Rain-delayed play brought renewed intensity and surprising results as action finally resumed at the Cincinnati Open, reshaping the tournament narrative heading into the quarterfinals.

In a weather-interrupted clash, defending champion Jannik Sinner edged qualifier Adrian Mannarino 6-4, 7-6(4) to maintain his title defense and extend his hard-court winning streak to 24 matches. Despite rhythm challenges, Sinner held firm in the pressure-fraught tiebreak, punching his ticket to the last eight.

Carlos Alcaraz was equally composed, powering past Hamad Medjedovic 6-4, 6-4 in a clean, straight-sets performance. The Spaniard, celebrating his 50th win of the season, handled the tricky conditions with authority, dictating play and capitalizing on key breaks in each set to move smoothly into the next round.

Other notable outcomes included Alexander Zverev, who completed a 6-4, 6-4 win over Brandon Nakashima after overnight suspension—setting the stage for a potential rematch with tournament nemesis Karen Khachanov

Amid the chaos of storm-delays and interrupted scheduling, the draw is now clear for the quarters: Sinner, Alcaraz, Zverev, Shelton—all favorites—remain on path. The day's results underline the importance of mental grit and adaptability—critical traits in this unforgiving Masters 1000 environment.
