2017 High: A year removed from capturing the Wimbledon boys’ title, Denis Shapovalov has had a fairly rapid ascent up the rankings, peaking at No. 130 in July. His biggest moments have come on the ATP Challenger circuit in front of his home crowd in Canada, including winning his first career title at that level in Drummondville earlier in the year, and a second in Gatineau last month.
