Ace of Diamond

The Two Batteries (1x7)

Air date: Nov 17, 2013

The game concludes, and Furuya and Masuko are promoted to varsity while Eijun and Haruichi are promoted to JV. Along with the promotion comes additional pitchers training for Furuya and Eijun. However their training can only be done with the partners that Coach Katoka assigns them. Furuya is assigned to work with Miyuki while Sawamura is assigned to work with Chris. However instead of catching Eijun's pitch, Chris continually gives him additional work that isn't pitching, making Eijun think the coach has gotten the last laugh and that he won't succeed at Seidou.
