|LV County Championship Division One, Hove|
|Sussex 295-2 v Yorkshire|
|Sussex 2 pts|
Luke Wells hit his third County Championship century of the summer as Sussex dominated the first day against Yorkshire at Hove.
Murray Goodwin also reached three figures as, after being put in, the home side ended the day on 295-2.
Wells (143 not out) and Goodwin (108 not out) came together 10 minutes before lunch.
And they batted through two full sessions in an unbroken third-wicket stand of 217.
Wells, son of former Sussex skipper Alan Wells, who played one Test match for England, was only opening because Ed Joyce is away playing for Ireland.
But he enhanced his reputation as one of the best young batsmen in the country with a third ton in only his eighth Championship game.
Yorkshire skipper Andrew Gale probably felt a pitch with an even covering of grass would assist his seam attack.
And Ajmal Shahzad, one of the contenders to replace James Anderson in the England squad for the Lord's Test, did take the scalp of the in-form Chris Nash in the ninth over with one which nipped back.
Joyce is due back in time for the third day but his nominated substitute Joe Gatting struggled to take his chance.
Gatting failed to score off 40 of the 44 balls he faced before he drove loosely at Steven Patterson and was well caught by the diving Joe Sayers at cover. But that was as good as it got for Yorkshire.
Sussex are giving Championship debutants to two South Africans.
Left-armer Wayne Parnell, who only arrived at breakfast time on an overnight flight from Johannesburg, replaced Pakistan's Rana Naved as overseas player, while all-rounder Kirk Wernars, who qualifies because of his Dutch passport, was also included.
