Callum Wilson’s smart Bournemouth double denied Southampton the south coast bragging rights, but Saints still sealed their Premier League safety with a 3-3 draw.
Matt Targett’s header looked to have sent Saints storming to a 3-2 derby win to cement their top-flight status in style, only for Wilson to spoil the party late on.
Cherries striker Wilson impressed in front of England boss Gareth Southgate, pushing his league goals tally to 14 – with nine assists thrown in too.
Shane Long’s fourth goal in five league games handed Saints the perfect start, only for Dan Gosling and Callum Wilson to turn the tide for Bournemouth.
Targett’s maiden top-flight goal was also the 1,000th Premier League finish of the season – but boasts far greater significance for Saints as the goal that seals their safety.
Cardiff’s 1-0 loss at Fulham leaves Saints seven points clear of the Bluebirds with two games to play.
Hasenhuttl quickly transformed the atmosphere and attitude at St Mary’s however, and now his side can look forward to more productive times.
Gosling coasted through Saints’ centre all to easily though, before drilling Bournemouth’s equaliser.
Saints were clearly aggrieved and vented some frustration when Ward-Prowse fired home from 20 yards.
Hasenhuttl’s steely Saints then wrestled back the lead, Ings unable to chest and turn in the box – but capable of stealing possession again and finding Ward-Prowse.
He laid out an inviting ball to Yann Valery, and the right-back’s whipped cross ushered in left-back Targett to nod home at the far post.
Instead Wilson tapped home his second, and should have wrapped up a hat-trick only to fire at Gunn’s legs when clean through.
