Wright's 113 guided the visitors to 230 which left Yorkshire to make 106 off 39 overs and they got there with 18.5 overs in hand.
The maximum 24 points that Yorkshire took out of the game gave them a six point lead over nearest rivals Nottinghamshire - one point more than before the match began.
The target was not large enough to pose any undue problems for Adam Lyth and Alex Lees as they set about their task and with Lees leading the way the openers had 50 up by the 12th over.
Lyth hoisted James Tredwell for a straight six, surprisingly only the second of the match, before both batsmen cleared the rope again against the off-spinner.
But in attempting one big hit too many, Lees smeared Matthew Hobden to Lewis Hatchett with the total on 88 and departed for 46 from 50 balls with four fours and a six.
Kane Williamson made sure the momentum was maintained with three consecutive boundaries off Hobden and at the close Lyth had made 39 and Williamson 15.
