Beatriz Haddad Maia - Shuai Zhang: our prediction

Beatriz Haddad Maia is the favorite with odds of 1.7, and she has a 50% win percentage as a favorite, compared to Zhang's 60%. However, Haddad Maia has a better record in 2 sets (80%) and has won 30% of her recent matches, against 20% for Zhang. Additionally, Haddad Maia has a 100% win rate when favored with odds between 1.0 and 1.2, showing her ability to handle pressure. Zhang has a high loss rate (80%) and has lost 1 set as a favorite in 70% of her matches, indicating fragility. Haddad Maia seems more solid for this qualification match.

Statistics show that Haddad Maia finishes 80% of her matches in 2 sets, and Zhang 60%. As a favorite, Haddad Maia has an 80% rate of matches in 2 sets, while Zhang has 50% in 2 sets and 50% in 3 sets. Given that Haddad Maia is the favorite and has a strong tendency to win in 2 sets, and Zhang has a high loss rate (80%), it is likely that the match will end in 2 sets. Additionally, both players have a low percentage of matches in 3 sets (20% for Haddad Maia, 40% for Zhang). The bet 'Under 2.5 sets' is therefore consistent with Haddad Maia's victory.

With a high probability that the match ends in 2 sets (under 2.5 sets), the total number of games should be relatively low. On average, a match in 2 sets can have between 12 and 24 games, but with Haddad Maia as favorite and Zhang's high loss rate, it is plausible that the match will be dominated by Haddad Maia, limiting the number of games. For example, scores like 6-3, 6-2 would give 17 games. However, there is uncertainty because Zhang could take a set, increasing the number of games. The confidence level is therefore medium.
