Jake Lehmann has converted a fifty into three figures at the sixth attempt as Hampshire avoided defeat at home in the County Championship for the first time in 10 months.
Champions and table-toppers Nottinghamshire had hoped to rip through the hosts on the final day to secure victory, but despite Fergus O'Neill taking match figures of 8-86 they found his fellow Australian blocking their path as they finished on 6-207 with a lead of 192.
Lehmann, who qualifies as a domestic player, had scored five half-centuries – all in succession – earlier in the season before batting out the day for a 205-ball 102 not out.
The draw means both sides take 11 points from the match, enough to keep Nottinghamshire top, but not enough for Hampshire to escape the bottom.
Lehmann, the son of Australia great and Northamptonshire head coach Darren, has been a rare bright spark in Hampshire's underperforming batting line-up.
His unconventional stance, almost standing completely front on when the ball is delivered, looks susceptible to lbws and getting the ball onto the offside, but a mixture of quick hands and repositioned feet means he is difficult to dismiss.
He stuttered his way through the late 80s and early 90s before reaching his century – the 17th of his first-class career – with a flick off his hips for four.
There was good news too for Lehmann senior as Northants gained a two-wicket victory over Cameron Bancroft's Division Two bottom club Gloucestershire.
Nathan McSweeney made a valuable 46 as Northants chased down a victory target of 249.
Back in Division One, Yorkshire thrashed Surrey by an innings and 127 runs with Harry Brook taking 3-11. The weather denied Somerset a victory shot against Sussex, for whom Daniel Hughes made 21 after his first-innings century, and Beau Webster was not required at the crease as Warwickshire batted out for a draw with Glamorgan.
Ben Stokes made 45 for Durham in his first innings of the season, which has been delayed due to facial injuries received in the nets post-Ashes.
The England skipper, who took 1-96 in 19 overs when Kent batted, was dropped twice in his two-hour knock. Durham went on to avoid the follow on and force a draw after a 158-run tenth-wicket partnership.
