Glamorgan 198 for 3 (Ingram 101*, Rudolph 49) beat Sussex 180 for 6 (Wright 101) by 18 runs
A record-breaking century by Colin Ingram at Arundel on Sunday propelled Glamorgan to their first victory in this season's NatWest T20 Blast.
Glamorgan, who were beaten by Hampshire in their opening fixture on Friday, beat Sussex by 18 runs, despite the almost equally violent Luke Wright equalling Ingram's score of 101.
Ingram's century was the fastest in the county's history in this competition. He reached his hundred from just 46 balls, and there were eight fours and seven sixes. He and Jacques Rudolph put on 130 from only 71 balls, a third wicket record for Glamorgan and their third highest for any wicket.
"I'm not too fazed by records," he said. "But it was nice to get a win under our belts in this competition. It was a beautiful day, a good crowd, a good wicket and I just went out there and enjoyed the conditions. "
Glamorgan had made a slow start to their innings, with just eight runs coming from the first four overs, by which time they had already lost two wickets..
Danny Briggs had Aneurin Donald lbw, sweeping, in the third over and in the next David Lloyd played on to Jofra Archer as he swung to leg.
The first four did not arrive until the fifth over, when Ingram got Chris Jordan away to the fine leg boundary. And it was only in the seventh over, bowled by Nash, which went for 14, that the innings really got going.
Sussex had varied their attack cleverly, with six different bowlers involved in the first nine overs. But once Ingram and Rudolph got into their galloping stride there was little any of them could do. The 11th over, from Briggs, went for 18 as Ingram raced to his fifty from 25 balls.
Sussex almost dismissed Rudolph in spectacular fashion when David Wiese, on the leg-side boundary parried the ball but it fell just short of he supporting fielder Wright.
Rudolph fell to a skier off Chris Jordan for 49 but Sussex could find no way to stop Ingram, now joined by Chris Cooke, as the pair put on an unbroken stand of 61 in 4.3 overs. When the 18th over, bowled by Archer, went for 19, Glamorgan looked likely to top 200. They fell just two runs short.
The Sussex innings, just like Glamorgan's got off to a stuttering start. Nash had his off-stump knocked back by Michael Hogan for a run-a-ball 12 and then Stiaan van Zyl was lbw to the same bowler, first ball.
Sussex suffered an even heavier blow when captain Ross Taylor, who looked in good touch with a six and a four in his brief came, top-edged Marchant der Lange to fine leg for 17, heaping even more pressure on Wright. When Ben Brown skied Colin Ingram to deep mid-wicket for 14 Sussex 97 for 4 in the 12th over.
Sussex needed a daunting 70 from the final five. When Hogan went for 16, with Wright thumping successive deliveries for six and four, it looked on. But Sussex's chances disappeared when Wright fell for a 53-ball 101, with five fours and seven sixes.
