UMAG, Croatia (AP) -- Portugal's Joao Sousa upset third-seeded Italian Andreas Seppi 6-2, 6-2 in the second round of the Croatia Open on Wednesday.
Sousa played steadily from the baseline as Seppi made a number of unforced errors. Sousa converted six out of nine break points to win in just 69 minutes.
Seppi broke early in both sets but then lost several games in a row. He won only 29 percent of points on second serve as Sousa returned strongly.
Sousa will next play fifth-seeded Fabio Fognini of Italy, who beat Damir Dzumhur of Bosnia-Herzegovina 6-3, 7-5.
Fognini came back from being 1-4 down in the second set to win in straight sets. He was a runner-up in Umag in 2013 and a semifinalist on three more occasions.
In the remaining first round matches on Wednesday, Dusan Lajovic defeated fellow Serb Laslo Djere 6-3, 6-3, while Blaz Kavic of Slovenia beat 17-year-old wild card entrant Andrey Rublev of Russia 7-6 (0), 2-6, 6-3.
