I was having a hard time with this one. I swear they sometimes throw impossible pitches. I angled the bat in a weird way because it helped me time the hits. It's something like, once the shadow is obscured by the bat, I swing.
Luckily the game is pretty generous and doesn't always count foul balls as misses. I fouled a bunch toward the end.
