Ace of Diamond: I'd Never Squat!

"I, Chen Yu, would rather die than jump off the dormitory!"

"It's impossible for him to be a catcher. He'll never be able to be one in this lifetime. Miyuki is treacherous and Okumura is stubborn. He can only stay in the starting lineup by playing in the outfield."

"Being a sniper is like being in jail right where you are. My fast legs yearn for the freedom of the outfield."

"Every time I go to the outfield it's like coming home. The outfielders are all talented and speak well. I love being in the outfield again."

"I'm going to the outfield in a bit. Take your phone with you. Remember to bring me along when you guys play in the dugout."

(ps: The protagonist is not a time traveler, I haven't read the comics.)
