GLAMORGAN need seven wickets on day four of their LV= County Championship clash with Leicestershire to boost their promotion bid.

The Foxes ended the third day in Cardiff on 75-3 in pursuit of 324 as Glam eye a fourth victory on the bounce.

With the weather set fair they should wrap up a success that will keep the heat on second-placed Surrey, who eased to a crushing win against Derbyshire on Tuesday.

A flurry of runs from the Glamorgan tailenders earned them a handy advantage to do the spade work for the victory in the evening session at the Swalec Stadium.

A smart catch by wicket-keeper Mark Wallace off Craig Meschede accounted for opener Angus Robson for 8 and then Graham Wagg bowled Ned Eckersley for 9.

Former Glamorgan favourite Mark Cosgrove joined opener Matt Boyce and the pair went along cautiously, attempting to make it through to the close.

But Cosgrove didn't look comfortable and his distinctly average season continued when he was trapped leg before for 14 by fellow Aussie Michael Hogan with five overs remaining.

Leicestershire were 60-3 but nightwatchman Jigar Naik and Boyce survived and the visitors, needing 249 more, will need their lower order to thrive like Glamorgan's.

The hosts made a patient start with Jacques Rudolph and Colin Ingram taking their third-wicket partnership to 96 before seamer Ben Raine gave Leicestershire a real sniff with a stunning spell.

Ingram fell for 60 when caught behind by Niall O'Brien and that combination was repeated when Chris Cooke went for 8.

Raine then trapped Meschede leg before and then bowled Wallace in a spell of four wickets for the cost of two runs in 17 deliveries – Glamorgan had gone from 97 for 2 to 105 for 6.

The hosts needed a partnership and they got one with Rudolph, whose slow scoring had added to the pressure, joined by Wagg, who thankfully added some oomph.

They added 54 before Wagg was bowled for 32 by Charlie Shreck with the lead at a still perilous 184 and the captain's incredibly patient innings ended on 74 when he played on to Tom Wells.

That led to the ninth-wicket pair of Andrew Salter and Hogan having a heave to provide plenty of entertainment and take the game away from the increasingly dispirited Foxes.

The latter fell to Shreck for a 27-ball 37 but Salter continued the assault by smashing the next ball over the ropes for his third six and he recorded his maiden first-class half-century.

The spinner, allocated to Newport in the Premier League this season, was left unbeaten on 54 when Andy Carter was caught by Cosgrove for 10 with the total on 298.
