When Glenelg’s players convened on the sideline for halftime of Friday night’s showdown against Marriotts Ridge, the Gladiators’ coaches had little to say.

After a few quick words, Coach Nicole Trunzo and assistant Alex Pagnotta stepped aside, and the players formed their own huddle. Senior goalkeeper Maddie McSally called for the defenders to continue their aggressiveness when the Mustangs tried to feed players in the circle. Other players complimented one another and commended the offense for building a 9-3 lead against their rivals.

Such is the sight during most Glenelg halftimes. The coaches look on with trust that their players, the two-time defending Maryland 3A/2A state champions, have the determination and intelligence to guide themselves through any adjustments that need to be made.

“Of course the coaches can see from the sideline, but we as players see from the field,” said McSally, a Maryland commitment. “We may see something that the coaches don’t and, from our perspective, we can say what their offense is doing, or maybe the offensive captains can say what their defense is doing.”

Glenelg hasn’t had much to fix this season. Aside from Friday’s 15-10 win over Marriotts Ridge, the Gladiators have outscored three other Howard County opponents, 60-7. Despite close losses to Notre Dame Prep and No. 2 St. Stephen’s/St. Agnes, Glenelg, which returns to the top three in this week’s rankings, has dominated public-school competition.

Despite Marriotts Ridge finding a way to dominate draws and possession throughout Friday’s contest, the Gladiators used efficient shooting and quick strikes in transition to take the county lead. Throughout the second half, they used a methodical approach on offense as the Mustangs posted a 6-1 run and threatened a comeback. In the final 10 minutes, Pagnotta instructed his midfielders to hold the ball until a defender brought pressure. Then, he’d often yell, “Freelance!” — a set that Glenelg runs, but one that allows his players some freedom to find open looks.

“The girls just move the ball and work together,” Trunzo said. “And whoever finishes, finishes.”
