PBA (Professional Bowlers Association) bowler Ronnie Russell was competing in the semi-final of the PBA Chameleon Championship on December 28, 2014, where he eventually went 12 for 12 on strikes to end up with a perfect 300 game.
There were some iffy spots (7, 8 and 9 come to mind), but the closest call came on his 11th throw where it looked like 1 pin might stand, that is until another pin luckily rolled over to knock it down in the corner.
This was the 24th time in history where a bowler bowled a perfect game in a televised match. Russell went on to the finals where he would face the eventual winner D.J. Archer, losing by a score of 241-215.
For those who don’t know how bowling is scored, the highest possible score for a player is 300 by bowling 12 strikes in a row in a single game. A strike counts as 10 plus any pins that fall in the next two rolls. There are 10 frames in total, one strike coming in each of the first nine frames, and then three more in the tenth frame.
As you can see, the maximum score in any frame is 30 (10 for first strike, another 10 for a strike on your next roll, and another 10 for a strike on your second roll). 30 x 10 = 300!
