With his 14:48.26 in the 1650 free earlier this month, Mulgrew ranks fourth in the 15-16 NAG rankings and second in his class behind Luke Ellis (14:29.48).
While the 500 freestylers stole the show on night 3 of the Huntington Beach Sectionals, there were a number of other big swims to highlight the session.
Mulgrew has dropped over forty seconds in the race over the last year and dropped over 17 seconds off of his previous best which he swam just last week.
