Derek McInnes was thrilled after his Kilmarnock side edged closer to securing European football with a confident victory over St Johnstone.

Killie deservedly took the lead midway through the first half when Joe Wright turned home Liam Polworth’s pin-point delivery – and the visitors were denied on multiple occasions to extend their advantage by the heroics of Dimitar Mitov.

The game was settled with nine minutes remaining after Marley Watkins tapped home his 13th goal of the season.

Kilmarnock have extended their advantage in fourth place to eight points, with just five games remaining.

“I thought first half we were very good,” McInnes said.

“Coming away from home, we tried to impose ourselves. We spoke throughout the week about the importance of matching their motivation.

“We knew we were up against a team with so much riding on the game, we had to match that and a bit more.

“I was bemoaning the fact we didn’t get that second goal, which we maybe merited for our first half dominance as an away team – to have that control was really pleasing.

“We never got started in first 20 minutes of the second half but thankfully we got the second.

“It’s not easy winning games in this league, especially away from home – we did a lot right and credit to our players.”

Despite moving one step closer to returning to Europe for the first time since 2019, the Rugby Park boss insists there is still work to do.

Kilmarnock have lost just one of their 11 Premiership encounters since returning from the winter break in January.

He added: “There’s still work to be done and hopefully a few more special days to have.”

Craig Levein felt his team failed to hit the heights of recent performance during a lacklustre showing.

Saints were unable to build on their excellent victory against Hibernian at Easter Road as they slumped to defeat at McDiarmid Park.

St Johnstone remain 10th in the table and look set for a battle to avoid the play-off position in their post-split fixtures.

“The rollercoaster is back in operation. It was a hell of a frustrating afternoon,” Levein said.

“After the last two games I’ve been talking fairly confidently about continuing at that level.

“We didn’t play with the confidence I thought we should’ve done because of our previous performances.

“Individually we didn’t have that many players who played anywhere near their best.

“Kilmarnock didn’t batter us by any stretch of the imagination and we had some good chances.”
