Serena Williams eased into the fourth round of the US Open with a straight sets victory over Ekaterina Makarova.
The American, who has won this event three times, exacted revenge for her
Australian Open thrashing by Makarova
earlier in the year with a 6-4 6-0 win.
Fourth seed Williams broke the Russian to win the first set and raced through the second to win in 80 minutes.
, seeded second, came through a tough match with Jelena Jankovic, winning 6-3 7-5.
"I was feeling like I was melting there," said Radwanska, who will play Italy's

Jankovic had 37 unforced errors in the match to Radwanska's 15 and the victor conceded her patience had paid off, adding: "I survived the match. In the second set, I was just better for a couple of points.
"With the hot conditions, you really have to fight more yourself than against the opponent."
Williams, 30, opened strongly against Makarova but the Russian battled hard, holding serve the first four times, but after losing the first set she wilted.
"She beat me in Australia, so I knew I needed to play better going into today and I definitely felt I played better," added Williams, who won the US Open in 1999, 2002 and 2008.
"Mentally I am just going with the flow, this is my home crowd and it's hard not to be excited to play here, being an American and playing in New York."
