Corona del Mar High picked up where it left off … since the fifth game of the 2012 season.

The Sea Kings reeled off their 27th straight win, shutting out Carlsbad La Costa Canyon, 38-0, in the Under Armour Brothers in Arms Classic opener at San Diego Cathedral Catholic on Friday.

Corona del Mar's winning streak is currently the best in the state, and it stands alone as the sixth longest in Orange County history. The Sea Kings shared the No. 6 spot with Los Alamitos and Mission Viejo. St. Margaret's 44-game winning streak ranks No. 1 in county history.

The last team to beat CdM was Capistrano Valley, coming on Sept. 21, 2012. The Sea Kings (1-0) look for their 28th straight victory on Thursday, when they play host to Dana Hills (0-1) at Davidson Field at 7 p.m. Dana Hills opened the season last week at home with a 20-14 loss to Tustin.

•Peter Bush's debut as CdM's starting quarterback turned out well.

The junior completed his first five passes, including a 15-yard touchdown pass to wide receiver Bo St. Geme 2 minutes into the game. With CdM up, 10-0, Meyer replaced Bush with sophomore Chase Garbers. That was by design.

Coach Scott Meyer planned to give Garbers a look in the offense's third and sixth series. Garbers' first time on the field began a little shaky. Before running a play on first down, on La Costa Canyon's 44 with 4:27 left in the first quarter, the Sea Kings called a timeout. Then the first two plays went for negative yards, before Garbers connected with receiver Dylan Tucker on a five-yard pass.

Bush returned for the fourth series, engineering a six-play, 74-yard scoring drive early in the second quarter. Bush completed each of his three passes, and he capped off the drive with a 12-yard touchdown run up the middle.

"I thought he played great," Meyer said of Bush, who finished 14 of 20 for 176 yards and two touchdowns, and rushed seven times for 21 yards.

Bush is the starting quarterback, but Meyer wants to see what Garbers has to offer.

Garbers, who only threw once, showed Meyer something late in the first half. He rushed for a three-yard touchdown in his second stint. He started the offense's third drive in the third quarter as well.

Garbers might see time in CdM's home opener against Dana Hills.

•Corona del Mar's defense and specials teams looked superb against a CIF San Diego Section Division 1 program.

With 10 starters back, the defensive unit sacked the quarterback four times, picked him off twice, allowed him to complete only 45 percent of his passes, and held La Costa Canyon to 70 rushing yards. Defensive end Parker Chase produced two sacks and outside linebacker Hugh Crance had two interceptions.

On special teams, Daniel Bjurman showed off his foot and toughness.

The senior pinned the Mavericks inside their 10-yard line twice with punts, and booted three of his five touchbacks out of the end zone. When La Costa Canyon returned one of his kickoffs, Bjurman stripped the returner of the ball near midfield and CdM came up with one of its three turnovers.

Brett Greenlee made sure CdM recorded its ninth shutout in the last 27 games. He came off the edge and blocked a 42-yard field-goal attempt early in the fourth quarter.

Jason Neiger converted a 27-yard field midway through the second quarter.

•It took eight carries for tailback Cole Martin to break a long run.

With a new starting offensive line, featuring left tackle Jack Pagliassotti, left guard Joe Anderson, center Bryan Samudro, right guard Arwin Rahmatpanah and right tackle Mitch Dean, the defense held Martin in check in the first half. He rushed seven times for 14 yards.
