Top seed Haas falls to unheralded Johnson at Delray Beach

A day after displaying dominant form top seed Tommy Haas suffered an upset loss to unheralded American Steve Johnson 6-4 2-6 7-6 in the second round of the Delray Beach Open on Wednesday.

Haas had opened the tournament with a breezy win over Wayne Odesnik Tuesday but the 35-year-old could not repeat the feat against an aggressive young opponent who had to win two qualifying matches to make the tournament`s main draw. Johnson banged out 13 aces and did not fold when Haas mounted a rally and claimed the second set. In the decisive third, Johnson held firm and dominated the tie-breaker to gain a huge victory in his young career. "I`ve had a few wins I`ll never forget, and this is one of them," Johnson told reporters. "I played a good week in Dallas (Challenger) two weeks ago and I played two good matches in qualifiers (here)." The win marks the second time this season Johnson has defeated a top-20 opponent, after he took down Kevin Anderson, who was ranked 20th at the time, last month in Auckland. This is not the first time Haas has bowed out of the Delray as a top seed as he was also ousted in the first round in 2010. "I struggled at times with the lights and my focus, but I`m not going to take anything away from (Johnson)," Haas said. "I hate to lose, but I`m happy for him." In other action, Australia`s Lleyton Hewitt was also sent home early after he retired because of a right shoulder injury. He was trailing fellow countryman Marinko Matosevic 7-6. Fourth seed Anderson also advanced when opponent Ivo Karlovic was forced to retire early in the match, while sixth seed Feliciano Lopez overcame a one set deficit to beat Adrian Mannarino 4-6 6-4 6-2. Marin Cilic easily knocked out Benjamin Becker 6-1 6-3.
