Coco Gauff won the WTA Finals for the first time by rallying to beat Olympic champion Zheng Qinwen 3-6, 6-4, 7-6 (2) in the final.

The 20-year-old American came from 2-0 and 5-3 down in the final set and was two points from defeat at one stage.

Yet she took the set to a tiebreaker and won the first six points. Zheng threatened a comeback but Gauff took the victory off her third match point with a forehand winner as she came into the net.

She is the first American to win the Finals since Serena Williams in 2014, and received $4.8 million in prize money.

Gauff beat the world’s top two players — Aryna Sabalenka and Iga Swiatek — on her run to the final.

Pelicans Williamson out indefinitely >> Zion Williamson has been diagnosed with a left hamstring strain that will sideline him indefinitely, the New Orleans Pelicans announced.

The diagnosis comes one day after Williamson was scratched from the lineup for New Orleans’ 115-88 loss in Orlando.

That marked Williamson’s fourth missed game in 10 this season.

Soccer

Man City loses 4th straight >> The English champions lost a fourth straight game in all competitions as Brighton came from behind to win 2-1 in the Premier League.

City hasn’t lost four games in a row in all competitions since 2006 — two years before the Abu Dhabi takeover of the club.

Pep Guardiola has never lost four straight matches anywhere in his illustrious managerial career. In his time at Bayern Munich, Guardiola’s team lost three straight games after a penalty-shootout defeat in the 2014-15 season.

Baseball

Japanese Ace Sasaki available to MLB teams >> Japanese ace Roki Sasaki will be available to Major League Baseball teams this offseason.

The Chiba Lotte Marines announced they have chosen to start the process of moving the pitcher to a big league club in North America via the posting system.

Sasaki, who turned 23 this month, is expected to become one of the most sought-after pitchers on the open market. The right-hander went 10-5 with a 2.35 ERA in 18 games this year, striking out 129 hitters in 111 innings.

Because he is younger than 25, Sasaki will be classified as an international amateur free agent subject to bonus pool limits, according to MLB rules. That means his first contract would be a minor league deal no larger than seven figures.
