Republic of Ireland international Michael Obafemi scored his first senior goal as Southampton took a 3-1 lead away to Huddersfield.
The teenager, who made his international debut under Martin O'Neill against Denmark last month, was a 65th minute substitute, replacing Danny In gs up front at the John Smith Stadium.
Six minutes later he had notched the first senior goal of his career, as he slotted home after great work by Nathan Redmond.
His team-mate worked his way in the touchline ont he left hand side of the penalty area and cut the ball back to Obafemi, who controlled the ball before sweeping it across goal and into the right side netting.
18y 169d - At 18 years and 169 days, Southampton striker Michael Obafemi has become the youngest player from the Republic of Ireland to score a Premier League goal. Talented. #HUDSOU— OptaJoe (@OptaJoe) December 22, 2018
With Obafemi, Charlie Austin, Redmond, Ireland team-mate Shane Long, Manolo Gabbiadini and Ings battling for spots up front under new boss Ralph Hasenhuttl, it was a well timed strike from the 18 year old.
It was only his fifth Premier League appearance of the season and his sixth in total, having made his top flight debut last January at home to Spurs.
The impressive Redmond opened the scoring in the 15th minute and Ings scored his eighth of the season from the penalty spot three minutes before half-time.
Philip Billing pulled one back for Huddersfield in the 58th minute - just the fourth goal the Terriers have scored at home in the league this season - but Obafemi condemned them to a fifth straight defeat.
The Saints had not won a game in any competition since 1 September before last week's win over Arsenal, but they now have two on the trot after Mark Hughes was replaced by Austrian Hasenhuttl.

Watford striker Troy Deeney gleefully helped halt West Ham's winning run and lifted the Hornets towards the top six.
The skipper slammed home a first-half penalty and Gerard Deulofeu added a late second to sink West Ham 2-0 and scupper their bid to win five matches on the spin.
Deeney, relishing his role as pantomime villain at the London Stadium, celebrated his successful spot-kick by punching the corner flag out of the ground and goading the home supporters.
The 30-year-old certainly seems to relish playing against West Ham. Two seasons ago he accused the Hammers of "trying to mug us off" with their showboating after he inspired Watford to come from two goals down and win 4-2.
Fortunately only one home supporter reacted to his 'exuberant' celebration, and the paper cup that was thrown towards the striker fell a long way short.
West Ham, looking to climb into the top six themselves, had chances to equalise, but Michail Antonio twice hit the woodwork before Deulofeu finished them off three minutes from time.
David Brooks claimed both goals as Bournemouth returned to winning ways by beating 10-man Brighton.
Wales international Brooks fired in from outside the box for the first-half opener, before heading home a second 13 minutes from time.
Chris Hughton's Albion were a man down for the final 17 minutes after captain Lewis Dunk was dismissed for two bookable offences.
Defender Dunk, whose cautions came in the space of 11 minutes, perhaps had reason to feel aggrieved as his first yellow card was shown following a foul on Brooks which appeared to be committed by Yves Bissouma.
The victory was just Bournemouth's second from eight Premier League fixtures and inflicted a third successive loss on the visitors.
Meanwhile comedy fan Rafael Benitez had the smile wiped from his face as Newcastle were held to a drab goalless Premier League draw by bottom-of-the-table Fulham.
The Magpies did not manage a single shot on target to leave the Spaniard, who admitted in the run-up to the game that he loves English sitcoms, stony-faced ahead of an intensely difficult Boxing Day trip to face leaders Liverpool.
Opposite number Claudio Ranieri may have been marginally happier after watching his side keep a first top-flight clean sheet, but they too failed to trouble Magpies goalkeeper Martin Dubravka to any great extent in an awful game in front of a crowd of 51,237 at St James' Park.
