Glamorgan 20 for 0 trail Derbyshire 251 (Godleman 95, Wagg 3-36, van der Gugten 3-66) by 231 runs
Derbyshire captain Billy Godleman continued his recent impressive run of form with 95 to steer his side to respectability on the opening day of the Division Two match against Glamorgan at Derby.
Godleman, who had scored a century and 71 in his previous four innings, passed 4000 first-class runs for the county as Derbyshire made 251 with their former seamer Graham Wagg taking three wickets.
Timm van der Gugten also claimed three wickets and in reply, Glamorgan were 20 without loss when bad light ended play early.
Derbyshire's previous home game had been a batting feast with more than 1300 runs scored but conditions here provided help for the bowlers throughout with the floodlights on from ball one.
Given the overcast skies and a green tinged pitch, it was no surprise the toss was uncontested and Tom Lace had already been dropped in the slips before he shouldered arms and lost his off stump to one that came back a long way from van der Gugten.
van der Gugten also saw Wayne Madsen put down at point before he had scored in the same over but he clipped Michael Hogan tamely to mid-wicket and when Alex Hughes was caught behind trying to withdraw his bat, Derbyshire were wobbling at 50 for 3.
Godleman was beaten several times but showed typical determination along with an awareness of any movement in the media centre to ensure his team posted what looks a competitive total.
Gary Wilson shared a stand of 52 but was lbw playing no shot to the last ball of the morning to give David Lloyd his 50th first-class wicket and Matt Critchley batted positively until he played across the line at Hogan.
Kieran Bull, in his first game for three years, was rewarded for an impressive spell of controlled offspin when Harvey Hussein was lured down the pitch and after tea was taken early because of rain, former Derbyshire allrounder Wagg had Martin Andersson lbw on his Championship debut following his loan move from Middlesex.
Godleman had been in for 270 minutes but with a century beckoning, he dabbed at a wide ball from Wagg and was caught behind.
Wagg quickly pinned Lockie Ferguson lbw but Tony Palladino and Ravi Rampaul guided Derbyshire to an unlikely second batting point before Glamorgan were left with 13 overs to negotiate.
It was always likely to be an awkward period for the openers but they survived six overs before bad light ended play with Glamorgan 231 runs behind.
