TOKYO (AP) — United States swimmer Caeleb Dressel watched his Olympic record fall in the 100-meter butterfly, only to take it right back.

Minutes after Hungary’s Kristof Milak took down the mark in the first semifinal heat, Dressel went even faster with a time of 49.71 seconds in the second heat.

Dressel will be a big favorite in Saturday morning’s final, though he could get pushed by Milak.

Also in the pool, South Africa’s Tatjana Schoenmaker set the first individual swimming world record at the Tokyo Olympics, capturing the women’s 200-meter breaststroke with a time of 2 minutes, 18.95 seconds.

American Lilly King set a blistering pace early in the race and held on for a silver in 2:19.92. Teammate Annie Lazor grabbed bronze in 2:20.84.
