1.58
Confidence
High
Under 2.5 sets in the match
Both players have an 80% rate of matches ending in 2 sets in non-Grand Slam tournaments. Although Roland Garros is a Grand Slam, the data in Grand Slams is insufficient (0 matches for Guo, 1 for Costoulas). However, the general trend shows that these players often finish their matches in 2 sets. The odds of 2.24 for under 2.5 sets are attractive.
1.53
Confidence
High
Under 22.5 games in the match
With a high probability that the match ends in 2 sets (under 2.5 sets), the total number of games should be under 22.5. The odds of 1.58 are in line with this trend. However, confidence is medium because Grand Slam matches can sometimes be tighter and go to tie-breaks, which could increase the number of games.
