A homegrown product who joined the Champagne club when he was 15, Oudin canceled out Jose Fonte's opener with his 10th goal this season in the 79th minute. Ideally set up by a brilliant pass from Tristan Dingome, Oudin connected with the ball in the box and beat Lille 'keeper Mike Maignan with a left-footed shot.
Oudin has played a key role in his team's successes this season. With seven matches left to play, Reims has lost just six league games and is challenging for a place in European competition. Second-placed Lille extended its lead over Lyon to five points in their fight for the second automatic Champions League spot, but the draw opened the door for PSG to seal a sixth title in seven years. If it beats Strasbourg later at the Parc des Princes, PSG will have an unassailable lead of 22 points.
OTHER RESULTS Nice secured three precious points in the race for European qualification with a 1-0 win against Montpellier. Brazilian defender Dante's goal in the 20th minute lifted the Riviera side to seventh place, just three points below fourth-placed Saint-Etienne.
Toulouse took a step toward safety with a 1-0 win against struggling Nantes. Issiaga Sylla scored the winner to help his team move four points above Vahid Halilhodzic's squad. It was Nantes' fourth consecutive loss in all competitions.
