Insert preview here opposing Serena in some capacity in round 1 given the question marks around her fitness.
In all seriousness though, this is just a 0.75 unit selection on Siegemund to get the jump on Serena. Whilst I generally prefer to take Siegemund over the three sets in matches involving her, my preference changes here with Serena across the net at grand slam level.
If you are on Serena for any futures, you are about to get a fantastic gauge of how she is physically. Siegemund will make her use every inch of the court, and although she said her shoulder was the issue for the withdrawal the other day, I think there may still be a small underlying concern with her achilles.
Suggested Bet
0.75 units Siegemund first set winner at $4.50 (+350) at Bet365
