All it took was one play for No. 11 Wilcox to establish dominance.

The Chargers had won their last three games by a combined total of 85 points. Things had been going well for Wilcox.

It couldn’t have started out any better on Friday night against Sacred Heart Prep. Opening their first drive on the 30-yard line, the Chargers snapped the ball to quarterback Kai Imahara, who faked an option handoff and bolted around the left side.

Seventy yards of swift running later, Wilcox had a seven-point lead. Imahara’s long sprint set the tone for the rest of the matchup, which the Chargers won 35-7.

“It is nice when you score on the first play,” Wilcox coach Paul Rosa said. “It gets your guys going. Our quarterback made a good read and popped one.”

Next up for Wilcox is a date on Friday at Los Gatos. The two powers in the Peninsula Athletic League Bay have been on a collision course — both teams are 3-0 in league play and have been dominating Bay Division opponents left and right.

No. 1 De La Salle 42, No. 20 Monte Vista 7 >> De La Salle built a 28-point halftime cushion, widened the margin to 35-0 in the third quarter and cruised at home over Monte Vista. Quarterback Toa Faavae ran for two touchdowns and passed for one to lead the Spartans, who improved to 8-0. Monte Vista fell to 5-3.

No. 2 Pittsburg 47, No. 14 Liberty 15 >> For a moment, Liberty looked as if it would give Pittsburg a real scare. But that didn’t last long as the Pirates ran away with this one en route to their 27th straight Bay Valley Athletic League win. Liberty went up nine in the second quarter, but Pittsburg responded by scoring 41 consecutive points by the end of the third. Quarterback Marley Alcantara completed 20 of 26 passes for 248 yards and four touchdowns.

No. 3 St. Francis 49, Sacred Heart Cathedral 24 >> St. Francis moved into sole possession of first place in the West Catholic Athletic League. Kingston Keanaaina had another big game for St. Francis (7-1, 5-0), scoring three all-purpose touchdowns: a 76-yard run, a 68-yard run and an 81-yard kickoff return. He added a 51-yard punt return for good measure.

No. 4 San Ramon Valley 29, No. 22 Amador Valley 28 >> Rhett Thompson threw for a touchdown and two-point conversion with less than three minutes left in the fourth quarter that put San Ramon Valley ahead 29-22, then Henry Ellis intercepted a two-point conversion attempt by the visiting Dons in the final 20 seconds to preserve a one-point win. The Wolves (8-1, 2-0 EBAL Mountain) were trying to bounce back from a 42-14 thrashing by De La Salle last week.

No. 5 St. Ignatius 20, No. 7 Valley Christian 13 >> Second-half St. Ignatius made its celebrated return this week in San Francisco. Down 13-3 at the half, the Wildcats (6-2, 4-1 WCAL) relied on their patented comeback to score 17 unanswered and get a huge WCAL win. Jarious Hogan’s 4-yard rushing TD gave the Wildcats the lead with 4:18 to play, and SI sealed it with Hicks’ interception inside the SI 10 with less than a minute to play.

No. 6 Los Gatos 38, Menlo School 0 >> The Wildcats blanked Menlo at home. Scotty Brennan completed 5 of 10 passes for 126 yards and a 4-yard TD toss to Max Thomas. Callum Schweitzer completed 2 of 5 throws for 73 yards and two scores, including his own 4-yard TD toss to Thomas.

No. 8 Serra 47, Bellarmine 6 >> Legendary Serra coach Patrick Walsh won his 200th game as the Padres cruised over winless Bellarmine in WCAL play at San Jose City College. Nano Latu rushed for 142 yards and four touchdowns to lead the way.

No. 12 Archbishop Riordan 42, Archbishop Mitty 13 >> Cynai Thomas caught a pair of spectacular touchdowns from Vanderbilt commit Mike Mitchelll Jr. in Riordan’s WCAL victory over Mitty at Foothill College. Adonyae Brown also ran for a score. Mitchell accounted for Riordan’s five other touchdowns.

No. 13 Clayton Valley 20, Campolindo 12 >> Backed up on its 1-yard line after getting a stop, Clayton Valley got Campolindo to jump offsides twice before Hayezon Jackson ran for an 89-yard touchdown. Myles Tugbenyoh rushed for another CVC score, and Javale Jones also threw a touchdown to Zion Jones in the DAL Foothill showdown. Campolindo’s Joe Revelos caught 12 passes for 110 yards.

No. 15 Bishop O’Dowd 35, Moreau Catholic 9 >> O’Dowd’s won its fourth in a row and its sixth of the season, matching its total from last season, as the Dragons moved closer to capturing the WACC Foothill Division title. O’Dowd outscored Moreau 21-0 in the second half as they rolled in a matchup between teams that had not lost in league play. Devin Wilson led an efficient offense with 135 yards and two TDs on 11-of-17 passing.

No. 16 Menlo-Atherton 27, Palo Alto 13 >> Xander Eschelman threw an 80-yard post pass to JT Roeder on the first play of the game and M-A never trailed in the PAL Bay Division win. Palo Alto tied it 6-6 on a 46-yard Justin Fung-to-Jeremiah Fung scoring pass, but the Bears regained the lead on a swing pass from Eschelman to Teddy Dacey and made it 20-6 on a 1-yard run by Torin Barger.

No. 23 Santa Teresa 44, Leigh 34 >> Brenton Gaches accounted for four touchdowns, rushing for two and tossing scores to AJ Rangel (40 yards) and Jamison Azzarello (37 yards) to lead Santa Teresa in BVAL Mt. Hamilton play. Santa Teresa is 7-1 and nipping at Christopher’s heels with a 3-1 record in the Mt. Hamilton.

No. 24 Willow Glen 56, Prospect 0 >> The Rams scored four rushing touchdowns, passed for three and had a pick-6 while cruising to their eighth win in a row. The 8-0 start is Willow Glen’s best since MaxPreps began keeping records 21 seasons ago. The Rams are 3-0 in the Santa Teresa Valley Division, tied for first with Leland. Quarterback Aiden Akery completed eight of 10 passes for 118 yards and two touchdowns.

San Mateo 30, No. 25 Half Moon Bay 20 >> Cameron Palma rushed for 112 yards on 15 carries and threw two touchdown passes to lead the Bearcats to a home victory over Half Moon Bay in a PAL Ocean Division game. The result creates a showdown with Sequoia (3-0 in league) Friday for at least a share of the division title.

Gunn 41, MacDonald 13 >> Sam Dellenbach returned two kickoffs for touchdowns, Luke Hines scored on runs of 63 and 52 yards and Andre Lee ripped off a 46-yard scoring run as Gunn (8-0, 6-0) rolled to a victory at home in PAL Lake Division play.

James Logan 34, San Leandro 22 >> Lamar Ellis’ 1-yard run and Jose Rodriguez’s extra point with three minutes left to play gave the Colts some breathing room in the hard-fought contest.
