Cassidy: Losing victory to engine blow-up “heartbreaking”

From pole, reigning champion Cassidy was pulling away from second-placed Toshiki Oyu early on in the 30-lap race, before his Toyota engine let go at the start of the ninth lap.
Oyu went on to take his first Super Formula win ahead of Nirei Fukuzumi, as Saturday race winner Naoki Yamamoto dropped out with suspected gearbox trouble.
