Glamorgan 237 and 74 for 4 (Thomson 3-35) lead Derbyshire 198 (Madsen 63, Lloyd 60, Crane 4-60) by 113 runs
Spin continued to dominate proceedings on the second day of the Vitality County Championship match between Glamorgan and Derbyshire in Cardiff.
Mason Crane took four wickets on his Glamorgan debut as Derbyshire were bowled out for 198, 39 runs behind on first innings. Wayne Madsen top scored for Derbyshire with 63 but his departure brought about a collapse of five wickets for 33 runs.
Alex Thomson was once again the star man with the ball for Derbyshire as he secured his first 10-wicket haul in first-class cricket. Glamorgan had reached 74 for 4 at the close, a lead of 113 with six second innings wickets in hand.
With the pitch offering significant assistance to both seam and spin bowlers the destination of this game will depend on how well Glamorgan bat in the first session of day three.
Having resumed on 46 for 1, Derbyshire while placed to get past Glamorgan's total and they started the day with captain David Lloyd reaching fifty from 65 balls against his former county. He was the first wicket to fall on day two when he was trapped lbw by Crane for 60.
Harry Came made a patient 25 from 113 balls but he never really found runs easy to come by on a pitch that is slow enough that batters had to take risks to score quickly. He was dismissed by James Harris for the second of his three wickets in Derbyshire's innings. Harris conceded runs at less than 1.5 an over, conceding just three boundaries, one of which was an edge past the slips as he finished with figures of 3 for 28.
As was the case in Glamorgan's first innings, it was the spinner who was the most consistent threat with Crane starring with the ball on his Glamorgan debut. Figures 4 for 60 was his best return in first-class cricket since his five-wicket haul against Lancashire for Hampshire in 2021.
While Crane was a consistent threat, it was the seamers who took the heart out of the Derbyshire batting line-up with Dan Douthwaite and Mir Hamza picking up wickets.
While Madsen was at the crease it felt as is Derbyshire could claim a first-innings lead but when he was well caught in the covers by sub fielder Asa Tribe off Douthwaite it began the collapse that prevented Derbyshire eclipsing Glamorgan's first innings total.
Crane was brought back into the attack after a short break and claimed the last three Derbyshire wickets as scoring became increasingly difficult against the aging Kookaburra ball. When the last Derbyshire wicket fell on the stoke of the tea break Glamorgan had secured a 39-run lead.
When their second innings got underway the Glamorgan openers once again found Thomson extremely difficult to face. Having claimed career-best figures of 7 for 65 in the first innings he opened the bowling and had two wickets in two balls. Both Zain-ul-Hassan and Sam Northeast were dismissed lbw, the latter for a golden duck.
Thomson claimed his 10th wicket of the match when he bowled Kiran Carlson for 11 before Sam Conners bowled Billy Root for 32 to put this game into the balance heading into the third day.
