Yorkshire director of cricket Martyn Moxon has admitted he is concerned about the form of his bowlers following a second day of domination for Sussex in the LV County Championship.

The Tykes closed on 21 for none at Hove - in reply to their hosts imposing first-innings total of 548 for four declared.

"A couple of our bowlers are struggling a bit at the minute," said Moxon, after his side ended the day still 368 runs away from the follow-on target when bad light brought a premature end to proceedings.

"That is what happens with form, but it is something that we have very little time to work on. I think that you can see from the figures as to who is not in the best of form - but that is the game. All I would say is that people are trying hard to get it right."

Adil Rashid and Ajmal Shahzad are likely to be Moxon and the Tykes biggest worries. The duo, normally so potent with the ball, will want to forget their week on the South Coast so far.

Rashid ended with 0-187 when the declaration came, the third most expensive figures ever for the county, while Shahzad had recorded 1-145 by the time Sussex put the Yorkshire attack out of their misery.

Murray Goodwin did most of the damage - ending with the third highest individual score every posted against the White Rose to close on an unbeaten 274.

It was a brutal innings which contained 37 boundaries, as the Zimbabwean began the day by adding to his third-wicket partnership with Luke Wells. The two resumed with a stand of 217 - and continued on where they had left off on day one to end any hopes of an immediate Yorkshire comeback.

They passed the county's previous best third-wicket stand against the Tykes of 279 early on, before Wells was eventually out for 174 in bizarre circumstances when he was ran-out by Steve Patterson.

He lapped up the applause as he left the action - leaving Goodwin to blast his way to his mammoth total before his captain Michael Yardy decided the time was right to declare just before tea.

It was a dubious call, given that the Tykes looked down and out in the field, with his choice of timing then not helped by poor weather.

Yorkshire had only batted for 11.2 overs before play was called off, with Joe Root and Joe Sayers both making six runs to close on 21 for none.

It means the Tykes head into day three 527 runs behind Sussex's first-innings total.
