Alexander Blockx vs Felix Auger-Aliassime Prediction
This Round of 32 clash at the Mutua Madrid Open pits the highly-ranked Felix Auger-Aliassime against the in-form clay-court player Alexander Blockx. Auger-Aliassime is the strong favorite, but Blockx's recent strong performances on clay suggest he could make this a more challenging match than the rankings imply.
ATS PREDICTION
Felix Auger-Aliassime Win
Predicted: 2-0 (7-5, 6-4)
60%
Felix Auger-Aliassime, ranked World #5, holds a significant advantage over Alexander Blockx, World #71, in terms of overall experience and skill. Auger-Aliassime demonstrated strong form in his Madrid opener with a dominant straight-sets victory, showcasing excellent serving and limited unforced errors. While Blockx has shown impressive recent clay court form with a 6-2 record on the surface this year and two wins in Madrid, including a three-set battle, Auger-Aliassime's elite status and ability to elevate his game in crucial moments are expected to prevail. Despite clay being Auger-Aliassime's least productive surface historically, his strong start to this tournament indicates he is playing well.
SPREAD PREDICTION
Alexander Blockx +3.5 (+3.5)
50%
Alexander Blockx has been performing exceptionally well on clay this season, securing two challenging wins in Madrid, including a three-set victory over Brandon Nakashima. While Felix Auger-Aliassime is the clear favorite, his historical performance on clay is less dominant than on other surfaces, and Blockx's recent matches suggest he can keep sets competitive. This spread offers good value, anticipating Blockx to either win a set or keep both sets close enough to cover the game handicap.
TOTAL PREDICTION
Over 22.5
50%
Given Blockx's strong current form on clay and his tendency to play longer, three-set matches in this tournament, there's a good chance for the total games to go over 22.5. Even if Auger-Aliassime wins in straight sets, a scoreline like 7-6, 6-4 would push the total to 23 games. Blockx's fighting spirit and Auger-Aliassime's less dominant clay record suggest a potentially close contest, increasing the likelihood of more games.

Betting Angles โ Alexander Blockx vs Felix Auger-Aliassime
โ Moneyline: Felix Auger-Aliassime
Despite Blockx's good clay form, Auger-Aliassime's World #5 ranking and overall skill level make him a strong favorite. The implied probability from the odds (69.9%) is lower than our model's probability (78%), indicating a solid edge for a straightforward win.
โ Game Handicap: Alexander Blockx +3.5
Blockx's demonstrated ability to keep matches tight on clay, as seen in his two Madrid wins, makes him a good candidate to cover a +3.5 game handicap. Auger-Aliassime's clay performance is not always his most dominant, and Blockx could push at least one set to a tie-break or take a set, leading to a close game count.
โ Total Match Games: Over 22.5
With Blockx's strong clay form and history of playing three-set matches in Madrid, combined with Auger-Aliassime's tendency for slightly less overwhelming victories on clay, the likelihood of more than 22.5 games is underestimated by the odds. A 7-6, 6-4 scoreline alone reaches 23 games.
๐ฐ Sharp Money
Sharp money is likely leaning towards Auger-Aliassime on the moneyline, but also exploring handicaps for Blockx and over totals given his recent competitive performances on clay. Line movement: Initial lines likely favored Auger-Aliassime heavily. We might see some slight movement towards Blockx's game handicap and the 'over' total as more bettors consider his recent clay court prowess and the potential for a more drawn-out match.
