Partick Thistle co-manager Mark Wilson: "I'm pleased for the club, 1,800 fans came down here and it would've been easy for them not to come after losing the first leg.
"The game plan worked, I knew we'd get another chance and thankfully it fell to Brian."
Partick Thistle interim co-manager/player: "That takes real character. We're down to the bare bones, we've not really got the squad to pick from and we relied on a 17-year-old kid (Jamie Low) to come on and play wing-back.
"The kid has come in tonight, he's not put a foot wrong. He was absolutely different class and I'm so happy for him."
Partick Thistle player Jamie Low: "I only found out before the game when he named the team. We spoke briefly yesterday in training and he said it's possible I could get game time. I never knew it was a guarantee.
"He owes me £100. In the warm-up, we actually spoke about that exact corner."
Ayr United manager Scott Brown: "You're not going to win a game of football if you've got 11 shots and you don't hit the target. It's disappointing mentality-wise.
"Throughout the game, we were fine. It comes down to mentality, it just comes down to the willingness, desire to win the game and we weren't good enough in the final third.
"That's on me. I've got to have a long hard think about things now and see where I go from here. I've got to take a little bit of time to think about the game and the situation because watching that, it's not really my team and that was the disappointing factor. We'll just see where we go together."
