I just saw this girl was injured from September last year. This year she won just 2 games in her one and only match. All that means this win is nothing that big, it's big because Vekic is just 16, big promise and it is GS. But we really don't know how good Vekic really is.
However, we can't expect big results until her 20th birthday.
she had a decent win against pliskova in sydney and lost in a tight three setter there...
