Gilles Simon ousts Jo-Wilfried Tsonga in Monte Carlo

Gilles Simon has booked his place in the semi-finals of the Monte Carlo Masters with a straight-sets win over fellow Frenchman Jo-Wilfried Tsonga.

Simon got off to an explosive start as two breaks of the Tsonga serve saw him race into a 3-0 lead.

However, Tsonga broke back instantly before he squared proceedings at 5-5.

Despite the world number five's resurgence, Simon clinched a final break before he served out the set 7-5.

Tsonga looked to have wrestled the initiative in the second with an early break, but the world number 15 hit back twice late in the set to win 6-4 and progress to the last four.
