Mathew "xSojin" Alexander Perez is a League of Legends esports player, currently coach for Counter Logic Gaming.


Mathew "xSojin" Perez was born in Moreno Valley, California. He has played videogames since he was very young, and prior to playing League of Legends was a console gamer. He primarily played Kingdom Hearts, Jak and Daxter, and Uncharted 2. He began playing League of Legends partway through Season 2, where he primarily played jungle in Solo Queue.

2014 Season[edit]

In January 2014, Perez joined Kubiko as their jungler. Kubiko attempted to play in to the 2014 NA Challenger Summer Series, but fell to team LoLPro in a best of one match. In June 2014, he parted with Kubiko to join the Ranked 5ss team Monstar Kittenz as their jungler.

2015 Preseason[edit]

Monstar KittenZ climbed the Ranked 5's ladder, and qualified for the LCS 2015 Season Expansion Tournament but then lost to compLexity.White 1-2 in the first round of the tournament. After the Expansion Tournament, xSojin left Monstar Kittenz.

2015 Season[edit]

xSojin joined TSM Darkness before the start of the third week of the NACS Spring Season, replacing Azingy as their starting jungler after his move to Team Dignitas. He jungled for one week, then didn't play in the fourth week, and then started as AD carry in the last week after t3azer was revealed to have leaked scrim footage to Team Fusion. The team finished fifth overall in the season, after winning a tiebreaker game against CLG Black. After multiple renamings of the team, xSojin left shortly after the start of the 2015 NACS Summer Season.

2016 Preseason[edit]

xSojin joined Tabula Rasa for the HTC Ascension tournament.
