The 22nd seed, nicknamed "Baby Fed" because his game resembles Roger Federer's, ousted unseeded Spaniard Roberto Bautista Agut 6-3, 3-6, 6-2, 6-4 in two hours 24 minutes on Margaret Court Arena.

The 22-year-old, who is dating Maria Sharapova, will face 13-time Grand Slam champion Nadal in the last eight on Wednesday. "We all know that he has won tons of slams. He's been a tremendous competitor. He's Rafa. We all know him," Dimitrov said. (Related: Sharapova knocked out | Who is Sharapova?)

"But I just want to put myself in position to play those guys. I have had tough battles with him in the past. Played a couple times on clay. There were always little things missing.

"I'm quite happy with the way I'm performing so far. So I like my chances." (Nadal beats Nishikori in pre-quarters | Murray tested)

Dimitrov broke the Spaniard's serve four times and won 85 percent of his first-serve points in a strong performance with 38 winners. While five Bulgarian women have played in quarter-finals at a Grand Slam, Dimitrov is the first man from his country to reach the last eight at a major tournament.
