Having won their First and Second Round matches in two sets, the Finn and Brit were back on the same side of the court today, after Patten and Olivia Nicholls had knocked Heliovaara and Anna Danilina out of the mixed doubles in the Second Round yesterday.
There was clearly no love lost between the pair, as they broke their opponents serve in the third game of the first set to take a 2-1 lead. Two games later, they broke again, showing plenty of resilience to eventually take a 4-1 advantage after three break points.
Having only dropped two points off their four service games, the pair strolled to a 6-2 first set victory in just 26 minutes.
In the second set, Bopanna and Pavlasek - both inside the top 40 of the men's doubles rankings - looked like a whole new duo, not conceding a single point from their first three service games. However, Heliovaara and Patten never came close to losing serve, either, and before long it was 5-5.
Both partnerships were too strong when serving again in games 11 and 12, as the second set inevitably headed for a tiebreak.
The first 11 points all followed the rest of the set by going with serve, but 6-5 ahead and thus the first match point, the number two seeds broke serve to take a 7-5 tiebreak win and a third straight-sets (6-2, 7-6) victory of the French Open.
The duo now move onto the Quarter-finals, where they will face the winners of the match between American pair Christian Harrison and Evan King and India's Yuki Bhambri and the USA's Robert Galloway.
