The 27-year old American goalkeeperâ€™s deal at Villa Park had expired this summer and it appeared as though he would depart the club but he has taken a U-turn and decided to put pen to a three-year deal delighting new manager Paul Lambert.
"I've watched Brad and some of his games when he was in the team last year and he was excellent," the Villa boss told the clubâ€™s official website.
"I know he's always had that stigma of being the number two behind some really good goalkeepers here.
"But when you come back at the start of the season nobody knows what's going to happen and it depends on whoever does well.
"Brad played very well the time he was in and maybe he found himself a bit unlucky to be back out.â€ť
