Miami, United States, 23 March 2013 | tennis.com.au

Gilles Simon has ended Lleyton Hewitt’s run at the Sony Open in Miami with a straight-set victory in the second round on Friday.

The 11th-seeded Frenchman defeated Hewitt 6-3 6-3 in one hour and 16 minutes on Grandstand court at Crandon Park, progressing to a third round battle against Slovene Grega Zemlja.

Zemlja upset No.23 seed Florian Mayer of Germany in straight sets.

Despite making just 47 per cent of his first serves, Simon was extremely successful when he landed them, winning 80 per cent of points and facing just three break points throughout the match.

He was even more devastating on the return, bringing up 11 break point opportunities and converting five against Hewitt, a wildcard into the main draw in Miami.

It was Hewitt’s first appearance in Key Biscayne since 2009.

One Australian remains standing in the tournament – Bernard Tomic will take to stadium court on Saturday afternoon (Miami time) for his blockbuster battle against No.2 seed Andy Murray.
