Rome - Stanislas Wawrinka saved energy with an efficient effort to post a win into the second round of the Rome Masters 6-3, 6-4 over Russian Igor Kunitsyn on Monday.
The Swiss, who lost the title match a year ago to Novak Djokovic but earned a Top 10 place for his efforts on the clay of the Foro Italico, said he did what he needed to win.
"It was enough today to win, I'm very happy to play around an hour for two sets."
