Set Handicap Analysis

The line market is set at -1.5 sets, with Fonseca on the negative line at 1.70 and O'Connell offered at 2.10 with a +1.5 set start. A big tick for O'Connell is his resilience in tough spots; all three of his recent victories went the full distance of three sets.

Fonseca also has a pattern of long contests recently, having dropped sets in his last start against Shelton and his victory over Ruud. Given O'Connell's ability to battle through three-setters, pushing the higher-ranked Brazilian in a close match rates a real chance.
