A cavalier 113 from Jason Roy was the highlight of a crushing 100-run win for Surrey over Scottish Saltires in the Yorkshire Bank 40 Group B match at the Kia Oval.
The 23-year-old completed his fourth list A hundred from just 77 balls and overall hit two sixes and 16 fours in his 86-ball innings as Surrey reached 303 all out from 39.1 overs before bowling Scotland out for 203.
Tom Curran finished with 5-34 from 6.1 overs and Zafar Ansari 4-42 as Scotland, given a decent start as openers Hamish Gardiner and Freddie Coleman put on 94 inside 18 overs, lost wickets in quick succession in a vain attempt to get close to Surrey's huge total.
Coleman made 53 before he was fourth out at 123, leg-before to seamer Curran, the 18-year-old son of former Zimbabwe all-rounder Kevin Curran. It was Curran's maiden senior wicket, in his second list A appearance, and he soon added the scalp of Moneeb Iqbal who was bowled for 16 as Scotland's slide continued apace.
Later Curran returned to bowl Majid Haq, Craig Wallace for a 20-ball 35 and Calvin Burnett to return the best figures by a Surrey bowler in the format for four years.
Left-arm spinner Ansari's victims were Richie Berrington, Calum MacLeod, skipper Preston Mommsen and Gordon Goudie for a duck. Both Berrington and Mommsen were caught by Curran.
Surrey face Somerset in the Friends Life t20 quarter-final on Tuesday and Roy, Steven Davies and Vikram Solanki appeared in fine fettle at the top of the order after winning the toss.
Davies pulled Haq's off-spin for two sixes in the sixth over and there was also an early maximum for Roy as he raced to fifty from 39 balls. The pair had put on 91 for Surrey's first wicket inside 11 overs when Davies was caught off fast bowler Goudie for 31.
Solanki hit a six and eight fours in his 63 from 47 balls, adding a further 126 in 14 overs for the second wicket with Roy, who completed his hundred in the 23rd over.
Both Roy and Solanki were caught at long-on attempting to hit seamer Burnett into the crowd and the rest of the Surrey innings fell away somewhat, with only Jon Lewis's 20-ball 25, a late six by Gareth Batty and a six-run penalty against Scotland for not bowing their 40 overs within a time limit taking them past 300.
Gardiner, a 22-year-old debutant, pulled Lewis for six and drove Batty over extra cover for one of his five fours in a promising 48 from 56 balls before being bowled heaving across the line at the latter’s off-spin. Coleman also batted well for his 53 off 71 balls with six fours.
Some late blows from Wallace and Burnett, though, were all that Scotland could offer as Curran and Ansari carved through the rest of their batting order, and the end came in the 36th over of their reply.
