Bet In-Play: Wimbledon Men's Singles Semis

The makeup of today's Wimbledon men's singles semi-finals is not quite as most would have expected pre-tournament, but it will be a great day of tennis action nonetheless. Roger Federer, Rafael Nadal and even Jo-Wilfried Tsonga all exited the grand slam early, but two of the world's top four players will be in action.

World number one Novak Djokovic holds an 8-3 lead over his semi-final opponent, eighth-seeded Argentinian Juan Martin Del Potro. But here's the catch - Djoka has never played his rival on grasscourt before. The two are tied 2-2 head-to-head on clay, while Djoka holds a commanding 6-1 lead on hardcourts.

In the other semi-final, second-seed and hometown favorite Andy Murray faces a rather unpredictable matchup against Jerzy Janowicz, the 24 th seed. Janowicz will make history when he steps on to the All England Club's Center Court today, as he becomes the first Polish man to play in a grand-slam semi-final.

William Hill Sports has updated its odds on tournament winner following the quarter-final results, and they are as follows: Djokovic, 4/6, Murray, 7/4, Del Potro, 14/1, and Janowicz clearly the outsider at 16/1.

Hill is taking the full range of wagers on both men's singles semi-finals. Punters can place a pre-match bet on at least eight different match markets (including match result), 23 separate set markets, and tiebreak specials.
