There was a rare moment of light relief for Hampshire at the Rose Bowl yesterday.

With Hampshire following on Jimmy Adams drove Michael Kasprowicz to the long on boundary - and he and Derek Kenway managed an all run five as Robert Croft huffed and puffed his way to the rope.

Other than that there was nothing to laugh about.

Hampshire ended the second day 138 runs behind Glamorgan's 437 with six wickets in hand after being asked to follow on.

An inevitable 13th successive championship match without a win, a dismal run stretching back to last August, will surely follow unless wet weather saves the hosts from a second Frizzell loss in a row.

The day began okay when Dean Cosker edged Dimitri Mascarenhas to second slip after the Welsh county had added only one run to their overnight 436-9.

But then Hampshire's batting frailties were once again all too evident.

Jimmy Adams had his helmet broken by a Kasprowicz bouncer during the early stages of the first of his two scores of 21 (he was out in the tenth over of both innings).

Adams was fit enough to carry on but he edged the Australian to Mark Wallace shortly after Kasprowicz switched to bowling round the wicket to the left hander.

Within two overs Simon Katich edged his compatriot into the cordon, where third slip Matthew Maynard took a diving catch.

Then Kenway departed - the third Hampshire wicket to fall in seven overs - after having his off stump flattened by Alex Wharf.

The procession continued in the seventh over after lunch when John Crawley prodded Croft to short leg and Nic Pothas soon followed, trapped leg before by a ball that kept low.

John Francis, one of five Hampshire players to reach the twenties but not progress in the first innings, showed some grit, facing 94 balls for his 27.

But Wallace held on to a juggled catch at the wicket to signal the arrival of debutant Havant all rounder Richard Hindley.

The 28-year-old struck one boundary, steering David Harrison through mid wicket for four, before he was caught down the leg side after gloving a ball by the same bowler.

Mascarenhas was caught at second slip in Harrison's next over and then Chris Tremlett and James Bruce, who hit sixes over extra cover and long on off Croft, added 29 for the ninth wicket.

Tremlett was caught by a diving Wharf at gully and then Tomlinson was beaten for pace as Kasprowicz claimed his second five-for of the season.

Glamorgan skipper Croft surprised no-one when he asked Hampshire to follow on 252 runs behind.

Then the Welshman put his side on the threshold of their fourth championship win of the season - they entered this match having won three out of their last four - by taking all four of Hampshire's second innings wickets to fall.

Adams and Kenway got Hampshire off to a flier before the former was caught behind in the seventh over.

Kenway was the next to go, bowled around his legs as he attempted to sweep, and then skipper Crawley came down the wicket and was stumped in the 18th over.

Katich showed how it should be done, racing to his fifty off just 49 balls, scoring eight boundaries, before he swept the last ball of the day down the throat of long leg.

At the close Hampshire were 114-4, still needing 138 runs to make Glamorgan bat again.
