• September 10, 1989 – Boris Becker becomes the first German man to win the U.S. Open, defeating Ivan Lendl in the final. Lendl appears in his eighth straight U.S. Open final, which ties him with Bill Tilden for the all-time record.^[1]

• Agassi-Connors^[2]

Played on Stadium Court, National Tennis Center, Flushing Meadows, New York. Originally shown by USA Network with play by play commentators: Ted Robinson and Vitas Gerulaitis

• 19yr old Andre Agassi with long flowing hair and jean shorts wearing a Nike shirt playing with a Donnay racquet, being Coached by Nick Bollettieri.
• 37yr old Jimmy Connors with a white bandana around his neck wearing a Slazenger "Triangle" shirt playing with a Slazenger racquet.

After a solid opening set, Agassi loses the next two, with Connors winning the third 6–0. Agassi then has to save three break points to win the fourth set to tie the match. The fifth starts in Agassi's favor, breaking twice and jumping to a 5–1 lead, but Connors rallies back with a break to 5–4. Finally, with double match point, Agassi misses a backhand down the line, but then pulls off a backhand dropshot which Connors hits long.

• Down match point in his 2nd round match, Boris Becker benefits from a net-cord passing shot just out of the reach of Derrick Rostagno in his come-from-behind victory. Also on the stadium, qualifier Paul Haarhuis stuns number four seed John McEnroe in one of the biggest upsets in U.S. Open history. In the next match on the stadium court, 18-year old Pete Sampras upsets defending champion and number five seed Mats Wilander.^[1]
