Derek McInnes lauded his tired and tenacious Aberdeen team after they made a winning return to Scottish Premiership duty at St Johnstone.

In their first fixture in 19 days - after having three games postponed for Covid-19 breaches by eight players - the makeshift visitors snatched victory with Ryan Hedges' late strike.

St Johnstone were the slicker side but failed to capitalise on their rivals' rustiness in this rearranged game.

"We will get better," said McInnes.

"But what we can't improve is that commitment. A few boys hadn't played for a while and you could see we looked a tired team.

"It was all about getting that first win, no matter how you get it. We showed moments of quality at the right time."

Substitute Hedges' strike took a nick off Liam Gordon to secure Aberdeen's first victory of the season and lift them to eighth, one place below St Johnstone.

Of the 'Aberdeen eight', four were available, yet only Jonny Hayes started. Unsurprisingly, with four strikers sidelined, there was a disjointed look to McInnes' line-up.

The nervousness permeated the team, with even basic passes frequently going astray.

St Johnstone, though, were badly let down by a lack of end product. The hosts mustered just one shot on target all game, a Danny McNamara drive tipped over by Joe Lewis.

Callum Hendry rattled the post in the first half, but was correctly penalised for handball, before blazing wide after being gifted possession by Tommie Hoban in the second period.

Aberdeen coped comfortably at the back, where Ross McCrorie was making his debut following a move from Rangers.

The visitors almost took a shock lead shortly before half-time, with Funso Ojo's acrobatic volley from a Hayes cross dropping just wide.

And they improved after McInnes made a double substitution at the break. Hoban glanced a header narrowly off target before Hedges - who only came on three minutes earlier - cut inside from the right flank to deceive goalkeeper Elliot Parish with a deflected finish.

Man of the match - Ryan Hedges

What did we learn?

Aberdeen relish trips to Perth. It's now seven games unbeaten at McDiarmid Park for the Pittodrie side and this win - while far from pretty - was the best of the lot. Their sheer dogged determination is to be admired. They were well off the pace for long spells, but defended stoutly and weren't content to settle for a point.

St Johnstone have started the campaign brightly, but their lack of attacking thrust in this defeat is a major concern. Aberdeen's lack of action left them there for the taking, yet the hosts were dismal in the final third. Davidson must demand much better.

What did they say?

St Johnstone manager Callum Davidson: "We defended really well, we snapped into tackles, put Aberdeen under pressure. It's the final third where we lacked that little bit of quality.

"For me it had 0-0 written all over that game. It was a poor goal, we could stop it at the source better, and then we didn't move the ball well enough after that."

Aberdeen manager Derek McInnes: "In light of everything, the stop-start nature of our campaign, just getting up and running, it was all about getting that first win no matter how you get it.

"It's a difficult place to come, they set up to frustrate and counter-attack. That said, we know we can do better and we'll do better as we go along."

What's next?

Both sides don't play until Sunday, with Aberdeen hosting Livingston at 15:00 and St Johnstone staying in Perth to take on undefeated Hibernian at 16:30.
