Jonny Bairstow marked his recall to the England team with an unbeaten 74 to give Yorkshire a seven-wicket win over Worcestershire at Scarborough.
Bairstow, who has replaced county team-mate Gary Ballance in the squad for the third Ashes Test against Australia, also made 139 in the first innings.
Ross Whiteley's 101 helped the visitors to 306 all out in their second innings, leaving Yorkshire 157 runs to win.
The hosts were 44-3 but Bairstow and Alex Lees (58no) saw them home.
Together, they shared an unbroken fourth-wicket partnership of 113 to maintain their side's unbeaten record in Division One this summer.
The defending champions remain top of the table, with a game in hand on their closest rivals, as they bid to retain their title.
Worcestershire moved out of the bottom two courtesy of their five bonus points, but are still in relegation trouble.
Resuming 71 runs ahead on 221-6, Joe Leach and Jack Shantry offered left-hander Whiteley good support as he moved to his third first-class century off 137 balls.
But left-arm seamer Ryan Sidebottom trapped Whiteley lbw with his first ball of the day and later bowled Charlie Morris to leave Yorkshire a modest victory target.
Opener Will Rhodes chipped a catch to mid-on to give Saeed Ajmal a wicket before lunch, while Morris removed Jack Leaning in the second over after the resumption.
And when Yorkshire's other first-innings centurion Andrew Gale was run out for four, Worcestershire - who had been forced to follow on in the match - sensed an unlikely win.
However, in-form Bairstow and Lees both hit half-centuries to guide Yorkshire to a seventh win in 10 matches this season.
Bairstow's 51-ball knock included nine fours and three sixes and he is now just 20 runs short of 1,000 in the Championship in 2015.
Yorkshire coach Jason Gillespie:
"I am very pleased to come away with full points, but this was still not our best performance, I have to acknowledge that.
"We had one big partnership in the first innings and a century stand in the second but we have still not nailed our partnerships.
"It is a nice position to be in at the top of the table, but there is still a lot of cricket to be played and we have six games remaining. The race for the Championship is not over yet and we can only control what we do and not what other teams do.
"It was another great knock from Jonny Bairstow. We all wish him well and hope he scores lots of runs for England. The ball is in his court and I am delighted he has got his opportunity."
