Kyle Edmund was victorious in the first round of the Nastase Tiriac Trophy, defeating 2013 champion Lukas Rosol in straight sets.

After edging a first-set tie-break the South Africa-born 21-year-old fell 4-1 behind in the second, but he staved off three set points as he charged back to force another breaker.

Edmund – who fired down 11 aces – secured an early break to enable him to complete a  7-6 (7-4) 7-6 (7-5) victory on his sixth match point, and set up a meeting with fourth seed and defending champion Guillermo Garcia-Lopez in the second round.

Guido Pella fought back from 4-2 down to edge Romanian Adrian Ungur out for the opening set, and the world number 193 offered little resistance as the Argentine completed a 7-5 6-2 win.

Another home hope, wildcard Marius Copil, forced a third set but ended up losing out to Damir Dzumhur 6-1 3-6 6-2.

Taro Daniel took just 24 minutes to win the second set as he made light work of defeating Austrian qualifier Michael Linzer 6-2 6-0.
