Oleksandr Usyk knocked out Daniel Dubois in the fifth round and became the undisputed world heavyweight champion for a second time on Saturday.

The undefeated southpaw retained his WBA, WBC and WBO belts and regained the IBF belt he relinquished just over a year ago.

The Ukrainian dropped Dubois twice in the fifth — the second time with a lunging left cross. The London native looked stunned on the canvas and couldn’t beat the count at a packed Wembley Stadium.

Usyk (24-0, 15 KOs) beat Dubois for the second time in under two years and this time there was no low-blow drama. It was a ninth-round stoppage in Poland with, of all things, a straight jab. But the finishing shot Saturday was a no-doubter.

Unrivaled announces NIL deals with Watkins, Johnson >> JuJu Watkins, Flau’Jae Johnson and Azzi Fudd are three of 14 top women’s college basketball players that Unrivaled is signing to NIL deals, the league announced Saturday.

It’s the second consecutive year that the 3-on-3 league that was founded by Napheesa Collier and Breanna Stewart has had name, image and likeness deals with college players. In it’s inaugural season, Unrivaled had deals with Paige Bueckers and Johnson.

Watkins, who plays for Southern California but is sidelined with an ACL injury, has also previously been involved with Unrivaled as an investor in its Series A funding round.

Johnson, who is at LSU, and Fudd, at UConn, both were on hand for the announcement, as were Notre Dame’s Hannah Hidalgo and UConn’s Sarah Strong.

“Unrivaled is doing something amazing for women sports. It’s a big reason why we’re all here today,” Johnson said at Unrivaled’s pop-up headquarters in Indianapolis. “They’re doing it in the W and really giving us a chance in college to really go at it.”

Former A’s Scout Bittiger dies at 63 >> Jeff Bittiger, a pitcher who played four seasons in the major leagues and spent the last 22 years as a scout in the Athletics organization, died, the A’s announced. He was 63.

The team did not disclose a cause of death.

Born in Jersey City, New Jersey, Bittiger made his major league debut for Philadelphia on Sept. 2, 1986. The 5-foot-10 right-hander went 4-6 with a 4.77 ERA in 33 appearances for the Phillies, Minnesota Twins and Chicago White Sox.

Mets induct wright into hall of fame >> The New York Mets inducted David Wright into their Hall of Fame and retired his No. 5 — nearly 21 years after his big league debut.

Wright, who debuted against the Montreal Expos on July 21, 2004, appeared to be on track to join Robinson and Brett as a Hall of Fame third baseman when he hit .301 with 222 homers, 876 RBIs and an .888 OPS through his first 10 seasons.

But Wright played just 211 more games while battling chronic back, shoulder and neck injuries as well as a diagnosis of spinal stenosis.

White Sox place All-Star Smith on IL >> White Sox rookie Shane Smith was placed on the 15-day injured list with a sprained left ankle, four days after the right-hander pitched in the All-Star Game as Chicago’s lone representative.

The White Sox did not immediately provide details on how or when the injury occurred. Smith pitched three innings in a loss to Cleveland on July 11, an abbreviated start that manager Will Venable said was planned.

The 25-year-old Smith is 3-7 with a 4.26 ERA in 18 starts. Chicago selected him in the Rule 5 draft in December, and he became the second player to make an All-Star team in the year immediately after being taken in that draft.
