GIRLS’ RECAP

Three future Division I college swimmers were the stars of the meet, with each winning two events.

Grace Rabb of Dripping Springs High School, who has signed with Florida, broke a 17-year-old state record by winning the 200 IM in a time of 1:56.40. The old record was 1:56.56 set in 2008 by Mary Beck of Austin Westlake.
