Former Cal star Dana Vollmer breezed into Sunday night’s final of the 100-meter butterfly, winning her semifinal heat Saturday night at London.
Vollmer, who set American and Olympic records in her first-round heat, touched in 56.36 seconds in the semifinals — fastest time of either heat.
In the finals, she will duel Sweden’s world-recordholder Sarah Sjostrom, who won the other semifinal heat. Also in the final is American Claire Donahue.
Meanwhile, Ca’s Caitlin Leverenz finished in a tie for sixth in the 400 IM final, touching at 4:35.39, same as Stephanie Rice of Australia. Rice also lost her world record Saturday, snatched away by winner Ye Shiwen of China in a blistering time of 4:28.43.
