Rusty former World No.2 Alexander Zverev crashed to defeat Saturday in his first ATP match since tearing ankle ligaments at the French Open in June.

The two-time ATP Finals champion hit eight double faults in losing 6-4, 6-2 to 81st-ranked Jiri Lehecka at Sydney’s Ken Rosewall Arena to give the Czech Republic a 1-0 lead in their tie against Germany.
