Gilman's game plan against Boys' Latin was simple: dig in defensively and match the intensity of the Lakers' talented midfield.
"Their midfielders are their strength, so we really keyed on them and slid early," said senior defender Tap Kolkin. "We kind of packed it in defensively. We confused them and made them to take bad shots."
And the No. 3 Greyhounds simply executed for a nondivisional 5-3 victory that ended an eight-game winning streak by the defending Maryland Interscholastic Athletic Association A Conference lacrosse champion.
The win was the 100th of coach Dave Allan's Gilman career.
Though the top-ranked Lakers (4-1) led 3-2 at halftime on goals from David Melara, Greg Baggin and Drew Peace, they had a tough time from the outset and went scoreless in the second half against Kolkin, David Baker, All-Metro player Gentry Fitzpatrick and goalie Grant Zimmerman (16 saves).
Zimmerman, who intercepted several passes as an All-Metro football defensive back, similarly picked off 11 of the Lakers' first 15 shots - including three of their first four and six of their first eight.
Gilman (2-0) was generally relentless. Kolkin and Dave Caperna combined to check five balls from opposing sticks, and between them they scooped seven ground balls. John Corbin and Anthony Triplin stripped two balls each - the latter doing so once in the third period when Gilman was down a man.
Peter McCormick, Brannon Knott and Davis Lindsey wreaked havoc defensively.
"They pressed out a little bit on us in the third quarter, and we failed to clear the ball, like, six times," said Lakers coach Bob Shriver. "They took us out of the game a little bit and we never got into a flow."
After scoring the game's initial goal, Gilman's Luke Wilson, a second-team All-Metro attackman, had just one assist while being guarded by All-Metro player J.R. Stahl.
But Gilman's midfield took over. Junior midfielder Zack Goldberg scored twice, each time digging ground balls, roll-dodging defenders and firing 12-yard shots past All-Metro keeper Trey Sheain (11 saves). Senior midfielders Corbin and Chris Merwin scored Gilman's third and fourth goals off wicked shots.
With 2:09 left in the third period, Corbin slipped his tying volley, off a pass from freshman Brian Carroll, inside the post past Sheain's right ankle. And with 7:05 to play, Merwin outran his defender from behind and to the right of Sheain, ripping his waist-high shot into the net's opposite side.
Goldberg's initial goal tied the score at 2 with 3:17 left in the first half, and his second gave Gilman its winning margin with 2:28 to play.
"I don't think they expected much from our middies," Goldberg said. "They gave us a lot of space."
