Read how all the action unfolded below:
11.21amGood morning! The first match of the day of the Philippe Chatrier court has just finished, so Roger Federer and Lukas Lacko will be heading out the show court in just a few minutes time. On paper, this should be a fairly easy opening match for the former Roland Garros champion, but Lacko can be a tricky opponent, so it should be a fascinating encounter.
11.24amIt's been five years since the Swiss won the men's singles title in Paris. Since then, he's been in the final once, had a last four appearance, and been knocked out in the quarter-finals twice, included last year when he was beaten by Jo-Wilfried Tsonga.
11.27amLacko has not enjoyed such success at the French Open during his career. He's played just four matches at this event before, winning only one on his debut in 2010. Since then, he's been knocked out in the qualifiers before suffering back-to-back first-round exits.
11.29amThe players have just made their way out onto the court. The ever-popular Federer draws a big cheer from the Parisian crowd. They'll be given a few minutes to warm up and get used to the conditions on court before getting the match underway.
11.31amThis will be just the second time that these two players have faced each other. In their only previous meeting, Federer clinched a comfortable 6-1 6-1 6-3 win at the Australian Open in 2011.
11.35amLacko really isn't a fan of clay, this is actually his first tournament on the surface since he played at Roland Garros last year, so he may take a few games to find his pace this morning. While Federer is primarily known was his dominant grass game, he's looked impressive on clay this year, reaching the final in Monte Carlo before withdrawing from the Madrid Open ahead of the birth of his twin boys earlier this month.
11.38pmThe good news for today is that the weather looks fine. It's a little chilly in the French capital but bright and there's no rain forecast. The warm-ups are complete so it's time to get underway, with Lacko serving first
Lacko 1-0* FedererA couple of weak serves from Lacko allows Federer to claim a 30-0 lead, but the Slovakian manages to find his rhythm quickly to recover and wrap up the opening game of the match. That should settle any lingering nerves he has.

Lacko *2-2 FedererAfter both players claimed a point, Federer serves smoothly to ease to another hold, while Lacko looked jsut a little stiff moving around the court. He's shown a decent range of shots so far, but is yet to settle on the clay.
Lacko 2-3* FedererBREAK! Federer makes some superb returns to claim the opening two points of the game, but slips while reaching for a backhand to let Lacko back in the game.

Lacko *2-4 FedererFederer starts brightly with an ace before coming into the net to win the next two points with volleys.

Lacko 2-5* FedererBREAK! Federer is continuing to focus on coming in from the baseline, and it's paying off as he brings up two more break points. Lacko tries to do the same to keep himself in the game, but slices his volley short to give the Swiss another break. Lacko hasn't really tested the fourth seed's serve yet, but he'll need to do so in the next game to keep himself in this set.

Federer has had a break point in Lacko's last three service games, but each time the Slovakian has fought back.
