Freshman Bryan Dameworth of Agoura and Christy Farrell of Thousand Oaks High turned in the leading performances by Valley-area runners at the Royal cross-country Invitational at Moorpark College on Saturday.
Hart won the boys medium school team championship and Thousand Oaks finished second in the large school division.
Dameworth's victory in the medium-school race was his third straight of the season. His 14:57 effort over the 2.9-mile course was the second fastest of the day. John Williams of Hueneme won the large-school race in 14:48.
Although he is only a freshman, Dameworth was never seriously challenged after the 880-yard mark and finished 100 meters ahead of Hart's Frank Flores, who ran 15:13.
In the girls large school division, Westlake finished second. Thousand Oaks was third.
In other action, Melissa Sutton led Newbury Park to an easy victory in the Woodbridge Invitational at Irvine. Sutton set her second consecutive course record with a time of 17:01, breaking Heather Scobie's mark of 17:39. Scobie, a sophomore at Saugus, finished second in 17:49.
