Brazilian qualifier Thomaz Bellucci has caused an upset in the second round of the Italian Open by beating 14th seed Roberto Bautista Agut in three sets.

Bautista Agut dominated in the opening set, overwhelming the South American on his way to clinching it 6-1.

However, world number 68 Bellucci fought back emphatically in the second, breaking the Spaniard twice before levelling the contest 1-6 6-1.

Bellucci landed a blow midway through the decider to go 4-2 ahead, and from there he was able to hold his nerve and secure a 1-6 6-1 6-4 victory.

Waiting for the 27-year-old in the next round will be top seed and defending champion Novak Djokovic.
