World No.2 Roger Federer takes on Croatian No. 22 seed Ivo Karlovic in the Wimbledon men’s quarterfinals later this afternoon.

The 6ft 10in Karlovic makes his first Wimbledon quarter-final debut after he defeated seventh-seeded Spaniard Fernando Verdasco on Monday. He has blasted down 137 aces in four matches so far and has yet to lose his serve at the tournament. Ivo has a poor record against Federer, though, having won just once in nine attempts.

The Swiss tennis ace is bidding for his sixth Wimbledon championship and a record 15th major title overall.

The match starts at 13:00 London (08: 00 ET).

UPDATE: Roger Federer reached his 21st consecutive Grand Slam semi-final after beating Ivo Karlovic in straight sets, 6-3, 7-5, 7-6 (7-3).
