The ATP and WTA Tours crowned five winners last week: Caroline Wozkiacki, Lesia Tsurenko, Lara Arruabarrena, Alex Zverev, and Lucas Pouille. Wozniacki (Tokyo) returns to the winner's circle after a calamitous 2016 season which saw her fall to #74 in the rankings before the U.S. Open. Zverev (St. Petersburg) and Pouille (Metz) backed up their hype as "next generation" standouts by winning their first ATP titles. Meanwhile, Tsurenko (Guangzhou) and Arruabarrena (Seoul) each won the second WTA titles of their careers. 

#ThisWeekInTennis recaps the last week of tennis through tweets, articles, podcasts, and rankings. 

RUNDOWN

• Caroline Wozniacki won her first WTA title in 18 months. The former world #1 entered the U.S. Open ranked #74. However, a semifinal run in New York, coupled with this Tokyo title, vaults her back to #22 in this week's rankings. Her Tokyo triumph also means Wozniacki has won a WTA title in nine consecutive seasons.
• Lucas Pouille scored the first ATP title of his career beating Dominic Thiem in the Metz final. Pouille rises to #16 in the rankings while Thiem notched his 6th ATP final of 2016 (four titles).
• Alex Zverev was another first time titlist on the ATP Tour, beating U.S. Open champion Stan Wawrinka to win the St. Petersburg trophy.
• Lesia Tsurenko defeated defending champion Jelena Jankovic in the Guangzhou final. Jankovic also reached the semifinals in doubles alongside Martina Hingis. 
• In one of the more bizarre scorelines you will see in a final, Lara Arruabarrena scored two bagels against Monica Niculescu in Seoul: 6-0 2-6 6-0. 
• Serena Williams announced her withdrawal from all remaining tournaments in the 2016 season save for the season-ending Singapore Championships. 
• Naomi Osaka cracks the WTA top 50 for the first time after making the Tokyo final. 
• The French Tennis Federation extended Benoit Paire's suspension until February 2017.
• Sania Mirza and Barbora Strycova won their second title together from three starts. Mirza has now won eight doubles titles in 2016 and remains the #1 ranked doubles player on the WTA Tour.
• A story that's still developing: Tennis TV will stream only ATP matches in 2017 as the WTA has decided to package their matches separately.

Davis Cup and two WTA events were the extent of tennis action the week after the year's final Grand Slam event. Argentina and Croatia advanced to the Davis Cup final, while Oceane Dodin and Christina McHale won the first WTA titles of their careers in Quebec and Japan respectively. Off the courts, tennis dealt with the hacking of the World Anti Doping Agency (WADA) which revealed the medical records of several of the sports' top players. The issue at hand were several Therapeautic Use Exemptions (TUE) granted to players throughout the course of their careers, substances that without the exemptions would result in a positive doping test and suspension.

​From wta.com: "Dodin twice reached the second round of major tournaments in 2015, but coming into this week in Québec, the fearless Frenchwoman had never won a main draw match outside the Grand Slams - though she did reach the semifinals of a WTA 125K Series event in Limoges."

• More from the Davis Cup: Andy Murray and Juan Martin del Potro played a five-set, five-hour marathon to open the Great Britain/Argentina semifinal tie. 
• A Russian hack of WADA revealed medical information of several top tennis stars, including the Theraputic Use Exemptions (TUEs) granted to Serena Williams, Venus Williams, Rafael Nadal, Petra Kvitova, and others.  
• The hack prompted swift responses from the ATP, WTA, Venus Williams, and Rafael Nadal. 
• CiCi Bellis forgoes her Stanford scholarship and opts to turn pro instead.
• U.S. Open ratings are in and the numbers represent a decline for both the men and women's finals over 2015. 
• Current Wimbledon Junior champ, Denis Shapovalov, won his first ever Davis Cup match in straight sets.
• The Battle of the Sexes happened 43 years ago. 
• The ITF confirms Varvara Lepchenko failed a doping test (meldonium), but will face no sanctions.

Angelique Kerber and Stan Wawrinka are the 2016 U.S. Open singles champions. Kerber leaves New York with her second Slam title of 2016 and the world #1 ranking in her possession. For Wawrinka, he improves to a perfect 3-0 in Slam finals, beating the current world #1 on each occasion. 

#ThisWeekInTennis returns after a two week hiatus to recap all you may have missed during the fortnight of tennis at the U.S. Open. Below you will get a rundown of what happened with some of tennis' biggest stars through tweets, press interviews, articles, podcasts, and rankings. 

RUNDOWN

• Angelique Kerber beat Karolina Pliskova in three sets to capture her second major title of the year, days after securing the WTA #1 ranking. 
• Wawrinka won his first U.S. Open and third major of his career. Wawrinka is now 3-0 in Grand Slam finals and 11-0 in his past 11 ATP Tour finals. 
• Karolina Pliskova followed up her Cincinnati title with a run to the U.S. Open final. Over the course of those two events, she scored five top 10 wins: Kuznetsova, Muguruza, and Kerber in Cincinnati, and the Williams sisters in back-to-back matches at the U.S. Open.
• Novak Djokovic came up short in his quest for a 13th major title, losing in four sets to Stan Wawrinka. His path to the final was one of the more unusual ones you'll ever see. 
• Monfils continued his consistent 2016 campaign by reaching his first semifinal at the U.S. Open. The match, a four-set loss to Novak Djokovic, was the cause of much consternation due to unusual tactics used by the Frenchman. 
• Serena Williams lost her #1 ranking to Angelique Kerber when Karolina Pliskova beat her in the semifinals. Williams' streak of consecutive weeks at #1 ended at 186 weeks, tied with Steffi Graf for the most all-time. 
• Caroline Wozniacki turned in her best major performance in exactly two years by reaching the U.S. Open semifinals. After falling to #74 prior to the tournament, Wozniacki re-enters the top 30 (#29) after winning five matches in Queens. 
• Lucas Pouille scored the biggest win of his career when he beat Rafael Nadal in the fourth round. The Frenchman also obtains a new career high ranking at #18, cracking the ATP top 20 for the first time in his career.
• Andy Murray, fresh off a Wimbledon win, Olympic gold, and a runner-up finish in Cincinnati, entered the U.S. Open as the man most likely to challenge Novak Djokovic for the title. However, Murray was unable to get past Kei Nishikori in the quarterfinals, losing in five sets.
• Anastasija Sevastova retired from tennis in 2013 due to a series of injuries. After mounting a comeback in 2015, Sevastova reached the first Slam quarterfinal of her career before suffering an injury in a lopsided loss to Wozniacki.
• Juan Martin del Potro followed his silver medal at the Rio Olympics with a quarterfinal run at the U.S. Open. Moments before he lost that match against Stan Wawrinka, the New York crowd created one of the most emotional moments of the event.
• Venus Williams held and saved match points against Karolina Pliskova in the fourth round before losing to the eventual finalist in a third set tiebreak. 
• Kei Nishikori reached the second Slam semifinal of his career (2014 U.S. Open final)  before falling to eventual champion, Stan Wawrinka, in four sets. 
• Women's Doubles : Safarova/Mattek-Sands; Men's Doubles: Murray/Soares; Mixed Doubles: Siegemund/Pavic
• Felix Auger-Aliassime and Kayla Day are your Boys and Girls Junior singles champions.
