Masaya "aMSa" Chikamoto has been on a tear at this weekend's Smash Summit 6, and yesterday he pulled off an upset on one of Melee's best players.

Tekken 7 pro Choi "Saint" Jin Woo is one of the top players in the game. He took second at both Evo 2017 and last year's Tekken World Tour finals. So when fellow pro Tanukana eliminated him from Beast Arena in Hong Kong this morning, you can imagine how exciting that must have felt.

In the last block of the night at our "Can You Beat An Esports Champion?" event, Du "NuckleDu" Dang was the first pro to drop all day. Kevin "Die3mini0n" Landon, a professional Street Fighter player himself, took down NuckleDu in a tense mirror match-up.

It's not often you see upsets like the one that happened today in Kiev, Ukraine, where the lowest seed of the tournament not only pushed the top seed to a game three, but eliminated them altogether.

The snarky pup from Duck Hunt isn't the most common competitor in Smash 4. Though he has his defenders, players like Raito have had to work to show that the dog's D-tier ranking doesn't prevent him from taking games off the best of the best. At CEO Dreamland, Raito and other Duck Hunt Dog players are having their day.

This weekend's Frostbite 2017 is a tournament solely devoted to Super Smash Bros. for Wii U. In the pools, anyone is fair game, as Elliot "Ally" Bastien Carroza-Oyarce learned after getting upset by a relatively unknown Kirby player.
