Glamorgan laid the foundations for a serious push for a third successive County Championship victory on a rain-affected second day of their fixture with Warwickshire at Edgbaston.

Rain returned to wipe out the last 25 overs with Warwickshire struggling on 123-6 after the visitors’ seamers, led by Timm van der Gugten (2-21) and Zain-ul-Hassan (2-41), exploited perfect conditions on a damp day in the Second City.

Glamorgan were earlier bowled out for 360, a satisfying total from the travails of 0-2. Olly Hannon-Dalby took the last two wickets to finish with 5-53 and continue his excellent form since his recall from a surprise loan spell at Worcestershire.

Glamorgan resumed on the second morning on 341-8 and Mason Crane (20 not out) and Tom Norton (29) took their ninth-wicket alliance to a valuable 46 in 13 overs before the former’s off-stump was struck by a beauty from Hannon-Dalby.

The seamer then completed the 17th five-for of his career when Ryan Hadley left one that hit off-stump.

After a two-hour rain break, Warwickshire began their reply under heavy cloud and openers Alex Davies and Rob Yates worked hard to add 27 from 12 overs before the latter was lbw to a big inswinger from Ul-Hassan.

Davies (30) flicked two leg-side half-volleys from Ul-Hassan over the short boundary into the Hollies Stand but the bowler’s revenge arrived when an attempted drive ended in the hands of Sean Dickson at gully.

Dan Mousley (30) and Sam Hain batted diligently to add 35 in 10 overs but both departed due to injudicious leaves. Mousley’s off-stump was hit by Norton and Hain fell lbw to Van der Gugten.

After further rain, Glamorgan struck twice more in the gloaming as Van der Gugten trapped Ed Barnard lbw and Zen Malik edged Hadley.
