Wallace went on to complete a 41-ball fifty before being caught behind against Dominic Read - the younger brother of Glamorgan's Mike - when his side were one run short of the century mark. Marcus North attempting to maintain the tempo by driving Glamorgan old boy Mike O'Shea straight for six, but he departed next over as he was caught and bowled by Park. Jim Allenby got off the mark with a six against O'Shea before pulling Park for four. Allenby swept the spinner again for six over the pavilion before unleashing a pair of withering straight drives against the seam of Robert Woolley as together with Chris Cooke, the fourth wicket pair further improved Glamorgan's position with Cooke unleashing a brace of powerful drives through the covers en route to a 48-ball half-century.
Their aggression saw Glamorgan to the 200-mark in the 31st over to provide the prelude for a late run spree with Cooke reverse-sweeping and pulling O'Shea for a pair of fours before Allenby completed his fifty from 40 balls with a massive sweep for six. He celebrated with a pair of flowing sixes against Park, before Cooke hit the spinner for another straight six, followed by another booming drive for four before the batting powerplay was taken as the seam of Devon Endersby and Reed returned.
But Cooke responded by flat-batting the former for four, followed next ball by a sizzling drive through the covers for four before being bowled by a slower ball from Reed two short of a deserved hundred. Allenby responded by blasting another huge drive for six against Endersby before being caught by Scott Elstone at long-on in the final over. Murray Goodwin was also caught off the penultimate ball as Reed ended with the excellent figures of 5/31.
The Welsh county then claimed an early wicket as Michael Hogan removed Tom Lancefield who was caught behind in the second over. Fellow opener O'Shea responded by lofting Graham Wagg for six as well as driving him for four before being caught by Goodwin as he tried another expansive blow in Wagg's next over.
Simon Jones and Allenby then kept things tight with an accurate spell in tandem. Park and Elstone tried their best to keep up with the ever-rising run rate before Hogan returned to dismiss Elstone for 48. Park continued to work the ball around, besides striking the occasional boundary, but the accurate Dean Cosker, who had kept things tight in a series of probing overs, duly gained his reward as he dismissed Park for 74, courtesy of a good catch by Wagg.
Marcus North also ran out Vishal Tripathi before having Keith Parsons caught by Wagg, who proceeded to claim three wickets himself as the Unicorns tailenders continued their quest, albeit in a losing cause. They ended on 215/9 as Glamorgan maintained their quest of a semi-final place in the 40-overs competition, besides improving their net run rate by recording their first-ever victory over the Unicorns, with the only downside in the contest being an injury sustained by North which forced him off the field during his fourth over.
