Ok, I remembered something i read a long ass time ago, it was a manga, had baseball as its foundation, the team were deadbeats and the new pitcher wanted to play, but cant due to messed up arm.

anyone remember something like this? oh, i think the batter also beat someone to hell with a bat in the first 10 pages.

I've never read the manga, but maybe Rookies?

Nope, though I do have that manga it wasn't it.

Is it Bench by KISHIMOTO Masashi?

No, that wasn't.

I feel like this can't be it, since it would be too obvious... But is it H2?

Sorry this one is late, got busy and this tab got burried
no its not

What i mean by really detailed was pages of the manga made me stop reading and just look at it thinking 'damn, that is well drawn"

Thinking back on it now, if things like the baseball on the 2page spread weren't rotoscoped, the person drawing it has a fair amount of skill.
