NEW YORK (AP) _ Paul Haarhuis, the man who beat Boris Becker, isn't heading home to the Netherlands anytime soon. He won his fourth-round match against Carl-Uwe Steeb 6-2, 6-3, 6-4 to reach his first-ever Grand Slam quarterfinal.

The No. 45-ranked Haarhuis' previous Grand Slam best was the fourth round of the 1989 U.S. Open - the year he beat John McEnroe in the second round.

Is Haarhuis making headlines back home because of his Becker victory?

''I don't know, I wasn't there,'' Haarhuis said. ''I talked to my dad only briefly. He called here and watched on TV. He was very happy for me...I don't know if it was big news.''

How do you celebrate pulling off a big upset over the No. 1-ranked player in the world?

''Some friends said 'Let us meet together for dinner','' Haarhuis said. ''So we kind of had dinner with eight or nine people. But nothing more than that...because it is not the end of the week. There is a next match coming.''

Haarhuis admitted it was difficult to focus on his next match after his victory over Becker. He was happy, however, with the way he played against Steeb.

Haarhuis is the first Dutchman to get to a U.S. Open quarterfinal round since Tom Okker. Okker was the runner-up at this event in 1968 and a semifinalist in 1971.

Haarhuis' next opponent is Jimmy Connors, the hero of Flushing Meadow. Connors' won a four-hour, 42-minute fourth-round match over Aaron Krickstein on Monday.

If you're looking for Gabriela Sabatini on noon this coming Wednesday, don't head for the U.S. Open.

Sabatini, the reigning U.S. Open champion, will be in midtown Manhattan to kick off ticket sales for the $3 million Virginia Slims Cahampionhips. The Argentine tennis star will present a free pair of tickets and special commemorative T-shirts to at least the first 20 people on line at the Madison Square Garden box office, the site of the Championships.

The Championships feature the top 16 women's players in the world and will take place at the Garden, Nov. 18-24, 1991.

Jimmy Connors' newest advertising endorsement for Nuprin seemed appropriate after he survived against Aaron Krickstein.

The birthday boy turned 39 years old Monday and probably has some aches and pains. So, a little Nuprin, an ibuprofen medication, seems a clever ad campaign for Connors.

The new Connors commercial opens with the famed tennis player stating, ''I hurt, but I'll be back.''

And he will be back against Haarhuis in the quarterfinals later this week.

Fellow pro Michael Chang is also a Nuprin spokesperson. Nuprin, a Bristol Meyers product, is also the ''official pain reliever'' of the Women's Tennis Association and the U.S. Olympic team.
