Troy Walker's Bid For Perfect 300 Bowling Game Ruined By Mechanical Pinsetter (VIDEO)

This try for a bowling score of 300 ended with heartbreak to spare.

Bowler Troy Walker was one strike away from a perfect game when the mechanical pin sweeper came down and blocked the ball on his final roll, video from InsideBowling shows.

Walker was given another try, but left three pins standing for a score of 297 -- still the highest score at last weekend's tournament at Palace Lanes in Houston.

Walker told InsideBowling that it was probably his fault because he pressed the reset button for the lane next to him -- but his lane was reset instead. "Something to talk about," he said in the video, referring to his hard luck. "Won't forget that one."

Walker's chances of actually completing a 300 aren't so hot, according to Yahoo! Sports. The site noted that even a bowler who averages a record seven strikes per game has a mere 1 percent chance of getting a perfect score.

And not to make Walker feel bad, but there are those for whom a 300 is as easy as 1-2-3. In April, Joe Scarborough of Charlotte, N.C., bowled three 300 games in a row, marking the first 900 series in the history of the Professional Bowlers Association.
