Singh and Dockrell set a world record to slay the Knights
A world-record seventh-wicket partnership in List A matches and the best bowling figures in the 50-Over Inter-provincial Cup eased Leinster Lightning to an emphatic 53-run victory over Northern Knights.
Simi Singh, who will hope to be named today in the Ireland squad for next week's T20 Tri-series in Holland, and George Dockrell put on an undefeated 215 - surpassing the previous best of 203 in Sri Lanka ten years ago - after the holders had slumped to 62 for six.
Yet, with small boundaries square of the wicket at Milverton, a target of 278 was achievable if Knights could bat out the overs.
But, not for the first time this season, the wickets ran out long before the finish as Dockrell sealed a memorable match by becoming only the second bowler to take five wickets in an innings, half as economical as Shane Getkate's 5-43 for Knights against Lightning at Belmont last year.
The Knights, though, will always insist that the record stand should have been halted at 57 when Singh, on 38, appeared to edge his YMCA team-mate Harry Tector into the hands of wicket-keeper Neil Rock.
Umpire Wijesundara, however, said 'no', much to the disbelief of the Knights fielders, and 16 overs later Singh was 121 not out - the third highest score in the competition, 15 short of his own best - and Dockrell was 98 not out, after only managing to hit the last ball of the innings for two.
Fittingly, it was Dockrell who took the final catch as Rock, who finished top scorer, perished in the chase for victory, albeit with 45 balls unused.
Knights had been helped by Getkate winning the toss on a green pitch, and by the end of his fifth over he had taken four wickets to put his side in control.
But, surprisingly, he introduced spin in the 24th over and the pressure was instantly released as Singh and Dockrell rebuilt the innings.
The visitors got off to their usual fast start but, once again, could not prevent wickets falling at regular intervals - five partnerships reached 30 but not one made 40 - and there was a dead heat between James Shannon and Getkate for the worst shot of the day to help Dockrell to his record figures.
