LONDON, July 11 : Alexander Zverev will hope the old adage about London buses - you wait an age for one and then two come along at once - holds true for his tennis career on Sunday as he attempts to upset the odds and dethrone Jannik Sinner in the Wimbledon final.It will be a daunting challenge for the newly-crowned French Open champion though as his reward for reaching his first Wimbledon final is a clash with the Italian who has beaten him nine times in a row including winning the last 14 sets.On the positive side though for Zverev - the first German to reach the men's final at Wimbledon since Boris Becker in 1995 - is that he suddenly seems to be walking taller, which is saying something for a man standing at 6 feet 6 inches.Zverev seized his chance at Roland Garros after a wrist injury
