I saw the game last and although Dice K on balance pitched extremely well, in the inning where the Jays got 2 runs on him he lost his cool as a result of a very bad call. He threw a pitch that was very clearly a strike which was called a ball, and he sort of childishly snapped his head at the umpire in disbelief. After that call, he suddenly became wild (including throwing a wild pitch that missed Varitek by 2 feet) and the 2 runs later scored that inning. He recovered the following inning but the damage was done. He'll need to be a lot mentally tougher than that in the future, whether it's a bad call, a home run or whatever. You just can't lose focus like that and if you do, you will get eaten up at this level.
His body language after the bad call reminded me of the body language of a woman I defeated in the semifinals of a 64 player ping pong tournament in Cancun in 2000. When you get to the semifinals of a tournament like this, all the players are real good and little things make the difference between winning and losing. In that semifinal match, I was losing very badly - like 11-2 - but 2 things happened that turned the match into a rout in my favor. First, I began to get my timing on returning her serve which was a one-speed topspin serve. Second, as the match went on I noticed that her reaction time on her backhand side, when challenged there with quick returns, was not good. After I caught her with two lightning returns backhand side which she netted, she had the exact same reaction as Dice-K did to the bad call, and she also slammed her racket on the table and swore in French. Right then, even though I was still losing in the match about 11-4, I said to myself "she is fucking dead meat." I then reeled off a long run, attacking her backhand side. She could not make the necessary adjustments and her frustration level effected her other shots, and I ended up winning 21-14 after being down 11-2, so you guys do the math. The moral of the story is no matter how good you are, you cannot lose your focus at the higher levels of sporting competition.
