This race was all Femke Heemskerk. The Dutch swimmer, who owns the world-leading time in this event this year, was out fast and never looked back, posting a solid 1:55.68 for the win. She now owns the 1st and 3rd fastest times in the world. 2nd place went to Katinka Hosszu in her first big race of the night, and Missy Franklin kicked off her night with a 1:57.02 to take third. That ranks Franklin 12th in the world, the 2nd fastest American behind Katie Ledecky.
Allison Schmitt touched in 4th (1:57.29), and Elizabeth Pelton was 5th in 1:58.30.
The B final was a hotly contested race in the middle of the pool, as Maya DiRado led most of the way. However, distance-oriented Cierra Runge held her speed through the final 50 and edged DiRado to the wall, posting a winning time of 1:59.50. DiRado was 2nd in 1:59.61 followed by Kennedy Goss in 2:00.11.
