As Seattle Mariners catcher Cal Raleigh — known as “Big Dumper” — becomes the baseball season’s breakout star, he is making it clear his best isn’t behind him.

The Seattle Mariners catcher has become the MLB's unlikely breakout star after winning the All-Star Home Run Derby to cap a monster first half of the season.

Several professional sports teams have had some fun with the moment, poking fun at it through posts on social media.

If you weren’t aware of who Cal Raleigh is, you definitely weren’t aware of him being known as the “Big Dumper,” and MSNBC’s Mika Brzezinski was baffled by the latter. Raleigh enjoyed a historic first half of the season that has the Seattle Mariners catcher on pace to break the American League Home Run record.

Clayton Kershaw trolls Cal Raleigh after getting him out in All-Star Game: ‘Suck it, Big Dumper!’ Whoever came up with the idea to mic up Clayton Kershaw for the MLB All-Star Game in Atlanta deserves a raise.

While many fans have likely heard the Mariners star’s nickname, “Big Dumper,” the Yankees’ broadcast Tuesday on YES Network made sure to drill things home to its viewers.
