DANNY INGS struck his second goal of the season to give Saints their first win of the league season.
The on-loan Liverpool striker – a pre-match doubts with blisters – scored just after half-time as the curse of the injured Wilfired Zaha struck Palace again.
He was ruled out with a groin injury and Palace were given a frightening look at what life would be like if he ever leaves.
It’s now 707 days since Palace last won a game without him starting as Pierre-Emile Hojbjerg, sent off last weekend, scored on the counter attack in stoppage time to seal the win with his first Premier League goal.
Palace struggled and Wayne Hennessey was easily the busier of the two keepers in a one-sided first half which Southampton dominated.

Palace had no attacking threat even though Jordan Ayew made his first start alongside the out-of-form Christian Benteke, who has scored just three goals since the start of LAST season.
So the visitors, without a Premier League win since May, pushed men forward to try to break the deadlock.
Only Hennessey stood in their way before the interval.
He pulled off flying stops to deny Nathan Redmond and Hojbjerg but reserved his his most impressive save to prevent an own goal from Luka Milivojevic.
Palace captain Milivojevic flung himself at a free kick but his header was arrowing into his own net until Hennessey spectacularly tipped it over.
Woeful Palace did not have a shot on target until first half injury time when Milivojevic hit speculative volley from 40 yards which ex-Eagle Alex McCarthy saved easily.
Ings strucke in the 47th minute after Martin Kelly indecision, and later Austin flopped on the spot following Aaron Wan-Bissaka’s handball.
James McArthur did hit the woodwork for Palace, and McCarthy puled off some great stops late on before Hojbjerg sealed the three points with a composed finish.
