Maya Joint falls at first hurdle as Tereza Valentová scores Australian Open upset

Australian No 30 seed defeated 6-4, 6-4 in 92 minutes

Local wildcard Taylah Preston wins first grand slam match

Maya Joint has vowed to return to the Australian Open stronger, after the top-ranked local in the women’s singles draw crashed out in the first round on Tuesday with a straight sets defeat to Czech teenager Tereza Valentová.

Valentová made the most of an inconsistent display from the 30th seed, winning 6-4, 6-4 in 92 minutes.

Joint, at 19 and only one year older than her opponent, struggled with unforced errors and with her serve, leaving a near-full John Cain Arena shocked and disappointed in the first match of the day.
