RAIN and Jimmy Adams put a dampener on an opening day that promised plenty for Gloucestershire in LV= County Championship Division Two.
Left to rue his decision to bat first beneath leaden Bristol skies, Hampshire captain Adams showed redoubtable resolve to claw his way to a half-century after teenager Craig Miles had swung a wrecking ball through his middle order.
The County were also left fretting over an ankle injury picked up by Will Gidman, another cloud that Michael Klinger could have done with dodging as he manages increasingly threadbare resources.
Still precariously placed on 165 for eight when wet weather forced a curtailment of the action after 60 overs, the visitors had opened the batting with Adams and Championship debutant Michael Roberts following Michael Carberry's selection for the England Lions.
And frustration at a slow scoring rate seemed to get the better of 24-year-old Roberts in the ninth over, as he nibbled at a seaming delivery from Gidman and was caught behind by Cameron Herring for nine.
Gidman struck again in his next over when Liam Dawson (0) was brilliantly caught by County captain Klinger at third slip.
The fresh-faced Miles was brought into the attack as second change, and he cleaned up Australian George Bailey for 13 with one that kept low before pinning another potential danger man James Vince (9) leg before.
And the 18-year-old seamer was celebrating again when veteran Sean Ervine (4) mistimed a drive to Dan Housego at point.
A dream morning for Klinger was completed in the final over before lunch, as Adam Wheater (8) attempted an extravagant pull to off-spinner Jack Taylor and was adjudged leg before.
It left Hampshire in disarray on 69 for six at the start of the second session, and it was imperative that the County now showed the maturity demanded by Klinger in order to ram home their advantage.
David Payne had bowled with admirable discipline without reward in the morning session, but that changed when Chris Wood (7) chipped into the hands of Benny Howell at mid-on.
And it was 97 for eight when David Balcombe (12) made a mess of an ill-advised sweep and was rapped on the pads for Taylor's second scalp.
Adams at last found genuine support in the shape of England one-day cap Danny Briggs, a slow left -armer from the Isle of Wight with the heart of a lion and no shortage of talent as a wielder of willow.
Their stand had reached 68 when rain forced an early tea, and with no let-up in conditions play was abandoned with a session unplayed.
