Craig Whittle of St. John's is $188,000 richer, after winning the largest Pro-Line prize ever awarded in Atlantic Canada.

The total prize was from betting on four underdog teams in the National Basketball Association, all in the same day on Feb. 13.

"I follow sports a fair bit and it's just … some games were hot and some games were cold," Whittle said.

"It just keeps it interesting."

He made two separate $25 bets, netting $81,156 and $107,187, hoping Denver would win against league-leading Golden State.

"The Denver pick was largely based on Golden State coming off an emotional game against Oklahoma City two nights previously," said Whittle.

"Many sports betters refer to such match-ups as a 'let-down spot.'"

Whittle already has a vacation booked for himself, his wife and daughter, and both sets of grandparents.

In November, Whittle also won a $12,000 Pro-Line prize, and has had other smaller wins over the years.
