He finally caught up with Cosmo Laputa, who was running alone in the lead, 150 meters before the finish line.
Rose Kingdom and Beat Black chased him but could not catch him.
It was his first G1 win.
It was also the first G1 victory for the stallion Bago.
This race was also the last G1 victory for Yuzo Tanimizu of Country Bokujo. - He did not have good results after that.
He turned to hurdle racing horse in 2013. - He ran in the Hurdle Maiden over 3yo on July 13, 2013 and won.
This was the first time a winner of a classic race had raced in a hurdle or steeplechase since Dai Koter, who won the Kikuka Sho in 1965.
(Dai Koter is also a well-known rival of Keystone.)
He ran in four more steeplechase races but failed to win.
Dai Koter became a successful stallion, but he did not even become a stallion.
He has been cared for as a riding horse since his retirement.
