'Very sad' Sinner withdraws from Madrid Open with hip injury

"Very sad to have to withdraw from my next match here in Madrid," Sinner wrote on X. "My hip has been bothering me this week and has slowly been getting more painful. Taking the advice from the doctors we decided it's best to not play further and make it worse." Sinner's withdrawal came just minutes after world number three and two-time defending champion Carlos Alcaraz was knocked out in the quarter-finals by Andrey Rublev. Italian Sinner, 22, who was making his third appearance in Madrid, holds a 28-2 record on the season.
