• Regan Smith lowered the American short-course 200m butterfly record to 2:00.28 for the third-fastest time ever, then split backstroke victories with Kaylee McKeown across the 100 and 200.
• Shaine Casas set a U.S. record of 1:49.43 in the 200m individual medley to beat training partner Léon Marchand, who left Carmel winless and is not expected to swim all three stops.
• The series continues next weekend in Westmont before Toronto, and Summer McIntosh could still race after withdrawing from Carmel due to illness.
