Lasse Aukusti "MATUMBAMAN" Urpalainen made his presence felt quickly in Dota 2, establishing himself as one of the best players in Finland by winning Assembly Summer 2014 over a number of proven Dota 2 pros from the country. From there, he landed with all-Finnish super-team 4 Anchors + Sea Captain, alongside the likes of Jesse "JerAx" Vainikka and Kalle "Trixi" Saarinen.
4 Anchors + Sea Captain posted mixed results in a number of leagues and smaller events. The team fell just shy of qualifying for The International 2015 and disbanded shortly thereafter.
After becoming a free agent, MATUMBAMAN and Jerax joined 5Jungz, a new team formed around former Natus Vincere support player Kuro “KuroKy” Salehi Takhasomi. The team was quickly picked up by Team Liquid after winning Alienware Summer's End Cup and qualifying for the Nanyang Dota 2 Championships. MATUMBAMAN, KuroKy, and Ivan Borislavov "MinD_ContRoL" Ivanov would make up the core of Team Liquid for several years to come.
The team established itself as a high-end squad quickly by winning The Defense Season 5 and Dota 2 Champions League Season 6, but got slowed when it failed to qualify for the first Valve-sponsored Dota 2 major, the Frankfurt Major. Liquid bounced back and cemented itself as an unquestioned elite by taking second place at the Shanghai Major.
From there, the team won EPICENTER 2016 and took second in the Manila Major. This established Liquid as one of the favorites to win The International 2016, but instead the team posted a disappointing top-eight performance at the event.
This led to the departures of JerAx and mid laner Adrian "Fata" Trinks, with Amer "Miracle-" Al-Barkawi and Sam “BuLba” Sosale taking their place. The team failed to qualify for the Boston Major, which led to the eventual departure of BuLba and the addition of Maroun "GH" Merhej. This version of Liquid stuck together for an extended period of time and enjoyed consistently strong success.
The team made its live event debut by winning DreamLeague Season 6. The team continued to win notable tournaments throughout the year. Despite a disappointing performance at the Kiev Major, Liquid roared through the summer by winning StarLadder i-League Invitational Season 2, EPICENTER 2017, and DreamLeague Season 7. This was more than enough to earn the team a spot in The International 2017, which paid off in the form of an Aegis-winning performance.
The creation of the Dota Pro Circuit saw Liquid compete in a slew of minor and major tournaments throughout the year. The team fell short of the top on most occasions, but placed in the top four of five majors before winning the China Dota 2 Supermajor. MATUMBAMAN’s strong performance throughout helped the team earn a direct invitation to The International 2018 through the Dota Pro Circuit. The team failed to defend its title, but still posted a strong fourth-place finish at the event.
The 2018-2019 Dota Pro Circuit season started curiously for Liquid. The team took the first major cycle off without any sort of explanation, which was followed by the abrupt departure of longtime coach Lee "Heen" Seung Gon.
A first-place finish at the MegaFon Winter Clash suggested Liquid was back on track, but the team looked out of sorts in the Chongqing Major and DreamLeague Season 11. This put Liquid into a precarious position, but TL jumped up the Dota Pro Circuit rankings by taking second place at the MDL Disneyland Paris Major.
That put the team in line for a direct invitation for The International 2019 and gave them enough of a buffer to make a roster move to shake things up. After qualifying for the Epicenter 2019 Major, that roster move came in the form of Liquid kicking MATUMBAMAN after nearly four years with the team.
MATUMBAMAN was functionally traded to Chaos Esports Club in exchange for Aliwi “w33” Omar and served as one of the new players for the team as it relocated from South America to Europe. The team qualified for The International 2019 in its debut performance, but finished in last place.
Chaos EC dissolved following this, with MATUMBAMAN taking a short break from the game. He reemerged after a few months by becoming the new carry player for Team Secret.
MATUMBAMAN debuted with the team at ONE Esports Dota 2 World Pro Invitational Singapore, which placed top-six despite competing with a substitute. The new Secret made its full debut at the DreamLeague Season 13 major, which it won in impressive fashion.
