1. In 2000, the top-ranked Agassi defeated No. 3 Sampras in the semi-finals of the Australian Open in five sets, which was an important win for Agassi who had lost 4 of the previous 5 matches against Sampras.

3. Among his upsets of players ranked in the world's top 3 were his defeat of No. 2 Boris Becker, 3–6, 6–3, 6–4, in Cincinnati in 1989, No. 2 Edberg, 7–6, 6–7, 6–4, in Los Angeles in 1991, No. 3 Sampras, 6–3, 6–4, in London in 1992, and No. 3 Jim Courier, 6–4, 6–4, at Memphis in 1994, Edberg, 6–4, 2–6, 7–6, in Cincinnati in 1989, and perhaps most significantly, No. 2 John McEnroe, 5–7, 6–4, 6–1, at the Masters Grand Prix in 1985, which sent McEnroe into his first six-month break from tennis.
