Gaston was between the sticks for Ton the last time they lost at home last March.
The stopper told the Tele he remembers the defeat to Raith Rovers — as he was nutmegged by goalscorer James Craigen for the winner.
He told the Tele: “I actually made a mistake for the goal.
“I don’t think many teams imagine they can go a full year undefeated — and we’re still not really putting too much focus on it.
“We actually haven’t spoken much about the run, today is simply another big game for us to try and go out there and pick up three points.
"A draw would keep us unbeaten for the year as well but we’re not looking for a draw, we’re looking to win the match.
“But if we can manage to remain unbeaten after today, it’s a nice thing to be able to mention.”
Gaston insists Morton’s ambitions at the beginning of this campaign were simply to improve on last season’s fifth placed finish in the league. And he is delighted to be able to say that it’s ‘mission accomplished’ on that front.
He said: “Last season we had a good season, we did really well to finish fifth, but this year we’ve done great things to improve on that.
"At the start of the season we would’ve been happy on any improvement, but with the results and how well we’ve been playing in terms of our football, it’s been a big step forward in every respect.
“At this stage in the season usually there are teams out of the running for things and sometimes there’s little to play for. This year, everyone seems to have something so every three points are massive.”
Parklea and Cappielow have been buzzing this week after last Saturday’s victory over Falkirk, and the 29-year-old says that has been the case for the majority of this season.
And he hopes to be able to say the same thing next week after the dust has settled on today’s home clash.
He concluded: “This week the atmosphere has been superb. It’s not often this season though that we’ve come in to training after a defeat.
“We’ve had that all season, and we hopefully can take that positivity into the game today.”
