Stan Wawrinka and David Ferrer eased into the second round of the US Open on Tuesday after routine wins.
The Swiss star was made to work hard in the opening set against Fernando Verdasco but would emerge victorious 7-6(4), 6-4, 6-4 in New York.
The third seed would save two break points in the lead up to the first set tiebreaker. After going up 3-1, Wawrinka never looked back.
The two-time grand slam winner was unbeatable on serve, facing just one break point in the following two sets as two breaks took him to a comfortable win.
The 31-year-old was a semi-finalist last time around at Flushing Meadows, losing out to Roger Federer.
