It was as if a welcome mat had been placed at the foot of the crease and all Syosset shooters were invited inside.

The Braves had no trouble maneuvering for close-range shots and they capitalized with an overwhelming offensive performance, pounding MacArthur, 17-4, Tuesday night in a Nassau Class A boys lacrosse quarterfinal at Hofstra's Shuart Stadium.

"Their slide wasn't there and we exploited," said Jon Camposa, who led No. 2 seed Syosset (12-4) with four goals and an assist. "Once we get it going, no one can stop us."

Certainly No. 7 MacArthur (7-9) couldn't prevent Syosset from advancing to next Wednesday's semifinal against Baldwin at Hofstra.

"It's the most complete game we've played all year," said Camposa, who scored all four of his goals in the second half.

"He was the man tonight," Syosset coach John Calabria said of Camposa, but the senior midfielder had plenty of help.

Ryan Hunter had three goals and Andrew Keith, John Diaz, Frankie Buffalino and Alex Hatzopoulos two each. Diaz and Keith also contributed two assists each as the game reached ''running time'' status once Syosset built a 12-goal lead late in the third.

"It felt so good," Camposa said. "This is the first time all year we were able to spread it around like that."

For the Braves, even as a thick fog descended onto the playing field, the path to the goal was crystal clear all game long.
