WASHINGTON (AP) _ Top-seeded Yevgeny Kafelnikov and unseeded Martin Damm took care of the Black brothers in the opening round of the Legg Mason Classic on Tuesday.

Kafelnikov, ranked No. 2 in the world, overcame a horrid start for an 0-6, 6-2, 6-4 victory over Wayne Black, while Damm eliminated 12th-seeded Byron Black 6-2, 6-2.

Kafelnikov attributed his slow start to the weather.

``It's entirely humid and hot here, but I was happy to get through it,'' the Russian said after eliminating the younger of the brothers from Zimbabwe. ``Hopefully, I'll be playing my best tennis in my next match on Thursday.''

Damm, of the Czech Republic, was ranked No. 42 on the ATP Tour in 1997, but is now 105th. He entered the match against Black having lost three straight opening-round matches and four matches in a row overall. He was also 1-5 against Black.

But he seemed to handle Black, who won an ATP event in India in April, with relative ease.

``The result looked easy, but it wasn't easy at all,'' Damm said. ``I was losing a lot of matches in the last few weeks, and it was taking away a lot of confidence.''

In other matches involving seeded players Tuesday, No. 4 Todd Martin overcame Kristian Pless of Denmark, 6-4, 6-4; No. 6 Nicolas Kiefer of Germany eliminated Mashiska Washington 6-4, 6-2; No. 8 Marat Safin of Russia topped Sebastian Lareau of Canada, 7-5, 7-6 (7-2); and No. 14 Jan Kroslak of the Czech Republic beat Ben Ellwood of Austria, 6-2, 6-4.

Kiefer also struggled with the weather.

``This is one of the five hottest places I've ever played in,'' said Kiefer, winner of two ATP events this year. ``You just have to keep your concentration and focus.''
