If Erin Barry seemed exhausted after Manhasset’s 45-39 win over Garden City in the Nassau A1 opener, it was for good reason.

The senior played all 32 minutes for the host team last night, and not a single second of her time on the court was spent standing still.

If you blinked, you missed her. Barry was a blur, weaving, diving and creating for her teammates. She finished with 11 points, seven rebounds, six steals and five assists.

“She never asks for a break,” coach Lauren Sadeh said. “She probably would get angry if I took her out of the game.”

Barry had no choice but to keep moving thanks to Garden City’s up-tempo offense. The Trojans inbounded the ball and immediately began a sprint toward half-court, keeping the Indians on their toes.

That’s how Garden City was able to end the first half with only a four-point deficit at 24-20 after trailing 18-8 following the conclusion of the first. With point guard Michaela Bruno (12 points) running the offense, Garden City created quick opportunities for shooters Kerry McCarraher (nine) and Kelly George (six).

Manhasset’s Leah Ritterband (seven) opened the third quarter with a three-pointer, but Garden City scored six straight to bring the deficit to one point at 27-26.

The Indians finished the quarter with four unanswered to lead 31-26, but the game was still too close for Chloe Murphy’s liking. Murphy finished with a game-high 14 points and three blocks thanks to aggressive play in the low-post.

“I was more aggressive toward the end,” she said. “When you see them catching up, you want to drive and be more aggressive.”

Bruno scored the fourth quarter’s opening basket to make the score 31-28, but Garden City went on a 7-0 run over the next minute and a half, effectively putting the game out of reach at 38-28. Barry was key in locking down the perimeter during the run. “Being in [A1] this year, we have a tough schedule,” Sadeh said. “We don’t take any of these games for granted.”

Manhasset next plays at Elmont on Friday at 4:30 p.m.
