Up next for Roger Federer in today's quarterfinals is Ivo Karlovic, who makes a living smacking aces and service winners.

The 6-foot-10 Croat has not been broken once in 79 service games this tournament and leads all players with 137 aces.

Still, Federer is a heavy favorite, listed at -1400 to win the match.

The quarterfinal round features players of eight nationalities, with five Grand Slam tournament winners and four former No. 1s.

In other matches Andy Murray (-1400) takes on Juan Carlos Ferrero (+675) of Spain.

On Court 1, two veterans will try to get back to the Wimbledon semifinals for the first time in four years. Andy Roddick, the runner-up to Federer in 2004-05, takes on Lleyton Hewitt, who won here in 2002.

The fourth matchup features the oldest remaining player against the youngest, with the 31-year-old Tommy Haas taking on 22-year-old Novak Djokovic.

UPDATE: Looks like Federer being the huge fave was the right thing for oddsmakers to do, he made quick (very quick) work of Karlovic, beating him in straight sets.
