Resuming on the fourth morning at 124-2, Albert and Jake Lehmann played conservatively for 40 minutes before switching up the gears as they took 12 off a Kellaway over.

Zain Ul Hassan’s first ball of the day was hoisted for six by Albert, but the seamer bowled Lehmann for 36 before limping off.

Off-spinner Kellaway benefited from the extra risks being taken, having Albert caught at deep mid-wicket while Ben Brown chipped a return catch after a chirpy cameo of 30.

But the captain chose to bat on until lunch and Neal took full advantage of the time offered, smashing four sixes and four fours in a display of clean hitting.

He was in line to break Liam Dawson’s county record of 22 balls for a Championship fifty until he lofted former Hampshire man Mason Crane to mid-wicket, prompting Brown to call a halt.

Crane was on emergency opening duty straight after lunch with Ul Hassan injured, and he lost partner Asa Tribe to the third ball, bagging a pair as Abbott had him lbw.

Crane did not last much longer as he fended Jack to third slip, while Kiran Carlson lost his off stump to an Abbott rocket and Glamorgan were 14-3.

Kellaway and Colin Ingram were starting to dig in, although Ingram was fortunate to survive two deliveries from Abbott that went over the stumps, when the predicted wet weather arrived.

The umpires decided the light was bad enough to come off at 14:47 BST and torrential rain started moments later.

An early tea was taken, but with pools of water on the covers, there was no chance of Hampshire resuming their push to win, with just under two days’ play possible across the four scheduled.

Glamorgan travel to Somerset on Wednesday, 2 September while Hampshire host Warwickshire, with only two days between the Championship rounds.

Glamorgan coach Richard Dawson told BBC Sport Wales:

“That first day was quick-moving with two bowling attacks that bowled well in challenging conditions, then we’ve had (bad) weather, and Hampshire got that total today and put us under pressure. Some of the bowling from Kyle Abbott, Eddie Jack and Sonny Baker was really good.

“There’s been a lot of things going on over the last two weeks, weather, stuff outside and we might just have taken our eye off what we’ve done well in the first eight games.

“We’ve had a chat about not looking too far ahead, looking at the table. We need a re-focus, so we start putting those periods of the game together that served us well. We know what we need to do.

“Zain felt something in his groin, it’s soon to tell but we’ve only got two days turnaround. It’s a tough schedule. Andy Gorvin’s still recovering from his back last week, Jamie McIlroy’s still recovering, Connor O’Riordan the same, there’s a few plates being spun.”

Hampshire captain Ben Brown told BBC Solent Sport:

“It was a classic back end of the season week really. A lot of time lost in the game, we got ourselves in a winning position and the weather won the day.

“We played pretty well. Bowled out for 160 was probably a par score (in the first innings), it was doing a fair bit, but with our batting we’ve got to get better. If we find a way to 250 there we put them under pressure.

“The bowlers did a fantastic job and the batters learned their lessons from the first innings and got us in a really good position to win the game.”
