Surrey 374 for 6 (Burns 90, Roy 87, Sangakkara 82*) vs Yorkshire
Surrey, led by half-centuries for Rory Burns, Jason Roy and Kumar Sangakkara, dominated the opening day of their pink ball Specsavers County Championship match against Yorkshire at Headingley.
Having opted to toss, as was the trend with away teams around the country, and elected to bat, the visitors piled on 374 for six from 96 overs.
Below par Yorkshire failed to gain any control for the two sessions as Roy, in particular, took the attack to them either side of lunch in this historic day/night fixture.
After a difficult Champions Trophy campaign, the 26-year-old looked in supreme touch for 87 off 91 balls.
Having hit 92 in the recent Royal London Cup semi-final win over Worcestershire as well as 67 in the T20 international against South Africa at Taunton, this knock included eleven fours and two sixes.
Despite it being his first Championship appearance of the season, it marked his third successive 50 plus score in this competition.
In a defeat against Durham at Emirates Riverside last September, he posted scores of 120 and 96.
Opener Burns top-scored with 90 off 186 balls, while Sangakkara added 82 not out off 124.
Tim Bresnan claimed his 500th first-class wicket for Yorkshire in front of a 2,595 crowd, including 494 after 4.40pm when reduced ticket prices were in operation.
Roy came to the crease with Surrey at 75 for two after 21 overs, with Mark Stoneman hitting 30 and Scott Borthwick 31 - both men looking in good order and showing signs of the visitors positive approach.
Roy and opener Burns, the anchor for the innings, shared 147 inside 33 overs for the third wicket before the former was lbw to Jack Brooks as the score fell to 222 for three in the 54th.
He reached 50 off 54 balls and hit his two sixes straight into the Football Stand off England team-mate Adil Rashid, who conceded 67 in 12 overs.
Roy was promoted to bat at number four ahead of Sangakkara, who settled quickly during the second half of the afternoon and hit Rashid over long-on for six with his 19th ball at the crease.
Earlier, Stoneman was caught behind driving at Ben Coad in the eleventh over having hit his previous two balls for four, while Borthwick chipped Steve Patterson to mid-wicket.
Yorkshire's fourth wicket, that of Burns in the final over of the afternoon, came as the left-hander was undone by extra bounce from Bresnan, who had him caught behind for his 500th - 271 for four in the 64th over.
Yorkshire at least managed to get some kind of control in the first half of the evening session, with Surrey scoring 38 runs in 16 overs before the second new ball to take the score to 309 for four after 80.
And it did the trick as Coad had Ben Foakes caught at cover for 23, leaving the score at 320 for five in the 83rd.
Sangakkara later reached 50 off 86 balls to add to the one-day century he scored here earlier this month, but he lost Sam Curran in the 91st over when he was caught behind off Patterson with 358 on the board.
Bresnan will captain Yorkshire in the second half of this match when Gary Ballance leaves for Lions duty. Harry Brook has been named as his replacement.
