Sri Lanka shattered the one-day world record by piling up 443-9 in their 195-run win over the Netherlands.
Sanath Jayasuriya hit 157 off 104 balls and Tillakaratne Dilshan 117 not out in Amstelveen as they beat South Africa's 438-9 against Australia in March.
Medium pacer Peter Borren came in for the harshest punishment as he marked his ODI debut with 1-94 from 10 overs.
Seamer Dilhara Fernando and leg-spinner Kaushal Lokuarachchi took three wickets each as the hosts were all out for 248.
Sri Lanka began the two-match series by winning the toss and although they lost Upul Tharanga for 18 when he was bowled by New Zealand-born Darron Reekers, the boundary count was soon climbing steeply.
Skipper Mahela Jayawardene made a bright and breezy 34 off 24 balls before he was caught off Ryan ten Doeschate, who normally plies his trade in English county cricket with Essex.
And Jayasuriya and Kumar Sangakkara then put on 149 for the third wicket before Sangakkara (46) became the first of two victims for another Dutch debutant, Mohammad Kashif.
The 21-year-old slow left-armer also ended Jayasuriya's onslaught by bowling him with the total on 291, an innings which features a six and 24 fours.
But that merely cleared the way for Dilshan, who dominated the rest of the innings by hitting two sixes and 14 fours while facing only 79 deliveries.
Kashif (2-79) and Billy Stelling (2-77) were the most successful bowlers and there was some relief for Borren when he took a return catch offered by Lasith Malinga as four Sri Lanka wickets went down in the last four overs.
The previous highest total conceded by The Netherlands was 328-3 against South Africa at Rawalpindi during the 1996 World Cup.
