London: Less than a month shy of 36 and bidding for a record eighth Wimbledon men's title, Roger Federer will play in the semifinals against 2010 runner-up Tomas Berdych of the Czech Republic. Federer is the only member of tennis' Big 4 left; No. 1-seeded Andy Murray, No. 2 Novak Djokovic and No. 3 Rafael Nadal are all gone. And Federer has been quite impressive over the past two weeks. He hasn't lost a set, while winning 63 of 66 service games. He's made only 49 unforced errors in five matches. In the first semifinal, 2014 U.S. Open champion Marin Cilic of Croatia faces 24th-seeded Sam Querrey, the first U.S. man in a Grand Slam tournament's final four since 2009.
