Fair game spread: Riera by about 2.5 games; fair total 20.5 games. From an exact model of tennis scoring (points, games, tiebreaks, sets) fed the win chance above, fitted to the real game counts of recent WTA matches on clay, with room for the day's form, so blowouts and long matches show up about as often as they really do.

No line on this page yet. Sportsbooks price most tour matches once the order of play is out; we take a snapshot of tennis lines only when our shared odds budget allows. Game spread: "-3.5" wins if that player takes at least 4 more games than the other over the whole match. Total games counts every game, a tiebreak as one. If a player retires, most books settle the moneyline once a set is complete but void the spread and total; rules differ, so read your book's.

Advantages Why Julia Riera can win

  1. Better on clay: a clay-court rating of 1558 to Zarazua's 1516
  2. Higher rating for this match: 1560 to Zarazua's 1549 (every tour result since 2010, weighted by who it came against, with clay counting extra)
  3. Simulation: Riera wins in straight sets 39% of the time

Disadvantages Why Julia Riera may not

  1. Zarazua · Stronger overall record: an all-surface rating of 1582 to Riera's 1561
  2. Zarazua is seeded 2; Riera is unseeded
  3. One break of serve can decide a set, and a tiebreak is close to a coin flip
  4. Injuries and retirements: about one tour match in 35 ends with a player quitting mid-match, and how a bet settles then depends on the sportsbook's rules
  5. Conditions: wind, heat, altitude, a new ball or a night session can change how a match plays
  6. Ratings lag: a player coming back from injury or on a sudden run is rated on older results
  7. Upset odds: Zarazua wins about 1 time in 2, and takes at least a set 61% of the time
