Ace of Diamond is one of the definitive modern baseball manga, and also one of the longest. Eijun Sawamura is a loud, raw country pitcher with an unusual natural pitch who lands at Seido, a powerhouse Tokyo baseball school stacked with talent. Instead of becoming an instant star, he has to claw for playing time against gifted teammates, especially a cool, brilliant catcher and a genius rival ace. Across its original run and its sequel, it follows Seido's grind toward the national tournament with a huge cast and meticulous attention to the sport. It's complete now, though "complete" here means a very, very long read.
The baseball is the real draw, and it's excellent. The series goes deep on strategy, pitch selection, and the mental game, and it wrings genuine tension out of a single at-bat. When a big game is on the line, the pitch-by-pitch drama is as gripping as the genre gets.
The ensemble is the other strength. Seido is full of distinct players, and the internal competition, especially the fight for the ace's spot and the battery dynamic between pitcher and catcher, gives the team real texture. You get invested in these guys as teammates and rivals, which makes the wins and losses land.
Sawamura himself is a great engine for it. He's an energetic, hard-working underdog who has to earn everything, and the rivalries around him keep raising the bar. Once you're settled into the team, the games become genuinely hard to stop reading.
The size is the obvious barrier. This is an enormous series, and the pacing is slow: a single game can stretch across many chapters, and getting through the whole thing is a major time commitment. If you want something brisk, this is the opposite.
The large cast can also be hard to track, and the underdog-grind structure, train, compete, big game, repeat, recurs enough that it can feel like a slog in stretches. It rewards patience and investment more than casual reading, and not everyone will want to give it that.
Ace of Diamond is a great baseball manga for readers willing to commit, with some of the most detailed, tense sport in the medium and a team you grow genuinely attached to. Go in ready for a long haul rather than a quick read. If you love the sport or sink-in sports dramas, it's richly rewarding, and it's complete now. If you want fast pacing or a short, contained story, its sheer length will wear you down.

Very long. The original run is 47 volumes and the sequel adds 34 more, so it's a serious commitment, though the whole manga is complete now.
It helps. The series goes deep on strategy and pitch-by-pitch detail, so baseball fans get the most out of it, but the team drama can pull in newcomers too.
Yes. Both the original series and the sequel Act II have concluded, so you can read the complete story.
