Inzamam-ul-Hak suffered yet another batting failure for Yorkshire as the Championship leaders were again outplayed by Sussex, but the former Pakistan captain was not the only one to experience a miserable time of it.

After racking up their best-ever score against Yorkshire of 597 for eight declared, Sussex piled on the pressure in the field and by the close had their dispirited opponents struggling on 188 for seven, still 260 runs away from avoiding the possibility of the follow on.

The only happy news for Yorkshire on a glorious late summer's day was that captain Anthony McGrath awoke refreshed from a good night's sleep to report himself much improved after the previous day's fainting attack while standing at mid-off.

"I had felt unwell for a couple of days and I developed a bad headache as the day wore on," explained McGrath. "I was stood at mid-off and the next thing I can remember is being helped to my feet and led off.

"I was examined by a doctor who said my blood pressure was normal and that he did not believe it was anything serious. Perhaps I should have rested up earlier but with the responsibilities of the captaincy I did not really want to go off."

Sussex resumed on 386 for five and delayed their afternoon declaration until wicketkeeper-batsman Andrew Hodd had notched his maiden Championship century before falling to Adil Rashid for 123.

Rashid emerged with Yorkshire's best figures of three for 136 but newly-signed leg-spinner Imran Tahir conceded 141 runs without taking a wicket and one wonders how left-armer, David Wainwright, would have fared had he been included instead.

Yorkshire were in trouble as early as the fifth over when England captain Michael Vaughan sliced a drive at Jason Lewry and was well held to his left at gully by Michael Yardy.

Andrew Gale and McGrath took the score to 79 before McGrath's fluent 31 was ended the ball before tea by Mushtaq Ahmed who had him caught off bat and pad by Richard Montgomerie at silly point.

Inzamam was off the mark with boundaries either side of the wicket against his old friend and colleague Mushtaq, who was swift to gain revenge by getting him picked up by Chris Adams at slip in his next over.

In four consecutive innings since joining Yorkshire, Inzamam has made eight, nine, seven and eight. Rather than being at sixes and sevens he appears to be at eights and nines.

Casual strokes contributed to Yorkshire's further demise, Jacques Rudolph's cameo 23 ended by an edged drive off Robin Martin-Jenkins to Montgomerie at slip, the paceman striking again when Gerard Brophy drove low to cover.

Gale tried valiantly to hold things together and reached his first 50 of the season off 109 balls with six fours before he, too, had a rush of blood and was caught by Adams at slip as he advanced down the pitch.

Tim Bresnan perished in similar fashion to Mustaq but Rashid again showed his prowess as a batsman by finishing unbeaten on 32.

Mike Powell (82) and Jim Troughton (76) excelled in Warwickshire's total of 285 on the opening day of their match with Surrey at Edgbaston.

The visitors were 41 for one at stumps in their reply.

In Division Two, Nottinghamshire captain Stephen Fleming battered east midlands rivals Derbyshire for an unbeaten 217 from 239 balls at Chesterfield.

Former England wicketkeeper Chris Read also made 90 at Notts amassed an imposing 500 for six on the first day.

Promoted Somerset are favourites to win their clash with Essex, and clinch the title, after they reached 50 for one chasing a victory target of 182 at Chelmsford.
