Rafael Nadal follows through on a forehand during his win over Ivan Dodig in the third round of the men’s draw.

NEW YORK — Rafael Nadal crushed another opponent at the US Open, beating Ivan Dodig, 6-4, 6-3, 6-3, in the third round Saturday.

The second-seeded Spaniard has lost just 21 games through three matches. He has faced only five break points, saving each one of them.

The 38th-ranked Dodig beat Nadal at the hard-court tournament in Montreal two years ago. But Nadal is looking like the king of hard courts these days, with an 18-match winning streak on the surface.

He closed out the victory with a service winner to win the last game at love.

“I think I played a correct match today,” said Nadal. “To be able to win against him in straight sets is great news. I played better today than in the previous matches. Always a positive thing.

‘‘I am winning because I am playing well from the baseline and I am making the right decisions in the right moments. Every win means a lot. I’m happy with the way that I am playing, and trying to be ready for the next [match].’’

The No. 2 seed in the men’s draw has now reached the round of 16 at the US Open in each of his past seven trips to Flushing Meadows.

Federer rolls to win

Roger Federer moved into the fourth round of the US Open for the 13th year in a row. The 17-time Grand Slam champion raced through a 6-3, 6-0, 6-2 victory over 63d-ranked Adriano Mannarino in only 1 hour, 21 minutes.

Federer compiled a 34-8 edge in winners. Through three matches, he has spent 4½ hours on court, dropping a total of only 21 games. Federer, who won five consecutive US Opens from 2004-08, next plays 19th-seeded Tommy Robredo .

Isner bows out

Despite 26 aces and plenty of home-crowd support, unlike in his previous match, 13th-seeded John Isner lost to 22d-seeded Philipp Kohlschreiber in the third round for the second consecutive year.

Kohlschreiber’s 6-4, 3-6, 7-5, 7-6 (7-5) victory over the highest-ranked American means the host country has only one man left: 109th-ranked Tim Smyczek, whose third-round match is Sunday against 43d-ranked Marcel Granollers.

After beating France’s Gael Monfils in the second round, Isner said he was ‘‘disappointed’’ that fans were cheering so vociferously for Monfils. On Saturday, there were chants of ‘‘U-S-A! U-S-A!’’ in the second set, and ‘‘Here we go, John! Here we go!’’ in the fourth set — but Isner failed once again to figure out Kohlschreiber at Flushing Meadows.

Ferrer prevails

Earlier in the day, fourth-seeded David Ferrer needed nearly three hours to down 172d-ranked qualifier Mikhail Kukushkin, 6-4, 6-3, 4-6, 6-4. No. 10-seeded Milos Raonic beat 23d-seeded Feliciano Lopez, 6-7 (4-7), 6-4, 6-4, 6-4.

Janko Tipsarevic, seeded 18th, also needed four sets to knock off 20-year-old American Jack Sock, 3-6, 7-6 (7-1), 6-1, 6-2. Tipsarevic and Ferrer will square off in the fourth round.

Also, eighth-seeded Richard Gasquet and No. 10 Milos Raonic set up another fourth-round matchup with victories.

Williams sisters win

After a late night playing singles, Serena Williams returned Saturday afternoon and teamed with sister VenusWilliams for a 6-4, 6-4 doubles win over Americans Raquel Kops-Jones and Abigail Spears. Serena Williams didn’t wrap up her singles win over Yaroslava Shvedova the night before until 1:05 a.m.

The Williams sisters are in search of their 14th Grand Slam tournament doubles championship.
