Set Handicap: Value On The Line

In the set handicap market, Rublev is tasked with laying -1.5 sets. Carrying 19 career ATP titles and a career-best ranking of 5, Rublev has consistently proven he can sweep through opponents when firing. Gaston has shown positive recent form with consecutive victories over Sho Shimabukuro and Jaime Faria, but holding off a top opponent over multiple sets remains a steep challenge.

Rublev winning in straight sets rates a real chance based on their past meeting where Gaston failed to claim a set. Backing Rublev on the -1.5 set line at 1.7 is a big tick, while Gaston gets a start on the +1.5 set handicap at 2.1.
