Flickinger also moved to 18th all-time in the world rankings behind Susie O’Neill (2:05.81) of Australia and just ahead of American Misty Hyman (2:05.88).

Flickinger will attempt to win a national championship in the 200 fly final at 9 p.m. Wednesday She is the defending champion in the event and would have to be considered a strong favorite to win the race.

The second-place finisher in the preliminary action was Stanford’s Katie Drabot at 2:07.30, which was nearly a second and a half behind Flickinger’s preliminary time.
