Heliovaara and Patten had won 23 of 27 matches through Madrid, claimed four titles including the Madrid Masters on clay, and have won all four matches in straight sets at Roland Garros.

Now the second-seeded pair face their biggest test on Parisian dirt, a French Open semi-final against home favourites Halys and Herbert.

• Competition: Roland Garros 2026, Men's Doubles Semi-Final
• Venue: Roland Garros, Paris, France

Halys/Herbert vs Heliovaara/Patten Form and Head to Head

These two pairings have met once before, and it was a comfortable affair for the second seeds.

Heliovaara and Patten won 6-3, 6-4 in the Paris Masters semi-finals last November, wrapping things up in 69 minutes without ever looking troubled.

Heliovaara and Patten's run to this semi-final has been ruthless. Wins over Borges/Zhang (6-3, 6-3), Bellucci/Marozsan (6-1, 6-4), Goransson/King (6-3, 6-4) and Balaji/Demoliner (6-3, 6-4) tell the story of a pair in total control. No tiebreaks, no third sets, no drama.

Halys and Herbert have had a more eventful path to the last four. They needed three sets to get past Bonzi/Jacq in the first round (4-6, 6-3, 7-5) before finding their rhythm with straight-set wins over Harrison/Skupski, Droguet/Gaston and Arends/Pel.

Their tiebreak win against Harrison/Skupski (6-4, 7-6) showed they can handle pressure, though those closer encounters hint at a vulnerability the top seeds could target.

Herbert's Pedigree Meets Patten's Momentum

Pierre-Hugues Herbert is no stranger to the Grand Slam doubles stage, with multiple major titles on his CV. His experience could prove invaluable with a raucous French crowd behind them. 

Halys, primarily a singles competitor, has brought energy and purpose to this unlikely partnership.

On the other side, Heliovaara and Patten are building something special.

Titles at the Australian Open and Wimbledon already sit in their cabinet, and a Madrid clay-court triumph in May suggests the surface holds no fears.

With tennis playing styles explained by their aggressive serving and net play, Heliovaara and Patten have been clinical throughout the fortnight.

Halys/Herbert vs Heliovaara/Patten Prediction: Our Pick

Heliovaara and Patten look poised to reach their first Roland Garros final with a straight-sets victory.

The numbers are hard to argue with. A 23-4 record through Madrid, four titles, and four straight-set wins at this tournament without conceding more than four games in any set. 

They've already beaten this exact pairing 6-3, 6-4 in Paris, and their clay-court credentials were rubber-stamped with the Madrid title last month.

Herbert's Grand Slam know-how and a partisan crowd will lift Halys and Herbert, but there's a significant gap in quality and cohesion between these two teams.

The French pair needed three sets to get past Bonzi and Jacq in the first round and were pushed to a tiebreak by Harrison and Skupski, which hints at a ceiling that Heliovaara and Patten can exploit.

Expect a professional, efficient performance from the second seeds in two sets.
