SWIMMING AND DIVING

* Southern Section Girls’ Relays, Long Beach Belmont Plaza Pool, 7 p.m. Saturday: Although many of the county’s top girls will be away at either Senior or Junior Nationals, the meet still promises to produce some of the season’s top times. With top-ranked Irvine and No. 2 Laguna Hills without their best swimmers, it could be a wide-open race for the title.
