Craig White hammered Yorkshire's first Championship century of the season at Canterbury yesterday before Amjad Khan brought home the Danish bacon for Kent.

The 21-year old Copenhagen-born paceman, playing in only his third first-class match, deservedly finished with figures of six for 52 as Yorkshire slumped to 239 all out.

It was another pitiful effort by the county champions who lost their last five wickets for seven runs in 13 overs and they would already seem to have it all to do to avoid their third consecutive defeat of the season.

There was plenty of swing in the air and Kent exploited it well but Yorkshire at the moment look incapable of stopping a collapse once it has started.

In their previous Championship game against Somerset their last eight second innings wickets tumbled for 94 runs and exactly the same happened again yesterday.

Apart from a cameo 42 from Gary Fellows, White was in a class of his own and he gave the England selectors another gentle reminder that he is still around.

Relishing his opening role, he struck the ball cleanly and scored heavily through the covers with some of his trademark shots but he was fortunate to get away with a hooked six off Mark Ealham, the ball landing just over the head of Khan, who had moved in a yard or so from the long-leg boundary.

White went to his century off 173 balls with 15 fours and a six but on 104 he pushed forward at the spin of left-armer Min Patel and was taken at slip. It was White's 11th century for Yorkshire and his third in his last five Championship matches.

Khan struck his first blow by getting sufficient away movement for Matthew Wood to edge a drive to David Fulton at first slip where he took an excellent catch, but it was Ealham who claimed the prize for the best wicket of the day from an inswinging, well-disguised slower ball which plucked out Michael Lumb's off-stump.

Darren Lehmann helped White add 79 in 24 overs to take Yorkshire to a healthy 145 for two, at which point Lehmann was lbw hitting across a straight one from Khan for 31 and a general malaise set in.

Fellows inspired hope of a recovery with some lovely strokes, particularly off his legs, but in trying to add to his tally of five fours and a six he took a step down the pitch at Patel and was bowled, the spinner and Khan then having little bother in disposing of the tail.

Kent were left with 14 overs in which to bat but neither Chris Silverwood nor Steven Kirby posed any problems.
