HOUSTON (AP) -- Fifth-seeded Tommy Haas dominated Andy Roddick on clay again, beating the No. 1 seed a fourth straight time in a quarterfinal match Friday night at the U.S. Men's Clay Court Championship. Haas rallied from one set down to win 6-7 (1), 6-4, 6-4 in a matchup that Roddick said could have been the final. It was two years ago. Roddick had two chances to break Haas in the final game, but he was unable to return Haas' serve and got aced on the second opportunity. Haas closed out the match two points later. He hit a forehand winner that cleaned the line and a forehand by Roddick hit the tape but the ball bounced back on his side. Haas will play American Mardy Fish in one semifinal Saturday. Seventh-seeded Paul Goldstein of the United States plays Austria's Jurgen Melzer in the other semifinal. Haas, from Germany, beat Roddick twice on clay in 2002 in Monte Carlo and Rome, and again in 2004 in the finals here. Roddick led 4-3 in the second set and had two chances on Haas' serve in the eighth game -- the longest of the match -- to set up himself to serve for the match. But Haas stiffened to win the game and then won eight straight points to close out the set, 6-4. Haas needed just five points to break Roddick in his second service game of the third set to go up 2-1. But Roddick broke right back to level it. In the seventh game Haas needed just one break chance to go up 4-3 and he did it in flashy fashion. Haas barely returned the serve to his backhand and Roddick volleyed the ball wide to the other side. The German sprinted the width of the court and hit a down the line winner on the run to go up 4-3. Fish beat fellow American Vince Spadea, 4-6, 7-6 (1), 6-4 in a match that saw its share of service breaks. Fish got the first one in the deciding set when he hit an backhand winner down the line on his fourth chance to break Spadea in the fifth game to lead 3-2. Spadea, who won only five more points in the match, reached the quarterfinal when fourth seed Marcos Baghdatis of Cyprus retired at 6-2, 3-1 Thursday night because of low back pain. Fish, who did not have a match Thursday, said it looked to him that Spadea got tired as the match wore on. "He got a break but he still had to work hard in the first set (Thursday night), and I was fresh." Fish, who jumped out to a 6-0 lead in the tiebreaker before going for a big forehand return of serve that went long, said he felt he had the momentum going into the breaker. "I had chances before and just had some stupid points at key times," he said. "I still felt I had a chance to win. I just had to play more aggressive on the big points." Goldstein struggled occasionally with his serve but he was steady enough to beat Albert Montanes of Spain 6-3, 6-4 in an early quarterfinals match. Goldstein was broken in the third game of the first set but he broke back in the fourth game and survived a challenge by Montanes to hold serve in a lengthy fifth game. Goldstein wrapped up the match at the first match point when he ran down a drop shot by Montanes and returned it as the Spaniard made a slap at the ball. Melzer gained the spot with a 7-5, 6-4 win over Fernando Vicente of Spain. The two traded breaks twice in the closing set to put Melzer up 5-4. He got to match point on a drop shot winner and closed out the match two points later on an overhead smash.
