He was a 4/6 favourite when an A Block winner market was first published by Kambi in late-June.
As you can see below, the eventual winner closed as a 17/20 joint-favourite alongside today's opponent. However, the latter adjustments that were made to the market were in his favour. His late descent began after rising to 6/4 in late-July.
I checked in on the B Block winner at 9AM BST this morning, but the odds were changed after that.
As it stands, Tetsuya Naito is a 4/6 favourite. He's followed by his opponent for tomorrow - Jay White.
White's price is now down to 7/5 after moving there from 7/4 sometime after 9AM BST today. The two remaining potential winners are Jon Moxley (rose from 7/1 to 8/1 overnight) and Hirooki Goto (went from 33/20 to 7/4 before 9AM and is now up to 9/4).
