Wildcard Serena Williams is the ultimate Wimbledon question mark
Serena Williams, an indomitable force for the best part of two decades, launches her latest bid for a record-equalling 24th Grand Slam at Wimbledon next week as the tournament's biggest question mark after ending a year-long absence from competition. Williams played doubles at the Eastbourne International with Tunisian Ons Jabeur this week but the former world number one has not featured in a competitive singles match since limping out of last year's first round at the grasscourt major through injury.
