Ashlyn Krueger - Mary Stoiana: our prediction

Ashlyn Krueger is the favorite with odds of 1.37, reflecting her seeded position in this qualifying match. Although her overall win rate is 40%, she has a 50% record as a favorite, while Mary Stoiana has a 60% win rate as a favorite but only 30% as an underdog. Krueger also has a better percentage of wins in 2 sets (60%) outside Grand Slams, which is relevant here as it's a best-of-2-set qualifying match. Stoiana tends to lose sets when favored (80% of her matches as favorite), which could play into Krueger's hands.

Statistics show that Mary Stoiana has a high rate of matches in 3 sets (60% outside Grand Slams), and when favored, this rate rises to 70%. Additionally, Krueger has a 40% rate of matches in 3 sets outside Grand Slams. Given that Stoiana is the underdog and Krueger tends to lose sets as a favorite (60% of her matches), it is likely the match will go beyond 2 sets. The odds of 2.87 for over 2.5 sets are attractive.

With a high probability of a 3-set match, the total number of games could exceed 22.5. On average, a tight 3-set match can reach 24-30 games. Krueger and Stoiana both have a high rate of 3-set matches (40% and 60% respectively), which supports this assumption. However, confidence is medium because 2-set matches can also be long, but the general trend points to a competitive match.
