Heaven Rocks A was a well known headcase down under often needing outrider assistance and was put on the "unruly for mobile starts draw list" at one point. He also had some lameness issues there.
His last start here was at the Red Mile in October 2018 where he was leading in a 52.1 half, 119.1 3/4 before finishing up the track in a race won by McWicked. Probably hurt himself as he hasn't been seen since
