Alviro Petersen and Ashwell Prince broke a number of batting records with a 501-run stand as Lancashire’s cricketers declared with 698 for five on the second day against Glamorgan at Rhos-on-Sea.
The Lancashire bowlers - led by 41-year-old Glen Chapple - made good use of scoreboard pressure to make inroads into Glamorgan’s top order and, by the close, the Red Rose county had played themselves into a winning position.
Both batsmen achieved career best scores, and among the most notable records they created were the highest partnership in for any wicket in Lancashire’s history, the second highest in the County Championship, and the first time for two batsmen to score double centuries in the same innings.
Petersen scored 286 and was only 23 runs away from equalling Steve James’ highest score on the Colwyn Bay ground before he struck David Lloyd’s medium pace to long off.
Earlier Prince, who is unlikely to return next year, had struck 35 boundaries and seven sixes in his 261 before he was out 24 hours and two minutes after Karl Brown had been dismissed on the first day.
The carnage continued as Steven Croft blasted an unbeaten 57 from 51 balls, before Lancs declared on 698 for five thanks to a total of 85 fours and 12 sixes at the small ground with one six narrowly missing a bus outside.
Glamorgan, who required 549 to avoid the follow on, would have liked to have seen Jacques Rudolph emulate his fellow South Africans, but after striking seven boundaries he was undone by Chapple, who clipped his off stump.
Yet another South African - Colin Ingram - was also undone by Chapple, who soon reduced Glamorgan to 60 for three when he bowled Chris Cooke offering no stroke .Ten runs later Will Bragg, who had on driven James Faulkener to the boundary from the previous ball, attempted to repeat the stroke but was adjudged leg before.
Mark Wallace and Lloyd shared an useful 64-run partnership for the fifth wicket but Arron Lilley - in his first over - then dismissed Lloyd who was caught at backward point.
Glamorgan’s dismal day continued when Craig Meschede, who struck two sixes, chipped Simon Kerrigan to mid on as Glamorgan closed on 165 for for six, trailing to a massive deficit of 533.
