|Close, day one: Yorkshire 299-3 v Durham|
|Yorkshire 2 pts, Durham 1 pt|
Yorkshire's Adam Lyth hit his first century of the season as the visitors seized the initiative on the first day against Durham at Chester-le-Street.
The left-hand opener made 104, sharing a stand of 179 with Kane Williamson, but both were dropped by the hosts.
Lyth departed immediately after tea, while New Zealander Williamson was later bowled by Chris Rushworth for 97.
Kumar Sangakkara, making his Durham debut, failed to hold an edge by Andrew Gale as Yorkshire closed on 299-3.
Yorkshire, beaten last week when Middlesex chased down a target of 472 to win by seven wickets, had England pair Jonny Bairstow and Tim Bresnan back in their side and opted to bat first.
Jamie Harrison accounted for Alex Lees, but Lyth and Williamson soon looked in full control.
Lyth could have gone on 88 when neither Scott Borthwick nor Paul Collingwood could hang onto a slip chance off Mark Wood and he went on to reach his ninth first-class hundred off 171 balls.
He was eventually taken at second slip off Harrison (2-87), before Wood was unlucky again when diving wicketkeeper Phil Mustard gave Williamson, on 92, a life.
The chance was not costly, however, as Rushworth found a way through to hit Williamson's off stump, but Durham could not separate Gale (35 not out) and Bairstow (22) in the final overs before stumps.
BBC Radio Leeds' Dave Callaghan:
"This was a good effort from Yorkshire's batsmen, although Durham did not help their cause by dropping catches.
"Full marks to Adam Lyth, for his sparkling innings, and Kane Williamson, who have set up an encouraging situation for their side.
"It was not a good day for Durham's bowlers despite a hearty effort and Andrew Gale and Jonny Bairstow will be hoping to cash in on the second day."
