When Maxwell Dyce was forced to scratch from last week's Ventura County track championships with a twinge in his hamstring, the first feeling was frustration.

Then followed focus.

Then came a remarkable performance in the Marmonte League track and field championships on Friday night at Moorpark High.

The Moorpark High senior scorched his home track and the competition by winning the boys' 100-meter dash in a county-best 10.53 seconds and dominated the boys' 200 in a league-record time of 21.80. For good measure, Dyce won the long jump at 22 feet, 412 inches and placed third in the 110 hurdles.

The son of former Jamaican Olympic sprinter Trevor Dyce said the results were all about focus.

"It was frustrating when I couldn't compete in county," he said. "It actually might have been a blessing in disguise. I was really focused this week on my races. I was definitely looking for my best results."

Dyce left little doubt in his signature races. His sizzling performance in the 100 cinched the race by the 50-meter mark. Second-place Bradley Cicotti crossed the finish line in 11.21.

Dyce's 200-meter record was nearly two seconds better than second-place Cicotti (23.17).

Despite the blazing times, Dyce thinks the best is yet to come — maybe as soon as next week in the CIF-Southern Section Division II prelims.

"I know I can do better," said Dyce, who tuned up in the league prelims with qualifying times of 10.64 in the 100 and 22.0 in the 200. "I can improve my start a lot. I didn't get a great start today."

Dyce's big evening was among several sterling storylines. Royal High sophomore Thomas Garner seemingly announced his arrival as a top-level force in the hurdles by sweeping both the 110 and 300 boys' events.

Garner's personal best in the 110 hurdles (14.83) earned him a tight win over Garrett De Mirjian of Thousand Oaks, who finished in 14.87. His 300 time of 40.66 made him a decisive winner in the longer race.

Garner said he was motivated by a miscue in last week's Ventura County meet when he clipped a hurdle in the 110 and fell out of contention.

"It made me be more focused today," Garner said. "I felt motivated to prove that I belong."

Calabasas senior Brittany Harper continues to prove she ranks among the state's top performers.

After winning the girls' 400 and 800 in the county meet, Harper won the 200 (24.77), 400 (56.36) and 800 (2:18.03) in her last Marmonte League competition.

"Winning a race is always a big deal for me," Harper said. "I wanted to finish league on top."

Both 1,600 races were special duels.

In the boys' race, Clayton Graham of Calabasas outkicked Royal's Travis Edward to win a coveted league crown. Graham crossed in 4:18.82 while Edwards, who won the 1,600 in last week's county championships, finished in 4:19.73.

"It's a huge win for me," said Graham. "My brother (Ian) was always a big role model for me, but he never won a league championship. Now we've got one in the family."

Graham used the final lap to fend off Edwards.

In the girls' 1,600, sophomore Liberty Miller went wire to wire to hold off Erin Baird of Agoura. Miller crossed in 5:08.77 and Baird was second in 5:12.34.

Miller said Baird nearly took the race away by almost pulling even on the third lap.

"I wasn't really confident," Miller said. "But it was a matter of giving all I have, and I really wanted this race. I figured Erin was going to get me in the 3,200, so I wanted to get her in the 1,600."

Sure enough, Baird won the 3,200 in 10.48.92, while Baird was second in 11:19.98.

Other notable boys' winners included Kevin Graf in the shot put (54-10 1/4), Philip Burks in the triple jump (45-3) and Sean Gildea of Thousand Oaks in the 3,200 (9:28.96).

Besides placing second in both hurdles, Thousand Oaks' De Mirjian won the high jump at 6-4 and was third in the long jump.

For the girls, Ravan Chavanne of Newbury Park won the 100 in 12.36, Calyx Schentrup of Thousand Oaks won the long jump in 17-0 3/4, and Taryn Kurz of Agoura won the 300 hurdles in 45.51.
