The Oxley team of Dominic Mercer, Joe Slowiaczec and Josh Twee, who are all turning 15 this year, went into Saturday's final round as the top seed after performing well in the preliminary rounds the previous week.

The team was expected to breeze through its early matches on Saturday, before facing its toughest tests in the semi-finals, but that wasn't to be the case.

Oxley still managed to win its first three match ups, but all of them had to be decided in eight bouts, with Oxley winning 5-3 on each occasion.

"Those easier teams ended up being harder than the final two bouts themselves," Mercer said.

"They weren't harder, we just weren't fencing that well," Slowiaczec added.

But the Oxley team found its best form when it really mattered, beating Sydney Grammar 5-0 in the semi, before thrashing the highly fancied Hills Grammar outfit by the same score in the gold medal game.

The Oxley boys were just happy to make the final and according to the team that's why they were able to perform so well when the pressure was on.

"I think we wouldn't have won if we thought second place wasn't good enough," Twee said.

"We were very happy with second place, so we just went out there trying not to get completely thrashed by them and we did quite the opposite.," Mercer said.

"Their worst fencer is ranked second in under 15s in NSW and they're two better fencers are in the top five in NSW under 17s."

The Oxley team returns to Newington this Saturday for an invitational tournament, which along with the State Championships helps decide who will progress to the national championships in Auburn in July.

After their State title success, Oxley should be one of the team's selected, especially if they have another good showing this weekend.

This year was the third time the boys have competed as a team in the State Championships and their second in the senior age group, which is usually dominated by year 12 students.
