Barry Roche is the first goalkeeper to score against Pompey in their 96-year Football League history.
That was the full extent of the feat achieved by the Morecambe player in Tuesday night’s 1-1 draw.
Roche charged upfield to head home Shaun Miller’s left-wing corner in the fourth minute of time added on at the Globe Arena.
In doing so, he created a unique place in Blues history, albeit for the wrong reasons in the eyes of the Fratton faithful.
For the 33-year-old, it was a first goal in 493 appearances during a career that has taken him to Nottingham Forest, Chesterfield and Morecambe.
No Pompey goalkeeper has ever netted for the club since reaching the Football League in August 1920.
Goal-scoring keepers remain a rarity in this country, however.
Ex-Blues keeper Jimmy Glass did, though, famously keep Carlisle in the Football League with a winner with 10 seconds remaining.
He struck against Plymouth in May 1999 to give the Cumbrians a memorable 2-1 triumph.
Glass spent a three-game loan spell at Fratton Park in the 1994-95 campaign.
Asmir Begovic, then with Stoke, scored against Southampton in November 2013.
His goal was a right-footed clearance from his own penalty area and is recorded as the fastest goal by a keeper at 13 seconds.
Finally, Mart Poom scored a 90th-minute equaliser with a diving header for Sunderland in the Premier League in September 2003.
Ironically it came at Derby County – the club he left to join the Black Cats nine months earlier.
Poom made seven appearances during two Pompey seasons.
