Kei Nishikori rallied from a set down to beat Viktor Troicki 5-7, 6-2, 6-3 on Tuesday in Rome to progress to the Internazionali BNL d'Italia third round.
After a tight start to the match which saw neither player give anything way, the Japanese superstar lost serve in the 12th game to concede the opening stanza 5-7.
Nishikori then regrouped and began to move more freely on the clay and became slightly more aggressive as he bounced back to win the second set with two breaks of Troicki's serve.
The 2014 US Open finalist, with all the momentum on his side, then stormed home in emphatic fashion as he again broke Troicki twice en route to winning the third 6-3 and with it the match.
Once he put a wobbly start behind him, hallmarks of Nishikori's play on the day were his consistency and patience on the surface that punishes those who try and rush points.
