Fourth seed David Ferrer continued his straightforward progress through the draw with a 6-2 6-3 7-6 (14/12) victory over Dutch qualifier Igor Sijsling in the second round of the US Open.
The Spaniard has been elevated into the top four in the absence of his injured countryman Rafael Nadal but is going about his business very much under the radar.
Ferrer is having the best season of his career, reaching the semi-finals at the French Open and the quarter-finals of Wimbledon, and his only tight moments today came in a lengthy third-set tie-break.
There was a popular victory, meanwhile, for American college champion Steve Johnson, who served his way to a 6-7 (3/7) 7-6 (7/5) 6-3 6-4 win over mercurial Latvian Ernests Gulbis.
Johnson, a 22-year-old wild card, becomes the first college champion to reach the third round of the US Open since Sargis Sargsian in 1995.
