Caeleb Dressel obliterated the world record in the 100 IM at Monday’s ISL Semifinal 2, going 49.88 in the 100 individual medley.

The world record had been Vlad Morozov’s 50.26, the Russian with a stranglehold on the top 10 times in history before the ISL season began. Dressel’s American record had been 50.48, set in ISL Match 10, then the seventh-fastest in history. Morozov’s record dates to Sept. 28, 2018, set in Eindhoven, Netherlands.

Tuesday, Dressel just left the pack behind from the get-go. He went out in 22.79, then came back in 27.09.

Dressel’s world record is the third of the second season if ISL, joining Kira Toussaint in the 50 backstroke and London Roar teammate Adam Peaty in the 100 breast, both from Semifinal 1.

To boot, Dressel jackpotted all but teammate Marcin Cieslak, tallying 30 points for the largest jackpot of the ISL season. The Condors took all 37 points in the event to extend their lead.

Earlier in the session, Caeleb Dressel trimmed .02 off his American record in the 100 free, lowering it to 45.20.

Dressel had been 45.22 in last year’s ISL Grand Final. That he’s already quicker in the semifinal this season is an indication that he could be in position for a big Grand Final in season 2. He could chase Amaury Leveaux’s world record in the event, 44.94 set in 2008. It’s the second-oldest men’s short-course world record on the books.

Dressel went out in 21.86 and came back in 23.34. He controlled the race start to finish in a 1-2 for the Cali Condors with Justin Ress and added 12 points via the jackpot for the leading Condors.

Dressel also went 22.04 in the 50 fly to take second place. That’s a third American record of the session, trimming .02 off the mark he set at the 2019 Grand Final then tied in Match 10 this season (22.06). Dressel was second in that race to Nicholas Santos, who went 21.80 in scaring his world record (21.75).
