Balcombe puts Hants in charge
David Balcombe took five Glamorgan wickets to put Hampshire in control on the first day of their rain-interrupted Division Two clash.
Balcombe recorded figures of five for 33 to go with his match figures of 11 for 119 against Gloucestershire last week.
He was denied a sixth wicket as Glamorgan declared their first innings on 103 for nine during the last of three breaks for rain in a bid to try to make inroads into the Hampshire batting in the final hour.
The tactic paid some dividends as Huw Waters had Jimmy Adams caught behind as Hampshire finished on 29 for one, 74 behind.
Glamorgan's batting woes continued after their consecutive defeats to Leicestershire and Derbyshire.
Despite winning the toss and electing to bat, Mark Wallace's men found themselves 68 for five at lunch after a useful display by Hampshire's five-prong attack.
The Welsh county had made a patient start before Stewart Walters attempted an expansive drive and was caught at second slip by Liam Dawson off Balcombe.
Gareth Rees was the second to depart, going leg before to Chris Wood, and then Nick James, brought into the side to bolster the middle order for his first game of the season, was neatly caught by wicketkeeper Michael Bates standing up to Hamza Riazuddin.
Before lunch they lost two more wickets. Slow left-armer Danny Briggs struck in his fourth over to have Ben Wright caught at short leg by James Vince and just two overs before the interval, Jim Allenby went lbw to Balcombe playing across the line.
Rain during the lunch interval forced a delay of an hour to proceedings. Will Bragg seemed to enjoy the break, taking two fours off Balcombe's first over of the afternoon session to move to 42.
Another break for rain, however, proved calamitous for the Welsh county as they further collapsed from 87 for five to 95 for nine in the space of only three overs.
Bragg threatened to become Glamorgan's first half-century maker of the season but on 45 he was brilliantly caught one-handed, low down at second slip, by Liam Dawson off Wood.
And 90 for six became 90 for seven five balls later with Moises Henriques falling leg before to Balcombe, who then had Graham Wagg caught at mid-off attempting to pull.
Balcombe completed his five-wicket haul by trapping Dean Cosker leg before.
Skipper Mark Wallace and Huw Waters held on until play was stopped by a third rain break as 41 overs of the day were lost.
Adams fell early in the Hampshire reply but Dawson (18 not out) and Michael Carberry (6no) saw them to the close with no further casualties.
