Louis Longridge refused to give up on Dunfermline’s play-off aspirations despite the Pars surrendering a two-goal lead as the points were shared at Firhill.
The 27-year-old was outstanding for the visitors, setting up both their first-half goals before Scott McDonald inspired Thistle’s recovery.
The result leaves Dunfermline six points behind Ayr United in the race for the final play-off position but, with five games remaining, Longridge believes anything is possible.
He said: “We can’t stop believing because in this league everyone can beat anyone.
“We can still get to the play-offs and that is our goal, but it makes it a bit more difficult after that result.
“You can’t really think too far ahead but if you beat the teams above you then you give yourself an excellent chance.
“We’ve got a tough game on Tuesday against Ross County but we need to go to the Highlands and try and get a positive result.
“I believe we can get something from the game and there is definitely more added pressure for them because they’re fighting for a league title.”
The Pars were dominant during an impressive first half hour where they raced to a two-goal lead against their lethargic hosts.
Longridge provided the opener after pouncing on a slack McDonald pass before galloping down the left and cutting the ball back to Tom Beadling.
The Australian midfielder showed great composure to dummy two defenders before slamming low past Connor Hazard on 10 minutes.
Man-of-the-match Longridge grabbed his second assist on 24 minutes when his perfect left-footed corner was flicked beyond Hazard by Aberdeen loanee Bruce Anderson.
Ryan Blair had no option but to divert McDonald’s cross into his own net on 31 minutes but Longridge was delighted to be playing well after a poor performance against Ayr United.
“I enjoyed it today because I really didn’t last Friday night. I was disappointed with my performance but happily I was able to contribute today, although it was disappointing not to get the three points,” Longridge concluded.
Veteran Australian striker McDonald has been a revelation, scoring five goals in nine games since signing for the Jags in January.
Longridge described him as a “clinical, natural goalscorer” and he equalised on 78 minutes with a brilliant half-volley that flew past Ryan Scully.
McDonald is delighted to be back playing, saying: “I’m really enjoying being back out there. You can probably see that because I’m not even moaning as much as I used to.
“I just want to get the club up the table. We felt we had them on the ropes so we are disappointed not to get all three points.”
The point moves Partick one point ahead of Falkirk and Alloa after the Wasps secured a 2-1 win over the Bairns at the Indodrill Stadium.
Dario Zanatta smashed in the opener but Ray McKinnon’s visitors hit back just after half-time through Zak Rudden.
But there was more pain in store for Falkirk as Jordan Kirkpatrick handed the points to Jim Goodwin’s side late on.
Queen of the South remain in touching distance of the battle at the bottom after they could only scrape a 1-1 draw with Morton at Palmerston.
Queens sit three points in front of the bottom two.
