The Republic of Ireland striker netted on 7.69 seconds, directly after the Hornets kicked off, as he blocked a Craig Cathcart clearance before bearing down on goal and lofting the ball over goalkeeper Ben Foster.
Long's goal at Vicarage Road broke a 19-year record held by Tottenham Hotspur, defender Ledley King, who scored 9.82 seconds after kickoff against Bradford City back in December 2000.
There was even more good news for Long this week as he was handed his Premier League award for having reached 50 goals in the top flight, the goal coming earlier this month prior to his record-breaking strike against the Hornets.
He hit the milestone mark when he netted in the 3-1 home loss to Liverpool earlier this month, becoming only the fourth player from the Republic of Ireland to do so, following in the footsteps of Niall Quinn, Robbie Keane and Damien Duff (Southampton website).
Here is how some of the Saints fans reacted on Twitter to Long's latest accolade:

If Long got three goals in three I was gonna get his shirt number put into a sleeve tattoo I'm having done.... I might just do it anyway! What a turnaround and I love how the guy just does not let up on the pitch.— Kev Farren (@Kev_Fazza) April 24, 2019
Can he make it 51 52 and 53 on Saturday please and I get a tattoo of him on my leg— richard geddes (@richardgeddes83) April 24, 2019
Think we need to give Shane an award every week.— Val (@vep60) April 24, 2019
Well done— Dan Rush (@DanRush17) April 24, 2019
Southampton are two places and six points above the Premier League relegation zone with three games remaining, and up next for them is a south coast derby against Bournemouth at St Mary's Stadium on Saturday afternoon.
