Our pick
LeanJ.J. Wolf is 5-5 over the last ten and 21-10 on hard this season. J. Boulais is 4-6 over the last ten and 33-26 on hard this season.
The pick is J.J. Wolf to win. We make it a 79% chance, so it is only worth backing at 1.27 or bigger. At 1.24 that is not there yet - leave it, or wait for the price to drift in-play (an early break against usually does it).

Head to head
This season & this event
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.
