Boris Becker won the opening three matches of his rivalry against Andre Agassi, but the American turned the tide in his favor by winning eight matches in a row and finishing with a 10-4 lead. In a 2017 interview with the Player's Tribune's Unscripted, Agassi revealed how Becker's 'weird tick' with his tongue during his serve routine helped him nullify the effects of the German's deadly serves.

"I started to realize he had this weird tick with his tongue," Agassi said. "I'm not kidding. He would go into his rocking motion, his same routine, and just as he was about to toss the ball, he would stick his tongue out. And it would either be right in the middle of his lip, or it'd be to the left corner of his lip. "If he's serving in the deuce court and he put his tongue in the middle of his lip, he was either serving up the middle or to the body. But if he put it to the side, he was going to serve out wide."

However, he explained he then had to work hard on not letting Becker realize that he was now aware of his 'weird tick'.

"The hardest part wasn't returning his serve — it was not letting him know that I knew this," Agassi said. "I had to resist the temptation of reading his serve for the majority of the match and choose the moment when I was gonna use that information on a given point to execute a shot that would allow me to break the match open."

Andre Agassi then revealed that he told Boris Becker about this after he had retired, when the two hung out at the Oktoberfest in Germany, which left Becker in complete shock.
