Kevin O'Brien admitted he could not believe what he had done after his explosive innings powered Ireland to a shock victory over England at the World Cup.
O'Brien hit 113 off 63 balls as Ireland chased down 328 for a three-wicket win in Bangalore.
The associate nation set all kinds of records in the process - O'Brien's 50-ball century was the fastest in tournament history and 328 the highest run chase.
"I'm pretty speechless at the moment," O'Brien told Sky Sports.
"To be honest it's the best innings I've ever played since I started playing cricket.
"I just kept going and kept believing and it went our way."
O'Brien put on 162 in 17 overs with Alex Cusack (42) to turn the tide after Ireland had slipped to 111-5 in the 25th over.
"When we were 111 for five we could have just pottered around, but I chanced my arm and we didn't look back really," he said. "We attacked and it came off."
Cusack added: "I'm pretty amazed, words can't described how I'm feeling, just on top of the world.
"I was just trying to knock it around for Kev because he's got the power. He's got the big shots."
Ireland captain William Porterfield, who was dismissed first ball in his side's reply by James Anderson, hailed the victory as their greatest ever win.
"It's got to be the greatest, pretty much the greatest days of our lives so far," he said.
"Credit to the lads, they kept believing. We'll be looking to put in a performance like that every game."
