Match preview, prediction and odds

Our pick

Lean

Y. Watanuki to win1.16

Price too short today - wait for 1.18 or bigger · our chance 85% · market 83/17, us 85/15

Y. Watanuki is 7-3 over the last ten and 14-13 on hard this season. M. Imamura is 3-7 over the last ten and 42-29 on hard this season.

The pick is Y. Watanuki to win. We make it a 85% chance, so it is only worth backing at 1.18 or bigger. At 1.16 that is not there yet - leave it, or wait for the price to drift in-play (an early break against usually does it).

Did not play

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.
