Imagine being thiiiiiis close to bowling a perfect 300 game ... only to watch that stupid lane rack thingy come down and BLOCK YOUR BALL on the VERY LAST roll.
That's what happened to Troy Walker, who was killin' it at the 2013 Luci Bonneau Doubles Tournament in Houston this weekend ... and the heart-breaking moment was all caught on tape.
Ya gotta watch the footage ... captured by InsideBowling.com ... and then listen to Walker's explanation.
According to Walker, the whole thing may have been his fault because he hit a reset button on the lane right before his throw -- though Walker says he THOUGHT he was resetting the lane next to his.
Either way, Troy got a do-over on the final shot ... but blew it.
A wise bowling enthusiast probably said it best -- "Sometimes you eat the bar, and sometimes the bar ... well, he eats you."
