Fritz Headlines Bottom Half
Taylor Fritz lands in the bottom quarter alongside Alejandro Davidovich Fokina and rising Spaniard Martin Landaluce.
Ranked No. 3 in the Crush & Rush News Grass Court Power Rankings, Fritz owns one of the strongest grass résumés in the field after winning Stuttgart and Eastbourne and reaching the Wimbledon semifinals last season.
Bublik Draws the Toughest Quarter
If there’s a quarter to avoid, it’s Alexander Bublik’s.
The world No. 5 in the Crush & Rush News Grass Court Power Rankings shares his section with Tommy Paul, Giovanni Mpetshi Perricard, and Jan-Lennard Struff.
Perricard’s huge serve makes him dangerous on any grass court, while Struff is always a threat playing at home in Germany.
Lehecka Flying Under the Radar
Jiri Lehecka may be the most overlooked contender in the draw.
The Czech sits No. 9 in the rankings, one spot ahead of Shelton, thanks to his strong results at Queen’s Club and Wimbledon.
A potential quarterfinal against Frances Tiafoe could be one of the best matches of the week.
Kyrgios Returns in Shelton’s Section
The first-round headline matchup belongs to Nick Kyrgios.
The Australian returns to tour-level action and immediately faces Corentin Moutet.
Meanwhile, top seed Ben Shelton anchors the quarter and will be expected to make a deep run after climbing to No. 10 in the Crush & Rush News Grass Court Power Rankings.

The betting market views Ben Shelton as the player to beat in Stuttgart.
The interesting question is whether the betting market agrees with the latest Crush & Rush News Grass Court Power Rankings.
Not entirely.
While Shelton sits atop the odds board, Taylor Fritz enters Stuttgart as the highest-ranked player in the field in our grass rankings.
The defending champion is ranked No. 3 overall on grass, while Alexander Bublik checks in at No. 5 and Jiri Lehecka at No. 9. Ben Shelton ranks No. 10.
That creates one of the biggest differences between the market and the rankings.
The market is placing a premium on Shelton’s recent rise up the ATP rankings and his explosive serve, while the rankings place greater emphasis on proven grass-court success.
Fritz owns five career grass-court titles and returns as the defending Stuttgart champion, while Bublik remains one of the most dangerous players in the world on this surface.
Another interesting number belongs to Tommy Paul.
Paul is listed among the leading contenders at +750 despite ranking No. 44 in the latest Grass Court Power Rankings.
Meanwhile, Alejandro Davidovich Fokina (+1600) and Giovanni Mpetshi Perricard (+1600) sit much lower on the odds board despite stronger grass-court profiles than many casual fans may realize.
The biggest wildcard remains Nick Kyrgios at +2800.
No player in the field carries a wider range of outcomes. If healthy, Kyrgios has the serve and grass-court pedigree to challenge anyone in Stuttgart. If not, his tournament could be over before it begins.
From a rankings perspective, Fritz and Bublik appear slightly undervalued, while the market is asking bettors to pay a premium for Shelton’s upside and Paul’s overall ATP reputation.

Favorites vs. Underdogs Performance
The early rounds in Stuttgart have historically favored chalk, with favorites producing positive returns through the quarterfinal stage.
