My 2 cents:
I believe Lonny threw that washout with the Ebonite ball, when he had been using the Raging Inferno on that lane. Now, I don't know how balls he threw on that lane with the Ebonite ball (Stinger?), but I'd guess he was trying to play a safe shot and just pulled it into the oil too much. I think it was more of a bad guess on his part than a choke shot. He has been out there too long and has already bowled too many great games under pressure for anyone with any knowledge of the game or the PBA to say he choked.
Walter Ray shook his head more in disbelief, because he knew he had already lost; the odds of that happening again are too high to calculate. We all have won games that way, but how often? Not very.
