It was a tough year for me, '89, losing two Slam finals and losing another five finals. It wasn't until I won the Masters, or what's now called the ATP Finals, that things changed again. Suddenly I won seven tournaments in 1990 and became No. 1.
I am tired of all this sort of thing called science here... We have spent millions in that sort of thing for the last few years, and it is time it should be stopped.
