Vasek Pospisil added a second upset to his US Open tally on Saturday, recovering from two-sets-to-one down to shock Roberto Bautista Agut 7-5, 2-6, 4-6, 6-3, 6-2 on Louis Armstrong Stadium.

The World No. 94 struck 70 winners and came to the net on 45 occasions to break through Bautista Agut’s defence and reach the Round of 16 in New York for the first time. The victory comes five years after Pospisil’s maiden run to the fourth round at a major championship, when he advanced to the 2015 Wimbledon quarter-finals.

“[I am] thrilled. I was playing great tennis all the way through,” said Pospisil. “I had a little bit of a physical dip in the second and third sets and then the shade came in, which really helped me… I played solid all the way through. I was very relaxed, going for my shots and sticking to my game plan, my strengths. It worked out really well.”

Pospisil has now defeated two of the most in-form players since the resumption of the ATP Tour on Louis Armstrong Stadium. Two days ago, the 30-year-old came from a set down to defeat Western & Southern Open runner up Milos Raonic in four sets.

Pospisil entered his fourth ATP Head2Head match against Bautista Agut without a win to his name, but the Canadian raised his game in the final two sets to overpower his opponent. Pospisil improves to 11-5 this year, building on a strong start to the season prior to the suspension of the ATP Tour in March. More than five years after reaching his maiden ATP Tour final in 2014, Pospisil advanced to his second ATP Tour championship match at the Open Sud de France in February.

Pospisil will face Alex de Minaur for a spot in the quarter-finals. De Minaur also rallied from two-sets-to-one down to overcome 11th seed Karen Khachanov 6-4, 0-6, 4-6, 6-3, 6-1. The Aussie broke serve on six occasions to book his place in the US Open fourth round for the second straight year after three hours and two minutes.

De Minaur is unbeaten in two ATP Head2Head meetings against Pospisil. The Sydney native claimed hard-court victories against Pospisil in 2018 at the Citi Open in Washington, D.C. and the Rolex Shanghai Masters.

After nine games without a break point, Bautista Agut attacked Pospisil’s forehand to survive two set points at 4-5. But the Canadian, who won 10 of 13 net points in the first set, quickly created another opportunity in his next return game. Pospisil ripped his three consecutive forehand winners to break to love at 5-6 and snatch the opening set.

Pospisil survived seven break points in his opening service game of the second set, before Bautista Agut charged back into the match. The nine-time ATP Tour titlist attacked his opponent’s backhand and moved to the net to earn his first break of the match and quickly doubled his advantage en route to the second set.

Bautista Agut made a quick start to the third set, playing with consistency from the back of the court to extract errors in in the opening game. The World No. 11 held his advantage with confidence on serve, winning 87 per cent of points behind his first delivery to move one set from victory.

Pospisil landed 20 winners in the fourth set, including a backhand return winner at 4-3, to force a decider and charge to the finish line. The Canadian moved up the court in crucial moments in the fifth set and showcased composure at the net to gain two service breaks. Serving for the match at 5-2, Pospisil converted his first match point with a pinpoint backhand passing shot up the line.

As the old adage goes, a match isn’t over until the last point has been played. Neither Borna Coric or Stefanos Tsitsipas will likely forget that again after their captivating and dramatic third-round match on Friday at the US Open.

Coric, the No. 27 seed, saved six match points, including three in a row with Tsitsipas serving at 5-4 in the fourth set, en route to producing a jaw-dropping 6-7(2), 6-4, 4-6, 7-5, 7-6(4) win over the fourth seed. He moved to 6-4 in five-set matches, while Tsitsipas dropped to 1-3 after suffering one of the most heartbreaking losses of his career.

“I have to be honest and say that I was really lucky. I made some unbelievable returns and I was a little bit lucky at the end,” Coric said. “In the third and fourth set, he was playing unbelievable tennis and I felt like I had no chance. In the fifth-set tie-break, I knew it was not going to be easy for him, so I tried to just keep the ball in court and make him play as many balls as possible.”

The 23-year-old Croatian produced another great escape 48 hours earlier in rallying from two-sets-to-one down to defeat Juan Ignacio Londero. Although Coric’s results have been inconsistent and he came to the match with a 7-6 record this year, his win against Dominic Thiem at the ATP Cup reaffirmed that he has the game to beat anyone when he’s at his best.

Next up for Coric is Jordan Thompson, who defeated Mikhail Kukushkin 7-5, 6-4, 6-1 to reach the second week of a Grand Slam for the first time. Coric has matched his best result at a Grand Slam and now seeks his first quarter-final at a major championship.

There was little separating Tsitsipas and Coric in the opening set, eventually leading to a tie-break. With Coric serving at 2/3, Tsitsipas adjusted his strategy and began moving forward behind high-octane groundstrokes. The strategy rattled Coric and the Greek grabbed the last four points for an early lead.

Coric took a medical timeout after the tie-break and received treatment on his neck and right shoulder. The medical attention appeared to help his serve and he held with ease throughout the second set, winning 80 per cent of serve points (20/25) compared to 66 per cent (23/35) in the opening set. He stayed with Tsitsipas and took advantage of a brief dip in form from the fourth seed at 4-5, breaking serve and leveling the score after the Greek fired a forehand well long.

Although both players traded comfortable service holds throughout the third set, the physically punishing baseline rallies appeared to take a toll on Coric. Tsitsipas continued to apply pressure and attack any short balls that came his way. He was rewarded for his persistence and let out his biggest roar of the night after breaking Coric to love at 4-4, then won six of the next seven games to grab the third set and build a 5-1 lead in the fourth set.

But with victory in sight, the fourth seed let slip his first chance to serve out the match and squandered two match points on Coric’s serve at 5-3. Four more match points came and went at 5-4, including three in a row at 40/0. Tsitsipas pointed at his head in disbelief, then looked at his team with a wry smile after finally handing another break to the Croatian with a backhand error.

Energised by the miraculous comeback, the 23-year-old began swinging freely from the baseline and dominating their exchanges. With Tsitsipas serving at 5-6, Coric cracked a forehand return winner on set point and pumped his fist after leveling the match.

Even when the Greek broke for a 3-2 lead in the final set, Coric remained calm knowing he had experienced much worse. He immediately broke back in the next game with a forehand passing shot, then saved three break points for a gutsy hold at 4-4.

Tsitsipas only hit one double fault across 29 service games, but hit two in the final-set tie-break. The costly errors helped give Coric a 6/3 lead and he converted on his second match point after a forehand error from the fourth seed wrapped up play after four hours and 36 minutes.
