During the match, he said exactly that. He also said that he had another ball to go to once it started to carry down. Never pulled the trigger on that move though.
Now Ciminelli is sitting at home wondering what would have happened if he made the switch. If you are thinking "I might need to make an adjustment here" do it, take the chance more than likely you are right, if not it is only one frame lost and you will know better where you need to move to to make the ball you were using work or to make the ball change from a deeper part of the lane.
Bowling on modern conditions with modern equipment is all about making adjustments and knowing when to make them. Knowing this is what give you the confidence you need to perform at a high level, being right 75% of the time allows you to perform at the highest level. The winner on tour is usually the guy who guesses right and makes the changes when they need to be made. Once in a long while the lanes and conditions will be just right for only you and your favorite ball, it does happen, but it is rare. It happened to me once I threw a 788 and threw three good shots it seemed, but I could do no wrong, and got a nice trophy for it, people win the lottery too.
