Canadian teen Summer McIntosh did it again.

The 18-year-old made it three world records in less than a week when she broke her own 400-meter individual medley mark late Wednesday night in Victoria, Canada.

McIntosh won at the Canadian swimming trials in 4 minutes, 23.65 seconds to lower her previous best in one of the sport’s toughest events by 0.73 seconds.

Her closest rival was 12 seconds behind.

McIntosh had already broken the world-best mark in the 200 individual medley Monday in 2:05.70, two days after shaving more than a second off the 400 free record in 3:54.18.

The Toronto native also set Canadian marks in two other events: The 200 butterfly, where she was less than a half-second off a record that has stood since 2009, and the 800 freestyle, where she was also just off Katie Ledecky’s world record set last month.

She is slated to compete in those five events at the world aquatics championships in Singapore next month.

COLLEGE TRACK & FIELD

Stephanie Ratcliffe captured Georgia’s first hammer throw title since 2010, and the Bulldogs took the team lead at the women’s outdoor track and field championships in Eugene, Ore.

Ratcliffe, who also won the hammer title in 2023 while at Harvard, had a national-leading toss of 234 feet, 2 inches in the fourth round.

Georgia leads the team standings with 26 points, followed by Illinois with 16.5 and Washington at 16.

The Huskies got a boost when Hana Moll won the pole vault with a collegiate-record leap of 15-8 1/2. Moll, who also won the 2024 indoor title, broke the outdoor record held by her twin sister, Amanda.

Freshman Pamela Kosgei continued New Mexico’s dominance in the 10,000 meters with a meet-record time of 31 minutes, 17.02 seconds. The Lobo men had a 1-2 finish on Wednesday.

Mya Lesnar won the shot put with a first-round toss of 62-4 1/2 to become the first Colorado State athlete to win an outdoor event title since Loree Smith in 2005. Lesnar also won the indoor shot put national title in 2024.

Valentina Barrios Bornacelli secured Missouri’s first individual javelin national title with a person-best throw of 203-5 to leap from fourth place to first on her final throw.

Louisville’s Synclair Savage took the long jump title on her final try with a school-record leap of 22-0 3/4 to move up from fourth.

On the men’s side, Mississippi State’s Peyton Bair followed up his 2025 indoor heptathlon title with a commanding win in the decathlon, scoring a personal-best 8,323 points and winning both the 100- and 400-meter races outright. It was the 14th highest score in collegiate history.

In Wednesday’s late results, Kostas Zaltos won the hammer throw and fellow Greek thrower Angelos Mantzouranis was second to help the Minnesota men take the Day 1 lead.

Zaltos and Mantzouranis are the first teammates to go 1-2 in the NCAA hammer throw since Virginia Tech did it in 2011. Zaltos won with a throw of 256-2 inches in the fourth round to become the first Minnesota outdoor champion since 2018 and just the third since 1971. Mantzouranis, who finished third as a freshman last year, had a personal-best 252-6.

Minnesota sat atop the team standings with 23 points, with New Mexico and Florida tied for second at 18.

NFL

Cincinnati Bengals first-round pick Shemar Stewart’s hold-in escalated to a holdout as he did not attend the final day of the team’s mandatory minicamp.

Stewart has expressed concern over language in the contract that the Bengals presented him and hasn’t signed his rookie deal. He had been participating in meetings and off-field activities but was just watching practices. Thursday, he left the team before the end of the summer program.

The Bengals selected Stewart with the 17th overall pick in the draft. The Bengals’ pass rush was a weak area last season even though Trey Hendrickson led the NFL in sacks, and Stewart has the opportunity to step in as a Week 1 starter on Sept. 7 at Cleveland.

GOLF

South Korea’s Mi Hyang Lee played a six-hole stretch in 6 under and shot an 8-under 64 to take the first-round lead in the Meijer LPGA Classic in Belmont, Mich.

Grace Kim of Australia was a shot back, a year after losing to Lilia Vu in a playoff that also included 2015 champion Lexi Thompson.

Fellow Australian Karis Davidson, Akie Iwai of Japan and Sofia Garcia of Paraguay were two strokes behind at 66 in the final event before the major KPMG Women’s PGA Championship next week in Texas.

TENNIS

German 17-year-old Justin Engel became the youngest player since Boris Becker 40 years ago to reach the quarterfinals of an ATP Tour grass-court tournament by making the last eight at the Stuttgart Open in Germany.

Engel beat seventh-seeded Alex Michelsen of the United States 6-4, 6-4 to become the youngest quarterfinalist ever in Stuttgart. He is the youngest man to reach the quarters of any grass-court event since Becker won Wimbledon as a 17-year-old in 1985.

Engel, who turns 18 in October, will face Félix Auger-Aliassime of Canada today.

MOTORSPORTS

Denny Hamlin will miss NASCAR’s first international race of the modern era to remain in North Carolina following the birth of his child.

Ryan Truex will replace him Sunday in Mexico City.

“See you guys in Pocono,” Hamlin posted on social media.

COLLEGE BASKETBALL

A federal judge denied Tennessee point guard Zakai Zeigler’s request for a preliminary injunction allowing him to play a fifth season of Division I basketball in five years.

U.S. District Judge Katherine A. Crytzer listened to arguments in a hearing June 6 in Knoxville and entered her denial Thursday. She wrote that Zeigler failed to demonstrate he would likely succeed on his argument that the NCAA keeping him from playing a fifth season of Division I basketball is a violation under the Sherman Act.
