Why the Odds Changed

Recent Developments
Casper Ruud and Joao Fonseca are preparing for what is shaping up to be one of the more extended early-round contests at Roland Garros, with their May 31 meeting expected to feature at least 41 completed games across the match.
Ruud, a proven clay-court performer and former Roland Garros finalist, will face a rising challenge in Fonseca, whose baseline power and confidence have made him a dangerous opponent on slower surfaces. The matchup points toward multiple competitive sets, with both players likely to find enough service holds and momentum swings to push the total deep into the match.
Official Grand Slam statistics will determine the final count, with tiebreaks counted as one game. If the contest plays out as anticipated, fans in Paris can expect a physically demanding encounter that tests endurance as much as shot-making.
