The youngest tennis player in the Top 10, Alexander Zverev, ranked #4, caused a major upset on Sunday, beating World #1, Novak Djokovic in straight sets to claim the biggest title of his career, the ATP World Tour Finals at London’s O2.

Known as ‘Sascha’ (a common Russian nickname for Alexander) the twenty-one year old German of Russian descent, also beat Roger Federer in Saturday’s semis. Novak comfortably won their group stage match, but wins over John Isner and Marin Cilic secured Sascha’s advancement to the last four. He previously beat Novak in the 2017 Italian Open to claim his first Masters 1000 title and enter the top 10 for the first time. Coached by his father, Alexander Snr since the age of five, the team was joined in August this year by Ivan Lendl, who was influential in Sunday’s victory.

Sascha did sign a sketch for me this year at the O2, but this one was graphed and dedicated at last year’s year-ending tournament.
