Partick Thistle continued their terrific start to this year’s Championship campaign as they came from behind to defeat Ayr United 2-1 at Firhill.

Ethan Walker put Scott Brown’s side in front in added time of the first half, before a five minute double after the interval from Tsoanelo Letsosa and Ben Stanway gave Mark Wilson one over his former teammate.

The result moves the Jags behind leaders St. Johnstone only on goal difference, with the Perth side inflicting Thistle’s only league league defeat this season on the opening day.

It is the first time Ayr have tasted defeat since Thistle dumped them out the Premier Sports Cup in August.

The away side were under pressure for large parts of the first half, but Thistle failed to make their advantage count. Jamie Murphy sent Walker through, and the right winger made converted The Honest Men’s only attempt on target of the half in first half injury time.

Whatever Mark Wilson said to his players certainly had a lasting impact. One minute into the second period, Logan Chalmers whipped a cross in from the left flank, and Letsosa turned the ball home to bring the scores level.

Then on the 50th minute, Stanway pickpocketed Kyle Ure inside the Ayr penalty box, and his finish sailed to the top right corner with the aid of a deflection to complete the five minute salvo.

Ayr’s goalscorer Walker picked up his second caution of the match with 18 minutes to play, making Thistle’s job of protecting their slender advantage all the easier.

Partick Thistle are now level on points with St. Johnstone, and travel to another one of Wilson’s former teammates in Barry Robson this Saturday to take on Raith Rovers, who have lost their last three games.

Ayr are back in Glasgow on Saturday to face Queen’s Park, hoping to keep 5th place Dunfermline from leapfrogging them into the playoffs before facing them in the Friday night fixture on Halloween.
