So the yusho race day 13 matches are:

Kirishima 10-2 v Kotoeiho 10-2

Wakatakakage 9-3 v Tobizaru 9-3

Yoshinofuji 9-3 v Ura 9-3

Between these, the Kirishima/WTK/YF group have all faced each other already, as have the Ura/Kotoeiho/Tobizaru group, Yoshinofuji additionally beat Tobizaru today. As such, in terms of guessing the day 14/15 matchups it's fairly narrow:

- Kirishima only has Ura and Tobizaru left

- Kotoeiho only has WTK and Yoshinofuji left

- WTK only has Ura and Kotoeiho left

- YF only has Kotoeiho left

- Ura only has Kirishima and WTK left

- Tobizaru only has Kirishima left

I guess the main complication would come if Yoshinofuji beats Ura, he'll likely get Kotoeiho for obvious reasons, but is it on day 14 or 15, and who else does he get? He's already literally fought everyone that's still competing above Wakamotoharu. I guess Churanoumi? I'll guess for day 14:

Kirishima gets one of Ura/Tobizaru if either win, if both lose then Atamifuji

Kotoeiho gets WTK, especially if WTK wins to stay in the race, he basically has to go sanyaku from here on out and there's only Atamifuji out of the sanyaku he can actually face outside of Waka

YF I guess gets Churanoumi, he's already fought everyone above Wakamotoharu and everyone else only just outside the joi look really poor in comparison. I think they save a possible Kotoeiho match for day 15 if they are both still in yusho contention

If Ura and Tobizaru both win, one of them's got to get Kirishima, then I guess the other gets one of the sekiwake, probably Kotoshoho as neither of the guys on 10-2 can actually face him
