Hampshire began life back in LV= County Championship Division Two with a defeat, but not before putting up a spirited run-chase on a dramatic final day against Gloucestershire at the Ageas Bowl.
All three results were still possible when the players took to the field on day four and it remained that way when Gloucestershire were bowled out for 174 in the morning session - leaving Hampshire 290 required for victory.
A speedy win for the visitors looked a certainty when Hants crashed to 72-6, only for youngsters Matthew Bates and Chris Wood to reignite hopes of victory with a 118-run partnership for the seventh wicket.
But, when Wood fell for 65 and Bates followed him back to the pavilion for a gutsy 87, the home side fell 33 runs short.
Will Gidman, who made 29 runs earlier in the day, claimed four wickets to add to the five he took in the first-innings to finish with match figures of 9-114.
Gloucestershire, who were thrashed inside three days in their season-opener at Essex, leave Southampton with 22 points while pre-season title favourites Hampshire accrued only three.
Will Gidman took five wickets to put Gloucestershire in a strong position heading into the final day of their LV= County Championship Division Two clash with Hampshire at the Ageas Bowl.
All-rounder Gidman, who achieved the rare feat of scoring 1,000 runs and claiming 50 wickets in 2011, recorded figures of 5-48 as Hampshire were bowled out for 199 on day three.
That gave Gloucestershire a first-innings lead of 115, and the visitors increased their advantage to 244 by reaching the close on 129-5.
There was no play due to rain before lunch at Southampton, but when play resumed Hampshire were only able to add 17 runs to their first-innings as Gidman polished off the tail.
Gloucestershire stuttered to 71-5 in their second knock as medium-pace bowler Hanza Riazuddin claimed three quick wickets.
However an unbroken stand worth 58 between Ian Cockbain (27 not out) and Will Gidman (25no) keeps the visitors in a strong position heading into the final day.
Hampshire seamer David Balcombe produced a stellar performance on day two at Southampton but it was Gloucestershire who finished in a strong position.
Balcombe claimed career-best figures of 8-71 as Gloucestershire went from an overnight 195-4 to 314 all out.
Opening batsman Chris Dent, on 59 at the start of the day, advanced to his second first-class century from 231 balls before being eighth out for 114.
He was one of only two wickets not claimed by Balcombe, whose haul included five of wicketkeeper Michael Bates' six catches.
Only Simon Katich, with 74, resisted for long as Hampshire slumped to 182-7 in reply by stumps, Gloucestershire's new-ball pair Will Gidman (3-43) and Ian Saxelby (3-37) each claiming three wickets.
Half-centuries from Chris Dent and Ian Cockbain rescued Gloucestershire from a tight spot on a rain-affected opening day of their County Championship match with Hampshire in Southampton.
Asked to bat in overcast conditions, Gloucestershire were struggling at 87-4 in the afternoon session after Hampshire seamer David Balcombe (3-38) made inroads with the new ball.
But opening batsman Dent combined with Cockbain in an unbroken 108-run stand for the fifth wicket to guide the visitors to 195-4 by the close, which came after just 60 overs due to a combination of bad light and more rain.
Dent's 59 not out spanned 171 balls and featured eight fours in a minute short of four hours, while Cockbain found the rope nine times on the way to 52 not out.
