Shapovalov, from Richmond Hill, Ont., entered the ATP Masters 1000 event with a record of 2-7 in main draws this year.

The 31st-seeded Fernandez, who had a first-round bye, had no aces and four double faults while winning 70 per cent of her first serves. But she was especially effective in breaking her opponent, converting on all six chances she got in the match.
