County Championship: Anuj Dal steers Derbyshire to huge lead over Glamorgan

But there are signs of the ball keeping low to make Glamorgan’s survival bid more difficult.

The overnight pair of Came and Madsen looked fairly untroubled against Glamorgan’s seamers despite another tight spell from Timm van der Gugten, taking their stand to 130 on a bright and breezy morning.

But Kellaway clung on to a ferocious return catch to dismiss Came for a solid 84, while Madsen reached 70 but mistimed an attempt to hit Kellaway over the top and holed out for 70.

That brought the Welsh pair of David Lloyd and Aneurin Donald together, with the latter’s rapid cameo of 28 ended by a brilliant leg-side catch by keeper Chris Cooke, anticipating a paddle shot.

Dal could have been run out before lunch, but added useful runs for each wicket down the order after former Glamorgan captain David Lloyd (44) was bowled by a Crane googly.

Once Zak Chappell went for 29, Dal did his best to take the strike, but although last man Pat Brown shared in a stand of 48, there was no effort to maximise the time available for their bowlers and Dal was eventually caught in the deep off Crane as he tried to reach his century with a six.

That left Glamorgan just 12 overs to negotiate, with first-time opener Kellaway edging through slip for his first Championship runs.

Billy Root was dropped at slip off Chappell, and that proved Derbyshire’s last opportunity as Kellaway got a few fluent drives away to ease his nerves.
