Glamorgan 330 for 3 (Rudolph 169*, Rees 60, Goodwin 59) beat Sussex 323 for 3 (Wright 127, Finch 92*) by seven wickets

Jacques Rudolph eclipsed a superb hundred by Sussex's Luke Wright with an even better one of his own to ease Glamorgan to victory in their final Royal London game at Hove.

Rudolph made a career best 169 to guide his side to a seven-wicket win as they chased down a Duckworth-Lewis adjusted target of 329 with eight balls to spare. Rudolph's innings was also the highest score in List A matches by a Glamorgan batsman, beating Sir Viv Richards' 162 against Oxfordshire in 1992.

Wright had earlier taken full toll of some wayward Welsh bowling to score 127 from 115 balls - his second century in four days - before Rudolph shredded the Sussex attack to score his third century in this season's competition.

Rudolph was on 131 when he made his only blemish, but Yasir Arafat dropped a difficult return catch in his follow-through as he tried to intercept a waist-high straight drive. Otherwise, Rudolph gave a masterclass in timing and placement as he followed earlier hundreds against Somerset and Nottinghamshire to take his competition aggregate to 575 runs.

On a superb pitch, a weakened Sussex attack, which included 18-year-old Academy product Fynn Hudson-Prentice on his debut, found there was no margin for error.

Rudolph lost opening partner Jim Allenby, who was caught and bowled by Lewis Hatchett, in the seventh over but he ticked over at a run a ball thereafter to ease to the 16th List A century of his career.

Gareth Rees helped him set up victory with a second-wicket stand of 173 in 26 overs before Rees was sent back by his partner looking for a single into the leg side and beaten by Ed Joyce's throw.

It gave the hosts a glimmer of hope but that was soon extinguished by former Sussex player Murray Goodwin, who took four boundaries off Hatchett in an over during the second power play as he raced to a 26-ball half-century.

Arafat had Goodwin lbw playing across the line for 59 in the 44th over after a partnership of 100 in 10.3 overs for the third wicket, but Glamorgan needed just 25 more at that stage and Rudolph fittingly hit the winning runs with his 17th boundary. He also struck three sixes in the 150 balls he faced.

Wright certainly did not deserve to be on the losing side after scoring his fifth hundred of the season in all cricket to take his aggregate in the one-day formats to 993, as Sussex piled up 323 for 3 from 48 overs. He also became the first Sussex batsman to score a hundred in all three formats in the same season. It was a chanceless ninth List A hundred of his career and also his highest one-day score for the county.

Wright added 71 for the first wicket with Chris Nash and 99 in 18 overs with Craig Cachopa but the acceleration came when Wright and Harry Finch, in only his second List A appearance, plundered 79 in nine overs. Wright was eventually caught off a big top edge aiming to drive down the ground, having faced 115 balls with 14 boundaries and four sixes.

Finch upped the tempo and his unbeaten 92 contained 12 fours and two sixes as he plundered 71 from 55 balls in an unbroken fourth-wicket stand with Machan. However, in the end Sussex's highest one-day score against Glamorgan was not enough to subdue the peerless Rudolph.
