Hostile fast bowling by Chris Silverwood forced Northamptonshire to follow on 179 runs behind Yorkshire in the Cricinfo Championship match at Headingley on Saturday.

Northants were bowled out for 195 with Silverwood claiming five for 58, his second fifth wicket haul of the season.

Bowling flat out from the Kirkstall Lane end, Silverwood looked far sharper than either Matthew Hoggard or Ryan Sidebottom, and the only batsman to play him with any confidence was Russell Warren who finished unbeaten on 65.

Warren came in at 40 for two and held firm for four hours and 22 minutes while wickets fell around him, facing 190 balls and striking six fours.

He had one piece of luck on 19 when he was put down at slip by Craig White off Gary Fellows.

Northants got into trouble despite a career-best bowling performance earlier in the day from seamer Darren Cousins who captured eight for 102, easily beating his previous best first class effort of six for 35 for Essex against Cambridge University seven years' ago.

Cousins grabbed all five Yorkshire wickets to fall today at a personal cost of 28 runs in 9.5 overs. Among his victims was Michael Lumb who hit a career-best 50 off 119 deliveries with seven fours and a six.

Yorkshire were all out for 374, Richard Blakey remaining unbeaten with a coolly struck 42.

Mike Hussey and Mal Loye had six overs to survive when they went in for a second time and they put on nine together without being parted, leaving Northants to make a further 170 to make Yorkshire bat again.
