Ace of the Diamond (Diamond no Ace) is widely considered one of the greatest sports anime ever, and I absolutely agree. For me, it’ll always be my #2, right under Haikyu!!
The original series started in October 2013 and ran for two seasons before taking a major break. In 2019, Ace of the Diamond came back with Act II and a third season.
Ace of the Diamond series has a total of 178 episodes across all 3 seasons (Act I and Act II). Of these 178 episodes, five (2.8%) are complete fillers and two (1.12%) are partial fillers. Luckily, the anime is mostly canon with 171 canon episodes (96.08%).
The production team at Madhouse and I.G has done a great job with this anime. Not only is the quality great but the so-called “five fillers” are just recaps for people who were watching weekly at the time.

3. Which Diamond no Ace fillers can you skip?
Filler episodes of Diamond No Ace are just recaps to help you catch up with the series. They aren’t important at all so you can skip them if you’re binging all three seasons.
