Shikoku's tournament is short (just 7 games in total), and the first round (which is the quarterfinals) are done.
Meitoku Gijyuku (Kochi 2) - which really isn't fair if you ask me - mercy-ruled Jyounan (Tokushima 1) 8-1 in 7 innings.
They'll face off against Kawanoe (Ehime 1), who rallied to beat Sangawa (Kagawa 2). After jumping out to a 3-0 lead in the bottom of the 1st, Sangawa struck back with 5 runs in the next half inning and it seemed like all momentum was lost. But after a run in the 4th, they would retake the lead with a pair in the 5th. An insurance run in the 7th proved to be the difference as Sangawa would get a run in the 9th, but fall short 7-6.
Kagawa Nishi (Kagawa 1) used a 3-run 1st inning to advance against a late-inning charge from Jyoutou (Tokushima 2) 4-2.
And in the surprise of the tournament (which again isn't saying too much, but in this case is really surprising), Kochi (Kochi 1) was out-dueled by Mishima (Ehime 2)! They were not phased after falling behind 2-0 in the top of the 1st, immediately got one of the runs back, took the lead with a pair in the 5th, and for good measure added a run in the 8th!
Realistically, this should be a Meitoku Gijyuku-Kagawa Nishi final, but there's still the semifinals to be had.
