The American pulled off several wonder saves to keep Villa in the game.
He told Villa's website: "It was a massive result for us and as a goalkeeper you try to play your part and make some saves. Fortunately I was able to do that.
"As a goalkeeper you are going to be called upon, whether it's the first minute or the ninetieth minute. You have to be ready.
"I was able to keep them out in the first half but the effort in the second half from the guys was massive.
"It's one of those where you continue to try and help the guys in front of you stay in the game.
"That's part of the job of a goalkeeper. You have to give your team the chance to be successful and get a result."
