against Muguruza. Karolina Pliskova continues her reign at the top for the time being.
AZARENKA OUT OF US OPEN DUE TO CUSTODY BATTLE WITH BABY DADDY
Somehow I missed the announcement that new mother Victoria Azarenka had split with Billy McTeague the father of her son, Leo, a few weeks after Wimbledon. But now the issue is front and center because the custody fight over their son is causing Azarenka to withdraw from the 2017 U.S. Open. McTeague is refusing to give permission for Azarenka to leave the state with their son, even though Azarenka said she would pay for McTeague to stay in a New York City hotel to continue joint custody while she competes in this year's tournament. That was deemed unacceptable by her ex, so forcing the tennis star to choose between her son and playing the last major of the year resulted in the withdrawal.
