Option 2: As it happens, I genuinely do have a little experience in this prompt because I used to play field hockey. Never at much of a high level because I had no real athletic talent, but on an amateur level at university and a little bit after, and I did actually train for it. I played in goal rather than outfield but the principle's the same. For me, the best cross-training I ever did was working on my reflexes by playing tennis - I was absolutely dreadful at it from a tennis playing perspective but as a way to get sharper and feel looser there aren't many better ways to prepare for having a ball fired at you at high speed than just having a ball fired at you at high speed. Obviously playing hockey I didn't have the big surface area of a racquet to work with and I could just do my best Hasek impression by launching myself at the ball, but it seems to work.
