Opener Chris Nash hit 162 to help Sussex secure a draw on the final day against title-chasing Nottinghamshire at Trent Bridge.
The 29-year-old carried on from his overnight score of 79 to hit a century that helped the visitors erase a 349-run deficit for the loss of just two wickets.
Although he wasn't quite there when his team moved in front, Nash managed to bat for over six hours, hitting a six and 22 fours from the 306 deliveries he faced.
Ed Joyce played his part in the rearguard effort, battling his way to 98 before Samit Patel finally ended the opening partnership of 216 by getting the Irishman caught by Michael Lumb.
However Luke Wells (59) made his second half-century of the match to help add 98 for the second wicket in conjunction with Nash, who was eventually dismissed by Andy Carter with the score on 314.
Murray Goodwin weighed in with 31 and although he became the fifth wicket to fall when he was bowled by Patel, Nottinghamshire already knew they had run out of time.
Ed Joyce and Chris Nash shared an unbroken stand of 146 to raise Sussex's hopes of escaping with a draw against Nottinghamshire.
Coming out to bat a second time facing a huge deficit after the hosts had declared their first innings on 520-4, Sussex's opening duo managed to get through 51 overs unscathed, though their cause was helped by rain.
Ireland international Joyce reached stumps unbeaten on 63 while Nash had 79 not out to his name, though the visitors still trail at Trent Bridge by 203.
Nottinghamshire, who trail Division One leaders Warwickshire by one point, will have cursed the grey clouds that twice halted play, but they never seriously
troubled either batsman.
Earlier James Taylor and Adam Voges (44 not out) scored 77 in just over an hour, taking their stand to 148, before Nottinghamshire captain Chris Read decided to end the misery of the Sussex bowlers.
Taylor celebrated his England call-up for the second Test against South Africa at Headingley with an unbeaten 163 that included a six and 21 fours.
Centuries from Michael Lumb and James Taylor have put Nottinghamshire in complete charge at the halfway stage against Sussex at Trent Bridge.
Resuming on 88-1 in reply to the visitors' 171, Nottinghamshire recovered from the early loss of Riki Wessels to reach the close on 443-4, meaning they hold a massive lead of 272 over their Division One rivals.
Lumb had begun in the morning on 28 and went on to make his third ton of the LV= County Championship season and the 15th of his first-class career.
The left-hander shared a 90-run alliance with Samit Patel (43) and then combined with Taylor to put on a stand worth 188 for the fourth wicket.
Eventually Steve Magoffin broke the partnership by bowling Lumb for 171, the former Hampshire batsman having hit 27 fours and two sixes in his 273-ball knock.
However Taylor remained unbeaten through to stumps, a six and 15 fours taking him to 106 not out. Adam Voges will resume again on day three with 32 to his name, with Nottinghamshire looking to pile on the agony for Sussex.
Andy Carter took 3-41 as Sussex were dismissed for 171 on day one of their Division One clash with Nottinghamshire at Trent Bridge.

Luke Wells launched a counter-attack as he shared a third-wicket stand of 48 with Murray Goodwin before Phillips struck again to remove the latter for 19.
Michael Yardy was run out by a smart piece of work from Riki Wessels and when Adams' second wicket accounted for Luke Wright, Sussex were struggling to reach three figures at 89-5.
Wells (54) finally found some solid support from Ben Brown - his 37 helping Sussex limp towards 171 as Carter mopped up the tail with some clinical bowling.
Amjad Khan trapped Alex Hales (8) in front early on in the Nottinghamshire reply, but Wessels and Michael Lumb guided the hosts to 88-1 before stumps.
