Dominic Thiem vs John Isner: Prediction and Betting Tips

Dominic Thiem

After two matches in which Thiem won with relative ease against Marcos Giron and Alex De Minaur, the Austrian ATP number four is expected to face tougher opposition in what will be a real test for the one-time Grand Slam and 17 ATP tour winner.

This is considered to be a successful campaign so far for Thiem as he is just back from a knee injury and hasn’t played since he lost to South African Lloyd Harris in the second round of the Dubai ATP Tour back in March.

John Isner

The American world number 39 had two great wins en route to the Quarter-Finals, first against clay-court specialist Roberto Bautista Agut in the second round and then in the third round, John Isner overcame one of the most in-form players on Tour Andrey Rublev.

The big-serving 15 time ATP title winner played five tiebreakers so far in Madrid winning four and losing one. He has hit a whopping 89 aces in the tournament and was broken just twice in three matches.

Key Stats

• John Isner has hit on average 29.7 aces per game while Thiem has hit 4.5 Aces per game
• Both players were broken twice in all of their matches
• Isner has hit on average 56.3 winners per match while Thiem won 59 points with clean winners in his two matches
• Isner has won 82% of points behind his first serve while Thiem has won 75% of his points behind his first serve

Dominic Thiem vs John Isner Prediction

Both of these players are playing very well this week in Madrid. Isner has relied on his serve in the three matches he played and the fact that he could send five sets into tiebreaks is a sign that he is not broken very often.

Thiem has to come up with answers to Isner’s serves. The Austrian will definitely control the rallies but the American will try to keep them short and go for big shots. Thus it is important for Thiem to make the best out of Isner’s second serve.
