Missed it by that much: Bowler's perfect game sabotaged by technology US bowler Troy Walker was one strike away from hitting a rare 300 when the unthinkable happens. Courtesy insidebowling MStruck out: The gate comes down and blocks Troy Walker's final bowl. SCORING 300 in tenpin bowling is a rare, rare feat. It's 11 strikes ina row - the perfect score. It's Nadia Comenici and her 10s in gymnastics at the 1976 Olympics. Or Steve Davis scoring a 147 break in snooker. So, you can imagine Troy Walker would be a tiny bit miffed to miss out on a perfect 300 when he was bowling in Houston at the weekend. Especially when you consider HOW he missed out on the perfect game. Computer. Says. Walker had just sent his final bowl down the lane when disaster struck. He needed a strike to hit 300. And the ball was looking good, but ... Inexplicably, just as it was about to hit the pins ... the rack came down, blocking the ball before it could mow down the pins. Walker got one last shot at 300, but only knocked down seven pins on his last try, finishing with a 297. He took it all very well. "That was odd," he said in a post-game interview. Something to talk about, won't forget that one.
