Philipp Kohlschreiber booked his place in round two of the French Open thanks to a 7-6 1-6 7-5 6-2 victory over Jiri Vesely this evening.
The opening set proved to be evenly contested and consequently a tie-breaker was reached. World number 19 Kohlschreiber gained control early on with a break and pressed home that advantage to win through 7-3.
However, 19-year-old Vesely responded positively in the second set and levelled up proceedings thanks to two breaks of his German opponent's serve.
The third set proved to be a decisive one as Kohlschreiber broke at 5-5, before holding his own serve to take a 2-1 lead in sets.
That prompted Vesely to take more of a chance during the fourth set in an attempt to force a decider. Instead, he committed numerous errors and Kohlschreiber took full advantage with a couple of breaks.
He will now take on either Simone Bolelli or Lu Yen-Hsun.
