It was a gritty, grind-it-out kind of game, with goals at a premium. Neither defense was leaky, but South Side had a Leake that Carey could not plug.

Mike Leake scored four goals as South Side held off Carey, 6-4, in a Nassau Class B boys lacrosse quarterfinal at Hofstra’s Shuart Stadium Friday night. Two of those goals came on assists from Leake’s best friend, Ryan Langdon, who added two goals as the Cyclones (11-6) advanced to Wednesday’s semifinal against Garden City at Hofstra at 8 p.m.

“We have a lot of chemistry,” Leake said. “We kept getting the back door. I’d wait for the defenseman to turn his head and then cut to the cage where Ryan would find me.”

The L & L tandem helped South Side overcome a scoreless first quarter and erase a 2-0 deficit. Leake scored the Cyclones’ first goal after picking up a loose ball in front and burying it. Langdon did the same thing a minute later to tie it.

Leake scored the next three goals — in transition on a feed from Peter Malizia and two quick-stick finishes on passes from behind the cage by Langdon, who scored unassisted midway through the third quarter to give South Side a 6-2 lead.

Carey made it interesting with fourth-quarter goals from Matthew Stevens and Mike Kadnar, an all-county player last year who played his first game of the season after sitting out with an injury. Kadnar scored with 5:28 left, but South Side’s defense prevented the Seahawks (8-9) from getting any more scoring opportunities down the stretch.

Even though the Cyclones took only 19 shots, Leake made the most of his, especially in the slot. “I do it a little differently in front. I like to finish quicker than some players,” Leake said. “I’m not a big fakes guy.”

But he and Langdon have developed into big finishers, combing for 51 goals. “The both started last year as sophomores,” South Side coach Steve DiPietro said. “They’re unselfish and they move without the ball. They’ve got a good connection.”

Garden City advances.

Those post-practice shooting sessions are paying off.

Garden City extended its winning streak to nine with a 16-4 victory over North Shore in the first game of a Nassau B quarterfinal doubleheader at Hofstra.

“Every day after practice, for 30 minutes, we’ve been working on our shooting accuracy,” said Jamie Atkinson, who scored four goals as did Kyle Steinbach.

Garden City was remarkably efficient, putting 22 of 28 shots on goal. The Trojans scored the game’s first six goals, led 8-1 at halftime and scored the first five goals of the third quarter. J.P. Basile also had a big game with two goals and three assists for the Trojans, who scored many of their goals on the fast break, a departure from previous years when Garden City preferred a more settled offensive style.

“We look to push it in transition a lot more,” Atkinson said. “Our offensive is clicking now.”
