THE Derbyshire bowlers did well to keep Glamorgan's batsmen under pressure on the opening day of their LV County Championship match at the Swalec Stadium.
But Chris Cooke, who made his maiden first-class century the previous week, held them up with 62 not out in a total of 191-6 at tea.
Chasing their fourth successive victory in the competition, Derbyshire lost the toss but bowled well and took three wickets each of the first two sessions.
But they only had the wicket of Jacques Rudolph for nine at the end of the 10th over to show for their efforts until shortly before lunch. He was lbw to the nagging Tony Palladino at 25-1.
Palladino and Mark Footitt passed the edge several times but it was not until the 26th over that Derbyshire had their second breakthrough, Wayne White switching to around the wicket and getting Will Bragg lbw for 22 at 68-2.
Wes Durston, having taken five wickets to close out the win against Worcestershire last week, was into the action after an hour and caused problems. He followed White's wicket with one of his own in the next over when Gavin Rees pushed forward and was bowled for 28 at 76-3.
Jim Allenby was caught at first slip off Footitt in the third over after lunch for six at 82-4 and David Lloyd gave David Wainwright a first wicket, caught at slip for 23, to make it 126-5.
Footitt returned to remove skipper Mark Wallace, who left a ball that bowled him for seven at 158-6, but Cooke and Graham Wagg looked to strike back before tea.
Cheteshwar Pujara came in for his Derbyshire debut, replacing Chesney Hughes in the only change to the side that beat Worcestershire.
