Day 4, Part 1

Sue Barker presents live coverage as day three of the 2018 Wimbledon Championship gets under way at the All England Club, including Boulter v Osaka, Zeballos v Djokovic, Halep v Zheng, Del Potro v Lopez, Edmund v Klahn and Muguruza v Van Uytvanck. The second-round stage concludes on Thursday and the big names in the bottom half of the draw are looking to avoid an embarrassing early exit. Last year, Roger Federer beat Serbia's Dusan Lajovic and took another step towards what turned out to be an historic eighth men's singles title.
