Silver Spring’s UnbeWiivables successfully defended their title Tuesday at the National Senior League’s Wii bowling championships in Denver.

The three seniors and one staff member from the Margaret Schweinhaut Senior Center won by 280 pins despite missing their two best players and going up against the NSL’s Wii Bowler of the Year.

The team — Bing Cheung, Susan Cheung, Anh Nguyen and Karen Maxin — was on a plane Wednesday afternoon, headed back to Silver Spring with trophy in hand.

“Everybody stepped up,” said NSL founder Dennis Berkholtz, including last-minute addition Maxin, a center employee who is the team’s official coach.

Maxin “bowled well,” Berkholtz said. Bing Cheung “took charge.”

The UnbeWiivables also benefited from the collapse of their rivals, the Happy Strikers of the Active Life senior center in LaGrange, Ga. This year, the Happy Strikers lineup included Vestal Thomas, the NSL bowler of the year, who going into the championship match had just finished 36 straight perfect games. But the streak ended in Denver before a crowd of about 100 spectators. (The crowd was bolstered by the fact that lunch tables were set up by the Wii bowling lanes, Berkholtz noted.)

“No one understands the pressure,” Berkholtz said. “The lights. The people walking around. They are out of their environment.”
