The Cannons’ all-time leading scorer finished with a game-high five goals Saturday night as Boston forced the expansion Charlotte Hounds to wait another week for their first win. The 20-12 victory came before 9,273 at Harvard Stadium.

“It was good to get back out there,’’ said Poskay, who led the Cannons with 30 goals last season. “To be honest, [scoring on the first possession] was a nice way to get into the game as fast as possible and I just rolled from there.’’

Charlotte continued to hang around until Boston’s nine-goal third quarter, when the Cannons took advantage of a planned goalie switch. The Hounds replaced Joe Marra, who stopped 8 of 15 shots in the first half, with Adam Ghitelman to start the third period.

Ghitelman stopped just two of 11 shots in the third and Boston entered the final quarter leading, 16-9.

“We weren’t getting into our offense, or we were getting into our offense late into the shot clock,’’ said Cannons first-year coach Steve Duffy, whose club improved to 2-0. “We were just pressing a little bit and we talked about not doing that at halftime and I think that we had some success in the second half.

“The great thing about our guys is that they listen, they want to win, they want to play hard, and they want to be coached.’’

Cannons goalkeeper Jordan Burke, who set a MLL record last weekend by limiting Rochester to three goals, turned away 14 of 26 shots.

Chris Eck took advantage of the Hounds’ struggling faceoff game (Charlotte won just 12 of 32 last week), winning 23 of 36 draws.

Brian Farrell put the Cannons up by two 2 1/2 minutes into the game. The Hounds rebounded to score the next two goals as Justin Smith’s transition strike tied the game with 6:54 left in the first.

Goals from Ryan Boyle and Michael Stone sent the Cannons into the second quarter leading, 4-2.

Poskay was responsible for two of the Cannons’ second-period goals, finding weak spots in the defense to register his hat trick with 7:05 left in the half. Poskay scored twice more in the third quarter.

Ghitelman continued to struggle in the final frame, allowing four more goals, including one from Waltham native Jon Hayes.

“I’m very happy with our offensive production,’’ said Duffy, whose team has scored 35 goals in two games, “but we’ve still got some work to do.’’
