SAO PAULO (AP) — Top-seeded Tommy Haas came back to defeat Horacio Zeballos of Argentina 6-3, 5-7, 6-2 to advance to the Brazil Open semifinals on Friday.
Haas broke Zeballos' serve twice in a row in the decisive set to close the match and take a step closer to his second final of the year. The 12th-ranked German lost to Marin Cilic in the final in Croatia earlier this month.
Haas will next play Paolo Lorenzi of Italy, who reached his first ATP semifinal with an upset 7-6 (6), 6-7 (4), 6-4 win over fourth-seeded Juan Monaco of Argentina.
"Lorenzi has been around for a long time so this is a goal I'm sure he has been waiting to achieve for a lifetime," Haas said. "He has nothing to lose and is going to try to go one more and get to his first ATP tour final. He is a dangerous player. I'm going to have to try to play some of my best tennis."
The 114th-ranked Lorenzi broke Monaco's serve to go up 4-3 in the final set and held on to close the match in 2 hours, 34 minutes at the Ibirapuera Arena.
The 32-year-old Italian squandered a match point before losing the second set, but was in control in the third to pick up the win in the ATP 250 tournament in South America's biggest city.
Lorenzi served 12 aces en route to his first pro semifinal after five career quarterfinal losses.
