Mackenzie Looze continued her strong meet at the 2021 Speedo Summer Championships in Greensboro.

Indiana’s Looze won the 100 breaststroke in 1:08.42 to hold off Ohio State’s trio of Josie Panitz (1:08.86), Hannah Bach (1:08.90) and Leah Baker (1:10.33).

The men’s 100 breaststroke was even closer as Cooper Van Der Laan held off two of Club Wolverine’s best. Van Der Laan won the race in 1:00.20, ahead of Tommy Cope (1:00.30) and Charlie Swanson (1:00.81). Pitt’s Josh Matheny followed in 1:00.91.

In the women’s 100 backstroke, Ali DeLoof went sub-minute to win in 59.96, finishing just ahead of sister Gabby DeLoof (1:00.44).

The men’s other big race was the 800 free relay that saw SwimMAC break the 15-18 national age group record with a 7:22.23.. Tim Connery led off the race with a 1:47.96, which put him in the top 15 U.S. times in that age group.

Following Connery were Logan Zucker (1:51.81), Jacob Wimberly (1:52.09) and Baylor Nelson (1:50.27).

YMCA Hub Fins’ Sam Stewart won the men’s 100 backstroke in 54.59, ahead of Indiana’s Brendan Burns (54.86).

Long Island Aquatic’s Cavan Gormsen, 16, won the 400 free in 4:10.79 ahead of 14-year-old Claire Weinstein of Westchester Aquatics (4:11.11).

In the men’s 400 free, Ohio State’s Charlie Clark won in 3:51.65, four seconds ahead of the field.


The Speedo Summer Championships are taking place as two meets taking place on opposite sides of the country. Half the swimmers are in Greensboro, N.C., while the other half are in Irvine, Calif. The meet replaces the standard end-of-summer championships for senior-level and junior-level athletes, with the two usual events combined due to typical low turnout when the meets are around the same time as the Olympic Games. Older swimmers and 18-and-under swimmers had different time standards required for qualification. Most of the top American swimmers either just finished competing at the Olympics or are taking the summer off after narrowly missing the Olympic team.
