Wilhelm holds the Laguna single-season (12) and career (24) records for victories.
"Any time you can throw a complete game and get a shutout in CIF, you've had a pretty good game," Bair said. "Grant was awesome out there. They got some hits off him, but we were able to keep them from scoring."
Wilhelm also figured prominently in Laguna's offense. He went two for four and it was his first hit, a one-out, two-run single with the bases loaded in the bottom of the third, that allowed Laguna to pull out to a 3-0 lead. He lined a 2-2 pitcher over the head of Nordhoff third baseman Luke Boyd into left field. It brought in Cochran, who had reached base on a fielder's choice, from third, and also Nunis who hustled in from second base for the Breakers' third run.
It was part of the six-run inning for Laguna which went into a comfortable lead.
Following Wilhelm's single, Will McInerny hit an opposite field single to right field to load the bases. Designated hitter Garrett Burk then singled to center to score Steven Harrison from third. With bases loaded and two out, Jack Simon ripped a shot into left field that got under the glove of Baylee Rogers and rolled toward the fence. The sophomore ended up with a double that cleared the bases, and the Breakers suddenly had a 7-0 lead.
Simon's big day at the plate continued in the bottom of the fifth when his fly out to right field completed the scoring by bringing in Burk who had singled for the second time in the game.
"It felt good to score some runs," said Bair, whose team entered the postseason averaging 10 runs per game. "We had some clutch hits at the right time. This is a game of momentum and in the fourth, we stomped on the gas."
Laguna took a 1-0 lead in its first at-bat. Lead-off hitter GrandPre reached base on an infield error, stole second and was moved to third on an infield groundout by Cochran. Nunis then sent a shot high off the screen in left field for a double that scored GrandPre from third.
The Rangers (13-9) also committed four errors in the field.
Two impressive postseason wins has Laguna playing again Friday because the Breakers continue to keep their eye on their main goal.
"It was a good win and a great way to start the playoffs," Bair said of the Nordhoff game. "This team believes it can make a good run in CIF. As a team, we talked about winning innings. So far, we are winning innings."
Bair said that Wilhelm will start Friday at Sonora.
The winner of the Laguna-Sonora game moves on to the division semifinals at 3:15 p.m. Tuesday and will face either Valle Vista League champion and third-ranked San Dimas, or Pioneer League runner-up and fourth-ranked Torrance who square off in another quarterfinal game Friday.
The Division 4 championship game is at 7:30 p.m. June 7 at UC Riverside.
