Second seed Daniil Medvedev continues his march towards a first major title as he defeated Dutch qualifier Botic van de Zandschulp 6-3, 6-0, 4-6, 7-5 in the US Open quarterfinals on Arthur Ashe Stadium.
World number two Medvedev comfortably claimed the first two sets with the loss of just three games combined before Van de Zandschulp began a mini-revival, taking the third set, the first qualifier to ever win a set in a US Open quarterfinal and pushing the Russian to 5-5 in the fourth.
Ultimately, Medvedev would prevail in two hours, 24 minutes to reach his third consecutive semifinal at Flushing Meadows where he will face 12th seed Felix Auger-Aliassime for a place in Sunday's final.
World number two needs four sets to dismiss talented Dutchman
The Russian struck immediately, breaking in the opening game of the match after Van de Zandschulp hit a forehand wide. Both men held until Medvedev extended his advantage with a second break.
Leading 4-1, the world number two gave one of the breaks back, but triumphed in a 14-point game that ended when the Dutchman was errant with another forehand, giving Medvedev a one-set lead.
The second set went by in a flash as Van de Zandschulp won just ten points in total, the world number two needing just 23 minutes to establish a two-set lead and the qualifier took an off-court break before the start of the third set.
The break seemed to re-energize the world number 117 as he held three break points in the opening game of the third set, but was unable to convert on any of them.
Finally, the Dutchman was able to breach the Medvedev serve, blasting a forehand down the line to take a 3-2 lead. He rode that advantage all the way through the set, clinching it when the Russian went long with a backhand.
Both players rolled through the fourth set on serve until Van de Zandschulp faced a match point, which he saved. Serving again to stay in the match, a failed drop shot on match point sealed a hard-earned win for Medvedev.
