It’s home field advantage for Albert Ramos…

The 26-year-old Spanish professional tennis player upset Russia’s Nikolay Davydenko 6-4, 6-4 in the first round of the Barcelona Open to set up a meeting against top-ranked Rafael Nadal.

Ramos will play the defending champion and eight-time winner during Wednesday’s second-round match.

Nadal was knocked out of the quarterfinals of the preceding Monte Carlo Masters — his earliest exit from the clay-court tournament since 2003.

In second-round play on Tuesday, fourth-seeded Kei Nishikori of Japan was a 6-1, 4-6, 6-3 winner over Spain’s Roberto Bautista.

No. 16 Benoit Paire of France was the only seeded player to exit, retiring at 6-4, 5-1 down to Andrey Golubev of Kazakhstan.
