Derbyshire 98 for 2 (Slater 41*) trail Glamorgan 377 (Palladino 5-83) by 279 runs
There was time for Tony Palladino to pass another noteable milestone and Michael Hogan to strike two quick blows for Glamorgan before rain cut short the second day of the game at Derby.
Derbyshire seamer Palladino took his tenth five-wicket haul for the county and the 12th of his career before Timm van der Gugten and Andrew Salter revived Glamorgan by adding 63 in 15 overs. Hogan then removed Chesney Hughes and Hamish Rutherford but Ben Slater and Wayne Madsen prevented further setbacks until the rain arrived and wiped out the final session.
Batting was more demanding than on day one and Glamorgan's lower order crumbled in the face of some fine bowling by Palladino, who struck in consecutive overs.
Luke Fletcher made the first breakthrough, defeating Craig Meschede's drive without addition to the overnight score, before Palladino got one to lift sharply at Graham Wagg, who was well caught by Hughes at first slip. When Hogan's attempt to clear the ropes ended in the hands of Rutherford back-peddling from mid-off, Glamorgan had lost three wickets in four overs for six runs but Derbyshire were frustrated by a tenth-wicket stand that secured a fourth batting point.
The bitterly cold conditions made bowling difficult for legspinner Matt Critchley, who was twice dispatched for six by van der Gugten, the second landing on the roof of the pavilion. The Netherlands seamer also hit four fours before he edged Wes Durston low to slip.
Derbyshire's reply was briefly halted by a sharp shower but Slater and Hughes profited from some loose bowling until Hogan broke through from the Racecourse End.
Hughes had his off stump knocked back as he aimed an expansive drive with little foot movement and Rutherford also contributed to his own downfall six overs later. The New Zealand international lifted a short ball from Hogan over the slips but only picked out Salter at third man, where he took a well-judged catch just inside the ropes.
Madsen did well to survive his first ball, which reared unpleasantly, but Glamorgan could not maintain the pressure as the third-wicket pair added another 40 runs before the rain clouds rolled in.
