World Cup Westmont – Day Three Finals: Lani Pallister Pops Aussie Record in 1500 Freestyle; Becomes No. 2 Performer in History<\/strong><\/p>\n

Just one session remains of the World Cup stop in Westmont, and if the opening days of action are any indication, the evening should provide some dazzling performances. Already, Regan Smith has equaled her world record in the 100-meter backstroke and set an American record in the 200 butterfly. Meanwhile, Australia’s Mollie O’Callaghan destroyed the world record in the 200 freestyle.<\/p>\n

On Sunday night, Smith will return to the pool for a duel with Aussie Kaylee McKeown in the 200 backstroke while O’Callaghan will chase a title in the 100 freestyle. Gretchen Walsh (100 butterfly) and Luke Hobson (200 freestyle) will contest events in which they own the world record and Canadian Ilya Kharun will chase his latest World Cup victory, this time as the top seed in the 200 butterfly.<\/p>\n
