Serena Williams remains on course for her fourth US Open title as she eased into the fourth round with a straight sets victory over Ekaterina Makarova. The American (8/11 to win the US Open) 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.
Williams opened strongly against Makarova but the Russian battled hard, holding serve the first four times, but after losing the first set she wilted. Williams will play Andrea Hlavackova (12/1 to win the match) in round four after Hlavackova beat Maria Kirilenko in three sets 5-7 6-4 6-4.
Second seed Agnieszka Radwanska (28/1 to win the US Open) came through a tough match against the 2008 finalist Jelena Jankovic, winning 6-3 7-5. Jankovic had 37 unforced errors in the match to Radwanska's 15 but the beaten 2012 Wimbledon finalist commented on the humidity saying "I was feeling like I was melting there. 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."
Radwanska will play Italy's Roberta Vinci (13/8 to win the match) in round four after the 20th seed knocked out 13th ranked Dominika Cibulkova 6-2 7-5.
