Lorenzi's dream run continues

Paolo Lorenzi reached his first ATP Tour final after top seed Tommy Haas retired with a shoulder injury during their semi-final in Sao Paulo.

The 32-year-old Lorenzi, ranked 114th in the world, was leading the German world No 12 6-3 3-2 at the time.

Haas said he "felt a lot of pain" in his right shoulder when he slammed his racket to the ground in frustration after losing his serve at 3-3 in the first set.

He kept playing despite needing medical treatment several times, and finally gave up after going down another break in the second set.

The German said the pain was "getting worse during the match" and it did not allow him to "compete the way" he wanted.

"After I threw my racket when I got broken at three-all I felt a lot of pain in my shoulder and it never really got away," the 35-year-old Haas said. "The pain was getting worse. And the smart player's decision has to be not to continue, unfortunately.

"I've had three shoulder injuries and one elbow injury, so my shoulder is not the youngest, not the way it needs to be.

"I'm very happy that I can still play at a high level, but sometimes the shoulder is very, very tired, very, very stiff, and it tells me not to continue. But I'll try to play as long as I can, hopefully for the rest of the season, then we will see."

Lorenzi will play in his first ATP final against world No 61 Federico Delbonis of Argentina, who beat home favorite Thomaz Bellucci of Brazil 6-4 6-7 (5) 6-4 in the other semi-final.

Lorenzi had never previously advanced past the quarter-finals of any Tour event.

"When I started this tournament I never thought that I would be playing in the final," Lorenzi said. "Now tomorrow let's see what happens. Right now I'm just happy to be in this final."
