The match between Hampshire and Somerset petered out into a run-filled draw on the final day at the Rose Bowl.
Jos Buttler and Damien Wright (51) shared a seventh-wicket stand of 103 before Somerset, on 441-6 at the start of the final day, were eventually all out for 524 to claim a first-innings lead of 12.
Buttler, 105 overnight, was ninth out for a career-best 144, featuring 16 fours and a six, while Sri Lankan left-arm spinner Rangana Herath took the final three wickets of the innings to finish with 4-98.
Hampshire suffered a brief wobble at the start of their second innings, left-arm seamer Charl Willoughby (2-7) accounting for openers Jimmy Adams (0) and Michael Carberry (2) to leave them on 2-2.
But third-wicket duo Liam Dawson (13no) and Neil McKenzie (22no) steadied the ship, guiding Hampshire to 37-2 when a draw was agreed.
Both teams have yet to win a four-day game this season and remain in the lower reaches of the Division One.
Centuries from James Hildreth and Jos Buttler ensured Somerset reached stumps on the third day at 441-6 in reply to Hampshire's first-innings score of 512 at the Rose Bowl.
Resuming on 104-2, Nick Compton and Hildreth forged a fourth-wicket stand of 90 either side of lunch after the early loss of Zander de Bruyn (21).
Compton was run out on 49 but Hildreth found another willing ally in rookie wicketkeeper Buttler, only in the team because Craig Kieswetter is away with England at the ICC World Twenty20.
The fifth-wicket duo added 105 as Hildreth went to his first century of the season, and 13th of his first-class career, from 153 balls just prior to tea.
He was out for 106 early in the evening session, one of three victims on the day for Hampshire seamer David Griffiths (4-94).
But there was no stopping Buttler, who went to his maiden hundred from 185 balls shortly before the close, when he was unbeaten on 105 in the company of Damien Wright (17no).
Somerset still trail by 71 and, barring a contrived run chase, a draw looks the likely outcome on the final day.
Sean Ervine plundered a career-best 237 not out to put Hampshire in a dominant position after the second day against Somerset at the Rose Bowl.
Number seven Ervine, on 75 overnight, shared stands worth 130 with James Tomlinson (42) and 53 with David Griffiths (5) for the ninth and 10th wickets respectively as the hosts, who resumed on 281-7, piled up 512 in their first innings.
That represented a remarkable turnaround from Hampshire, who had been reduced to 123-5 after opting to bat first on the first day.
Ervine, the Harare-born left-hander, struck 29 fours and five sixes during his 333-ball innings and was left stranded when last man Griffiths was dismissed by occasional off-spinner Nick Compton (1-1) on the stroke of tea.
In reply, Somerset lost openers Marcus Trescothick (41) and Arul Suppiah (27) to reach the close on 104-2, still 408 behind.
Nic Pothas and Sean Ervine rescued Hampshire from early trouble to finish the first day against Somerset at the Rose Bowl on 281-7 in their first innings.
Somerset seamer Charl Willoughby (3-39) struck twice with the new ball and added a third victim, James Vince (26), after lunch as the home side were reduced to 123-5 after opting to bat first.
But Pothas hit 87, including 12 fours and three sixes, and Ervine plundered 75 not out from 131 balls as Hampshire fought back from mid-afternoon onwards.
The sixth-wicket pair added 158 as Somerset skipper Marcus Trescothick rotated his seven bowling options without success.
Pothas did finally depart 13 short of a century as seamer Ben Phillips (2-38) claimed two wickets in the final three overs of the day.
