Cal Raleigh, the Seattle Mariners’ star catcher, has become one of MLB’s most recognizable figures in 2025, thanks to his explosive power at the plate and his unforgettable nickname, “The Big Dumper.” The moniker originated in 2020 during the pandemic when Raleigh’s teammates at the Mariners’ alternate training site playfully noted his distinctive physique during drills.

The nickname gained mainstream traction during a 2025 Yankees broadcast when cameras zoomed in on Raleigh’s batting stance, prompting announcer Michael Kay to hilariously explain its origin. The combination of Raleigh’s power-hitting and the nickname’s absurdity created perfect meme material, endearing him to fans beyond Seattle.
