Eoin Morgan was glad to find some form as his sensational century helped England to a six-wicket win over Ireland at Malahide.
Morgan hit an unbeaten 124 off 106 balls and was part of a 226-run stand with Ravi Bopara that rescued England from a perilous position at 48-4.
They eventually chased down a target of 270 for victory in only 43 overs and the England captain was pleased to be in the runs ahead of a five-game one-day series with Australia later this month.
"I was more nervous sitting in the changing room than I was out in the middle. I started to calm things down a bit when I got in, which was nice, and the wicket was as expected. It was quite tough, quite challenging, with the ball and the bat," Morgan said.
"It has been (frustrating) and today has been magnificent to get some runs under my belt and some time in the middle, and contributing to an England win which is fantastic.
"Time in the middle as a batsman is crucial, especially coming into a big series, and today I felt pretty good."
Morgan was on the end of one or two jeers from the largely Irish crowd, but he laughed them off and congratulated organisers for a wonderful spectacle at their new home just outside Dublin.
"It was an incredible day for Irish cricket, the support was magnificent, getting nine or 10,000 people to come out and support a fantastic cricket association, so congratulations to Cricket Ireland on a successful day.
"You only have to look around and see the crowd we had today, and the support they had, and we got the pleasure of meeting the president who popped in, which was fantastic. The support they've been getting for the last couple of years has been brilliant."
Boyd Rankin who, like Morgan, previously played in Ireland colours, was England's best bowler with figures of 4-46, and the captain paid tribute to the Warwickshire bowler's performance, which made up for the struggles of debutants Michael Carberry and Gary Ballance.
Carberry, usually one of the County game's best fielders, had a nightmare with two dropped catches, and he made only 10 runs opening the England reply, while Ballance was caught behind second ball for a duck.
"Boyd is quite used to conditions here, he had to go a bit fuller with his length which is quite challenging for a guy of his height, but he handled things well and has settled in really well," Morgan added.
"We played on a pitch we are not used to playing on, it was quite tricky to start with especially while the seam on the ball was still hard. Potentially there could have been some nerves there which is to be expected for the guys coming in."
