Urawa Reds exorcised their Emperor's Cup ghosts with a fortuitous 1-0 extra-time win against second-division strugglers Ehime FC on Monday to book their spot in the fifth round.

Ehime wrecked Urawa's chances of a domestic and continental treble with a stunning 2-0 win in the fourth round last year just days before Reds imploded to hand Kashima Antlers the J. League title on the final day of the season.

Ehime held firm in regulation time at Komaba Stadium, but Robson Ponte ensured there would be no repeat of its giant-killing act when he struck the decider from the penalty spot five minutes into the first extra period.
