MONTREAL -- Riding high earlier this year after upset wins over some big-name WTA Tour stars, Canadian teenager Leylah Annie Fernandez appeared primed to take her game to the next level.

Singles matches at the Credit One Bank Invitational began late Tuesday afternoon with play continuing through Sunday.

The Montreal native, based in Boynton Beach, Fla., made it through Australian Open qualifying last January before falling in the first round of her women's singles Grand Slam debut.

Her father and primary coach, Jorge Fernandez, said he cut training down to less than half of what they were doing before the pandemic, noting it has been tough to plan due to the uncertainty about the rest of the season.

In the leadup to Charleston, Fernandez played some training games against players like Monica Puig, Sophie Rogers and others, but the intensity was dialled back.

The Invitational is part of the Tennis Channel's Re(Open) Tour, a series of events and exhibitions taking place during the pandemic.
