#4. He had a very controversial moment at the Davis Cup this year
Shapovalov was chosen to represent Canada in their World Group 1st round tie against Great Britain at Ottawa in February. He lost his singles match against Dan Evans in straight sets but wins by Vasek Pospisil in both his singles matches and a Great Britain victory in the doubles match made the score 2-2, which meant that the match between Shapovalov and Kyle Edmund would be the decider.
Edmund completely outplayed the teenager, winning the first and second set 6-3 and 6-4 respectively. In the third game of the third set, Shapovalov dropped his serve following which, he hit a ball aimlessly towards the spectators in anger.
However, the ball travelled straight to the chair umpire and hit him in the eye. The Canadian was disqualified and Edmund won by default, thus sending Great Britain to the quarter-finals where they would be thrashed 4-1 by France.
Shapovalov was eventually fined $7,000 for his actions.
