A West Hills athlete dominated Saturday in the Arcadia Invitational, but it wasn’t state-leading discus thrower Brenden Song.
Sophomore Melissa Mongiovi, running in the afternoon seeded session, blew out a :55.28, for the overall first-place finish in the Girls’ 400-meter run.  The best the invitational runners could do in  the evening was :56.18.
Song, who increased his state best to 191-5 on Friday in a dual meet with Helix, was fourth in the discus in the evening invitational session with a best of 181-7.
Song trailed Damon Unland of Washington’s Spokane Ferris (190-3), Marty Taylor of Newport Beach Newport Harbor (186-4), and Dylan Fischer of Phoenix Desert Vista (182-7).
Mongiovi now ranks 10th in the country this year and San Diego Section No. 9 all-time. Â She ran in the 2012 state meet and had a best of :55.72 as a freshman.
Carlsbad’s Christian Freeman was ninth in the 3,200 run but his 8:52.65 is eighth all time in San Diego, just below the 8:51.94 by San Diego’s Meb Keflezighi in 1994 and the 8:52.44 by Chula Vista’s Tim Danielson in 1966.
Alex Grigoriev of Rancho Bernardo ran 1:52.71 in the Boys’ 800 and was fifth.
Otay Ranch’s Alexander Law, who went 15-6 in the pole vault on Friday in a dual meet against Bonita Vista improved his season best to 15-9 and won the afternoon competition. Law’s teammate Carina Gillespie was fifth in the invitational 800 in 2:13.
La Costa Canyon’s Emma Abrahamson was 10th in the 3,200 at 10:36.01.
Granite Hills Jake Johnson ran :14.60 in the 110-meter high hurdles and Scripps Ranch’s Brian Thomas circled the 400-meter oval in :49.22.
