Colombian Miguel Angel Rodriguez celebrated his first Tour meeting with Mohd Ali Anwar Reda in the first round of the Delaware Investments US Open by beating the higher-ranked Egyptian in a dazzling performance in the fifth PSA World Series squash event of the year at Drexel University in Philadelphia.
Displaying some extraordinary running, retrieving, leaping, diving and unorthodox shot-making, the world No30 from Bogota got the better of Reda, ranked six places higher, in a magical five-game match.
It seemed that the 22-year-old from Cairo had weathered the storm as he edged the second to level the match and eased through the third.
But there was no stopping Rodriguez: "I particularly loved his 360-degree spins, and the drop shot he plays while running backwards, having dashed to the front after his opponent's high boast before engaging reverse gear," said event spokesman Steve Cubbins.
The Colombian went on to win 11-9, 11-13, 3-11, 11-5, 11-5 in 82 minutes to earn his first appearance in the last 16 of a PSA World Series event this year.
Event MC Bryan Ramona was also clearly impressed by Rodriguez: "We'll have to call you 'the Cat' after that display."
Rodriguez will now face Thierry Lincou after the sixth-seeded Frenchman dashed home hopes by beating New York-born wildcard Christopher Gordon 11-9, 11-5, 11-6.
But there was disappointment for Egypt's Karim Darwish when the second seed was forced to retire against Mohd Azlan Iskandar with an ankle injury. The Malaysian went into the match 8/0 down in a career head-to-head record since 2003 - but after leading 2/1 and 7-2 in the fourth, the Sarawak-born 29-year-old celebrated his maiden success when Darwish conceded the match.
Iskandar will now meet Nicolas Mueller after the Swiss number one became the only qualifier to claim a place in the second round when England's Jonathan Kemp was forced to pull out with a back injury.
US-based Australian number one David Palmer made sure of his last 16 place with a straight games win over fellow countryman Ryan Cuskelly. But despite coming through two tough qualifying matches, the world No42 put up a good show against experienced eighth seed Palmer, three times a finalist and winner of the US Open title in 2002.
"I knew he'd keep fighting," said Palmer after his 11-8, 11-9, 11-9 victory in 51 minutes. "I was a couple of points behind in the second but managed to his some winners at the end, which was crucial, and I probably relaxed a little after getting a good lead in the third, but I thought I played pretty well to get to that point.
"If he keeps on playing with an attitude like that, it will go well for him in the future.
"I can't afford long matches," added the former world number one. "At 35, I need to win 3/0 when I can, so it was good in the end and I'm looking forward to coming back tomorrow."
Palmer will now take on last year's runner-up Laurens Jan Anjema, the Dutch number one who defeated English qualifier Chris Ryder 11-6, 11-7, 11-5.
"Chris is very clever tactically," said Anjema. "So I had to try to get the upper hand early and try to put him under pressure physically.
"It was a bit too chaotic for my liking at times, but I'm happy with how I played and pleased to get off with a three-nil win."
Left-handers Amr Shabana and Adrian Grant will meet for the second time in 10 days when they line up in the second round. Fourth seed Shabana, the 2009 champion, came through against fellow Egyptian Wael El Hindi 11-7, 11-4, 9-11, 11-5, while Englishman Grant overcame Canadian qualifier Shawn Delierre 12-10, 11-5, 11-4.
"He's very unorthodox and hard to read - it took me a game and a half to work him out," admitted Londoner Grant after ending Delierre's run in his first World Series appearance since 2008.
"Once I found my feet I managed to present my game to him and I felt more and more confident," added Grant.
Shabana was meeting El Hindi for the 15th time on the Tour since 2001: "It's always difficult playing someone you know so well," said the 32-year-old four-time world champion. "Wael hasn't played a lot of squash in the last six months, and is just coming back, but he still made it pretty difficult for me at times."
