Jannik Sinner's decision on whether to contest the Madrid Open is down to a physical assessment in Spain rather than tactics, according to reports from Rome. The world number one will land in Madrid this week after his Monte Carlo final against Carlos Alcaraz, but the Italian camp has kept the door open to a last-minute withdrawal depending on how he pulls up physically.
Italian daily Gazzetta dello Sport, via well-connected tennis journalist Jose Morgado, reported that Sinner will fly to the Spanish capital and then decide based on how he feels after a light week. The 24-year-old has played a heavy hardcourt swing into Monte Carlo with only short breaks, and team members have privately noted that the condensed 2026 calendar is offering less recovery than in past seasons.
The stakes for Madrid are unusually high. Sinner skipped the event in 2025, meaning any point he wins this year is a clean ranking gain. With Alcaraz reportedly nursing a wrist complaint and Novak Djokovic already out, the top half of the draw has thinned dramatically. Tournament organisers told local media they expect a Sinner confirmation by Tuesday.
Sinner's coach Darren Cahill has long argued for a more conservative clay approach in Grand Slam years, pointing to Rafael Nadal's rest patterns before Roland Garros. The Italian's race lead is comfortable enough that a Madrid absence would not materially shift the ATP standings, but the psychological impact of three straight Masters 1000 wins heading into Rome cannot be discounted either.
The clay swing has already been disrupted once, with 13 top names out of the tournament before a ball was struck. Jack Draper and Holger Rune followed Djokovic and Alcaraz in pulling out, while Stefanos Tsitsipas is carrying a back niggle that could yet add his name to the list. For the ATP, the concern is that the Masters 1000 model is starting to buckle under the physical demands of a longer, denser season.
Sinner's call will set the tone for the rest of the draw. A confirmation, which most inside the sport still expect, makes him a prohibitive favourite. A withdrawal would open the top half for Stefanos Tsitsipas or a surging Tommy Paul to make a genuine run at a Masters crown. Either way, Madrid's opening week just became the most-watched early-round stretch of the clay season.
