Naomi Osaka, right, of Japan and Karolina Pliskova, left, of Czech Republic shake hands after Pliskova won their final match of the Pan Pacific Open women's tennis tournament in Tokyo Sunday, Sept. 23, 2018.

Chelsea’s 100% record ends with draw at West Ham
As well as a league meeting with Liverpool next weekend, the Blues will face the Anfield club away from home in the League Cup . Cesar Azpilicueta, a two-time Premier League victor with Chelsea , said they must try to challenge for the title this season.
Osaka, who upset Serena Williams in the final in NY, hadn't dropped a set previous to Sunday's final and was frustrated from the outset by the big-serving Czech player.
"If she's on, it would've been nearly impossible to beat her", added Osaka. "I knew I had to play aggressive and make her move around the court, to play with all the energy I had in me and to be positive all the time - that was the goal".
Having not dropped a set over the course of the week, Osaka will next face a player who has needed three dramatic sets in each of her matches to reach her second final of the season.
Ajla Tomljanovic (+9, No.53 to No.44): The Australian was another player to reach a career best mark, after a week in which she reached the Seoul final, losing to Kiki Bertens.
Mourinho skips press conference, insists 'no fallout' between him and Pogba
He has indicated privately he will not look to force a transfer in January but will reassess his options at the end of the season. He told Sky Sports: "The only truth is that I made the decision of Pogba not to be the second captain anymore".
Pliskova then served out the match with a love game, sealing the victory with an ace.
Fourth seed Pliskova was pushed hard by Vekic before winning 6-2, 4-6, 6-3 for a spot in Sunday's final.
It was the Japanese player who appeared the more worn out, however, and Osaka, who had not dropped a set during the tournament, hit a series of unforced errors and showed none of the poise and power that secured her a first Grand Slam title. "I have my weapons, she also has some". That's normal in semi-finals - there are no easy opponents. Osaka, bidding to become the first home champion here since Date in 1995, looked anxious throughout the contest and allowed Pliskova to win easily in just over an hour. "She's a good player, but I'm just happy with my performance this time in Tokyo".
