|LV County Championship Division One, Scarborough|
|Close of play, day one: Sussex 335-5 v Yorkshire|
|Sussex 3pts, Yorkshire 1pt|
Sussex skipper Mike Yardy and Ben Brown both made centuries as the visitors recovered well at Scarborough to post 335-5 against Yorkshire.
Sussex looked in trouble when Ryan Sidebottom reduced them to 27-3.
But, aided first by opener Ed Joyce (45), Yardy led the recovery with an unbeaten 126.
Yardy then put on 198 for the fifth wicket with Brown, who became Sidebottom's fouth victim for 108, as Sussex ended the first day in control.
Yorkshire were captained by South African Jacques Rudolph in the absence of Andrew Gale, who is out for the remainder of the season with a broken forearm.
And also missing from their line-up was Ajmal Shahzad due to an ankle injury.
But Sidebottom's magnificent opening spell got the relegation-threatened Tykes off to a great start, picking up three wickets for seven runs in his first spell.
He struck twice in as many balls when the score was on 15, Chris Nash falling lbw and Luke Wells being neatly taken by Anthony McGrath at second slip.
Murray Goodwin denied Sidebottom the hat-trick with a defensive push but soon afterwards he was unable to avoid contact with one which moved away from him and McGrath held on to another well-judged catch.
Just before lunch Joyce was caught behind, but wicketkeeper-batsman Brown joined Yardy and the pair stamped their authority on the game by dominating proceedings in the afternoon session as the pitch flattened out.
Yardy sailed past his previous best score this season of 63, compiled in his last innings against Worcestershire at Horsham, and at tea he stood on 79 with Brown on 52.
Brown then seized the initiative after the interval and was first to three figures, his fourth first-class hundred.
Yardy then moved to his 16th century by nudging a single in Sidebottom's first over with the new ball, which came at 265-4 in 80 overs.
But, after setting the highest sixth-wicket stand ever achieved at North Marine Road, Brown drove loosely and was caught behind.
