A focused Nick Kyrgios conceded just seven games in powering Australia to a 2-0 lead over the Czech Republic in the first day of their Davis Cup World Group tie on Friday.
The controversial world number 15 took just 95 minutes to reel off a 6-2, 6-3, 6-2 win over the 157th-ranked Jan Satral and tighten Australia’s grip on the hardcourt tie at Kooyong in Melbourne.
Rookie Jordan Thompson upset Czech number one Jiri Vesely 6-3, 6-3, 6-4 in the opening singles match in two hours and six minutes.
Thompson, 22 and ranked 65, made surprisingly light work of the 54th-ranked Vesely to sink the Czech Republic’s hopes of splitting the opening day singles.
Kyrgios, who was fined US$5,500 for swearing and throwing his racquet after a stormy second round exit to Andreas Seppi at last month’s Australian Open, showed no such behaviour under the watchful eye of Australia captain Lleyton Hewitt.—AFP
