LONDON, June 11 (UPI) -- Andy Roddick took a pair of tiebreakers Thursday from Lleyton Hewitt and moved into the quarterfinals of the $1 million Aegon Championships in London.
Roddick and Hewitt have won eight of the last nine Aegon titles -- Rafael Nadal won last year -- and played very even Thursday. Neither player managed a service break but Roddick was able to win the tiebreakers in the 7-6 (7-2), 7-6 (7-4) victory.
Roddick is paired against ninth-seeded Ivo Karlovic in Friday's quarterfinals. Karlovic used 19 aces in taking out Nicolas Mahut 6-3, 6-4.
Top-seeded Andy Murray didn't face a break point in his 6-4, 6-4 win over Guillermo Garcia-Lopez while No. 8-seeded Mardy Fish ousted 10th-seeded Feliciano Lopez 6-1, 6-4. Murray and Fish are quarterfinal opponents.
Third-seeded Gilles Simon was upset 6-1, 2-6, 6-2 by No. 14-seeded Mikhail Youzhny, who next meets James Blake. The sixth-seeded Blake defeated Sam Querrey 6-4, 4-6, 6-3 on Thursday.
The fourth quarterfinal has Steve Darcis playing Juan Carlos Ferrero. Darcis advanced on a walkover when fourth-seeded Gael Monfils withdrew with a wrist injury while Ferrero took out Xavier Malisse 6-4, 7-5 (7-4).
