Guilherme Valdoleiros v Robin Bertrand

Match preview, prediction and odds

Our pick

LeanWON
R. Bertrand to win1.01
Price too short today - wait for 1.09 or bigger · our chance 92% · market 9/91, us 8/92

R. Bertrand is 7-3 over the last ten and 1-7 on clay this season. G. Valdoleiros is 0-9 over the last ten and 0-1 on clay this season.

The pick is R. Bertrand to win. We make it a 92% chance, so it is only worth backing at 1.09 or bigger. At 1.01 that is not there yet - leave it, or wait for the price to drift in-play (an early break against usually does it).

An opinion from the numbers, not a guarantee. 19+, bet responsibly.

Ranking points fall off a year after they are earned, so a player who went deep here last year must match it or drop in the rankings. That shapes effort in a way the price does not always show.
