Between powerhouses Anglo-Chinese Junior College (ACJC) and Raffles Institution (RI), the two schools have dominated the lanes by winning four overall titles each at the Schools National A Division Bowling Championships over the past four years.

But on Tuesday afternoon, Millennia Institute's (MI) Isabelle Lee, a third-year student, caused a stir at Orchid Country Club when she clinched her school's first ever all events girls gold.

"I'm quite happy, because it was quite a shock," she said. Despite her lead after yesterday's team event, Isabelle never thought to rest on her laurels. "Today was the toughest. Though I was leading, there's still the worry that others could catch up."

Isabelle, 18, added that she hopes her win will spur her fellow MI bowlers to gun for more silverware.

However, the loudest cheers of the day erupted the moment ACJC confirmed its double gold for its boys and girls teams. After a gruelling fight, ACJC reclaimed the boys overall title from defending champions RI, and took the girls overall title for the third consecutive year.

ACJC boys' captain Benjamin Quek said: "This is something we set out to do since day one. We put in so much work, so much effort, so much everything. We are finally here. I am so grateful.

"The reason why we did so well is because we do it for the school. Personal glory always comes after school glory."
