Cardiff (day 2 of 4): Warwickshire 421 (I J Westwood 176, A G Botha 62, R D B Croft 4-101) v Glamorgan 183-5 (G P Rees 77).
A big hundred by Ian Westwood and three wickets from James Anyon put Warwickshire firmly in charge at the end of the second day of their LV County Championship Division Two encounter against Glamorgan at Cardiff.
Westwood, the stand-in captain, batted for nearly eight hours for his 176 to help Warwickshire to 421 in their first innings before Glamorgan, needing 272 to avoid the follow-on, were reduced to 118 for three by Anyon.
By the close the home side were 183 for five needing 89 more to ensure Warwickshire batted a second time.
Westwood carried on where he left off on the first day when he batted for six hours 13 minutes to be 139 not out overnight.
With Tony Frost, Westwood extended the fifth-wicket partnership to 76 until the wicketkeeper was caught well low down at second slip.
Westwood and Ant Botha took their side to two more batting points before the left-handed opener was caught by Alex Wharf diving forward at mid-off in Jamie Dalrymple's second over.
Westwood batted for seven hours 40 minutes, having faced 337 balls and hit 21 fours.
Robert Croft dismissed both Neil Carter and Chris Woakes leg before. And Botha's innings came to an end when he was run out from a direct hit by David Hemp, before Anyon was last man out.
The follow-on figure should not have really concerned Glamorgan, even though they came into the match on the back of two innings defeats at the hands of Northamptonshire and Leicestershire.
But thanks to some good accurate bowling from Anyon the home side slipped from 57 for nought to 118 for three either side of tea.
Just before tea Warwickshire broke through when Matthew Wood was caught by Michael Powell at third slip to give Anyon his first scalp.
Anyon struck again when he had David Hemp, the former Warwickshire left-hander, caught at first slip by Jonathan Trott.
At the other end Gareth Rees continued to ride his luck hooking consecutive balls from Carter for four.
A cut to the point boundary off Anyon brought up Rees' 50 from 77 balls, with six fours and one six, out of 94 for two.
But Anyon's nagging line bore him more fruit in the form of Michael Powell, who he trapped leg before to give his side a bowling point and leave the home side 118 for three.
Rees looked well set for a second century of the season before he danced down the track to Trott and was bowled off a bottom edge.
Four overs before the close Dalrymple edged Woakes to first slip to leave the home side 177 for five.
