@Dunciboy and @VyseGolbez I won the baseball game on my first playthrough, only because I resetted whenever Rin got bad stat increases since she’s the pitcher. I made sure that she learned all her pitching skills (especially the upgraded version of Raging Meow Ball.) The strategy I employed was to hope Rin would strike out all the batters so that the rest of the team wouldn’t have to do anything. The few times a batter did hit the ball, Kurugaya or Haruka would catch it. It’s kind of a time-consuming strategy so I wouldn’t recommend it unless you really want to win the baseball game early or you really like Rin. I haven’t played the Perfect Edition yet, but I assume this tactic still works?
