St. Mirren vs Partick Thistle Prediction 25 May 2026

St. Mirren and Partick Thistle meet on May 25 in a crucial Premiership qualification clash, with both sides aiming to take a major step toward securing top-flight football next season.

St. Mirren enter the match struggling for consistency. The hosts have managed just one victory in their last six games, suffering four defeats during that stretch while continuing to battle defensive issues. Steve Robinson’s side have conceded 13 goals in those matches and often looked vulnerable at the back, while their attack has failed to provide enough support with only five goals scored. Their recent 1-1 draw against Dundee United at least showed some fighting spirit, but it also highlighted the same recurring problem — converting chances into victories.

There is still some encouragement for the Saints ahead of this encounter, particularly their recent head-to-head success against Partick Thistle. Back in March, St. Mirren secured a 2-1 victory over the Jags, continuing a strong run in this fixture. However, confidence around the home side remains fragile given their current form and inability to keep clean sheets consistently.

Partick Thistle arrive in far steadier condition. Ian McCall’s men are unbeaten in six consecutive matches, although four of those ended level. Their defensive organization has been the foundation of this run, with only five goals conceded during that period. While their attack has not always been convincing, Thistle have shown discipline and resilience, qualities that become especially valuable in tense playoff matches.

The visitors will also feel they are overdue a stronger performance against St. Mirren after losing their previous three meetings. If Partick can maintain their defensive solidity and show slightly more composure in front of goal, they have every chance of extending their unbeaten streak.

Given St. Mirren’s poor recent form and defensive struggles, this looks likely to be a tight and low-scoring contest where avoiding defeat may already represent a positive result for the visitors.

Prediction: Partick Thistle not to lose (X2) — 1.38
