OEIRAS, Portugal: Juan Martin del Potro beat Pablo Cuevas 6-2, 7-6 (6) to reach his second final of the season at the Estoril Open Saturday, where Fernando Verdasco awaits after the Spanish player got past Milos Raonic. Del Potro, the 2009 US Open champion, dropped only six points on his first serve and hit four aces, while Cuevas was unable to claim a single break chance against the fifth-seeded player. Del Potro broke Cuevas' serve twice in the first set but failed on eight break chances in the second as his 65th-ranked opponent took it to a tiebreaker where the Argentine saved a set point before converting his first match point to dispatch his Uruguayan opponent. Verdasco's lone break of the hard-hitting Raonic's serve was enough to secure the first set 6-4 before the Canadian player retired just after the start of the second set. The 12th-ranked Verdasco had previously lost to Raonic in the final at San Jose and in Memphis. Both players were on court for the second time Saturday after rain then darkness had delayed their quarterfinals matches on Friday. Verdasco rallied to beat Kevin Anderson of South Africa 6-7 (2), 6-2, 6-3 and Raonic battled another rain delay to secure a hard-fought 7-6 (4), 4-6, 6-3 win over Frenchman Gilles Simon. Meanwhile, Anabel Medina Garrigues of Spain braved a rain delay to capture her 10th WTA title by beating Kristina Barrois of Germany 6-1, 6-2 in the women's final.

In the final, Davydenko will play fifth-seeded Florian Mayer, who beat fellow German Philipp Petzschner 6-3, 6-4.
