Tracing JerAx's Career From OG's Titles to Evil Geniuses

Few support players in Dota 2 history have a résumé that includes two trophies from The International, the game's annual world championship. Jesse "JerAx" Vainikka does, and his path to getting there, and what he did once he had them, says a lot about how a long competitive career in esports can bend: years of grinding through small teams, a run at the very top, a retirement, and a comeback that did not go the way anyone hoped. This guide walks through each stage of that career in order, from his first Finnish teams through his two championships with OG and his short stint with Evil Geniuses, using only what teams, organizers and established outlets have published about him along the way.

Career dates and results as recorded by Liquipedia's Dota 2 wiki and by outlets covering each move at the time.

Early years in the Finnish scene

JerAx's path into professional Dota 2 started in 2013, when he joined QPAD Red Pandas, first as a trial player and then as a full member, after a brief spell with a team called Rat in the Dark. Over the next two years he moved through a run of short stints that is typical of how support players broke into the scene before the game had the stable team infrastructure it has today. From 2014 into January 2015 he played for a Finnish lineup known as 4 Anchors and later as Sea Captain, where he held the position four role and acted as the team's in-game captain, the player who calls the team's rotations and shot-calls during a match.

That was followed by short runs with Team Tinker in early 2015, then MVP HOT6ix through the middle of that year, and 5Jungz for a few months after that. None of these stops lasted long, but they gave JerAx match experience against a wide range of regional opposition, and by October 2015 that experience had caught the attention of one of the scene's bigger rosters.

That pattern of frequent, short-lived team changes was common for support players in the mid-2010s Dota 2 scene, before most regions had the kind of long-term organizational backing that lets a roster stay together through a full season regardless of results. A player's reputation in that period was built match by match and tournament by tournament, rather than through a single marquee contract, which makes JerAx's later run of stability at OG stand out even more by comparison.

The move to Team Liquid

In October 2015, JerAx signed with Team Liquid, one of the organizations that would go on to define the next decade of Dota 2's competitive scene. He spent roughly ten months with the team, through August 2016, playing support behind a roster built for international events. Liquid reached the top eight at The International that followed, a respectable finish for a team still settling into its final form, but not yet the kind of run that makes a career.

The stay at Liquid mattered less for the results it produced than for what came after it. When the post-tournament shuffle period opened in August 2016, JerAx left Liquid and joined OG, the organization with which his career would turn into something much bigger. It is worth noting, for context on what a "shuffle" means in Dota 2: most roster changes across the scene happen in a short window right after The International each year, when players' contracts typically expire and teams rebuild around who stays and who leaves.

Settling in at OG as position four

JerAx joined OG in August 2016 and held the position four role there for more than three years, one of the longest single-team stretches of his career. Position four in Dota 2 is a support role built around flexibility: rather than sticking to one hero or one job every game, a position four player is expected to roam the map, set up kills in the early game, and adapt the hero they play to whatever the draft calls for. It is widely regarded as one of the hardest roles to play consistently well, because it rewards reading the game rather than following a fixed script.

Before OG's two International wins, JerAx helped the team pick up two Dota Pro Circuit Majors, in Boston and in Kiev, part of the steady run of results that built OG's reputation as a team capable of beating anyone on a given day, even when its results across a full season were less consistent. The Kiev Major win came on May 1, 2017, when OG beat Virtus Pro 3-2 in the final series, according to a report published that day by Yahoo Sports. The organization went through a roster overhaul around the middle of 2018, but JerAx was one of the players who stayed through it, alongside captain Johan "N0tail" Sundstein. That continuity, through a period when other organizations were rebuilding from scratch, is part of why OG's run over the following two years is often described as having grown out of an unusually stable core rather than a roster assembled specifically to chase one tournament.

Back-to-back: The International 2018 and 2019

OG's roster, with JerAx at position four, N0tail as captain, Anathan "ana" Pham on the carry role, Sébastien "Ceb" Debs, and Topias "Topson" Taavitsainen, won The International 2018 in Vancouver, taking the title and the bulk of a $25,532,177 prize pool, according to a history of the tournament's results compiled by the esports outlet Hotspawn. OG's share of that pool came to $11,234,158, a little over 44 percent of the total.

The grand final itself went the distance: OG beat the Chinese roster PSG.LGD 3-2 in a best-of-five series, according to a report from the esports outlet Rotowire published the day of the match.

A year later, the same core returned to defend the title at The International 2019, held in Shanghai. OG won again, beating Team Liquid, JerAx's former team, 3-1 in the grand final, according to a report from the esports outlet OneEsports published the day of the match. That win made OG the first team in the tournament's history to win it twice in a row, a feat OneEsports described as making the roster the first-ever double Aegis winners, referring to the Aegis of Champions, the trophy awarded to each year's International winner. The 2019 pool was larger still: Hotspawn's figures put the total at $34,330,068, with OG's winning share at $15,620,181, about 45.5 percent of the pool.

No other organization has repeated that back-to-back feat since, which is part of why that OG roster, JerAx included, is remembered as one of the strongest the game has produced.

Why that OG roster worked

Outlets covering OG's run at the time, including PC Gamer's report from the TI9 final, pointed to the team's willingness to draft unconventional heroes and lineups rather than copying what other top teams were doing. JerAx's position four play was often central to that approach: because the role does not lock a player into one hero pool, a position four player who reads the draft well can push a team toward strategies opponents have not prepared for. That flexibility, paired with a captain in N0tail who was willing to commit to those picks in the biggest matches of the year, is the combination most retrospectives on the roster point to when explaining why it beat the rest of the field twice.

The retirement

JerAx announced his retirement from professional Dota 2 on January 27, 2020, in a statement reported at the time by the esports outlet OneEsports. He said he no longer had the willingness or the passion to keep playing at that level, describing the yearly grind of top-level competition as something that had left him feeling apathetic, exhausted, and numb. He talked about the game itself as an endless puzzle, and said the feelings that first drew him to it had faded.

OG was already short-handed heading into that announcement: its star carry player ana was taking an extended break of his own at the same time. The organization said it planned to announce replacements for both players within a day or two of JerAx's statement, and that it would hold a tribute event for him. That transition period marked the effective end of the roster that had won two straight Internationals, even though N0tail, Ceb and Topson stayed with the organization afterward.

Retirements of this kind are common enough in Dota 2 that they rarely surprise the scene: a title run followed by a step back is one of the more familiar shapes a top player's career takes once the pressure of repeating a result like that sets in.

The return: joining Evil Geniuses

Nearly two years later, on November 20, 2021, JerAx returned to competitive play, signing with Evil Geniuses for the 2022 Dota Pro Circuit season. The move was reported the next day by the esports outlet Upcomer, which described the new lineup as built around captain Andreas "Cr1t-" Nielsen at hard support, with JerAx and Egor "Nightfall" Grigorenko, who moved from a carry role to the offlane, replacing two players who had left in that year's shuffle, Tal "Fly" Aizik and Daryl "iceiceice" Koh Pei Xiang. JerAx took the position four role again, the same job he had played throughout his years at OG.

A title does not buy back the form a player left on the table when they stepped away. Evil Geniuses' 2022 season showed how hard that gap can be to close, whatever name is on the jersey.

A difficult season

The comeback did not produce the results either side hoped for. Evil Geniuses struggled through the 2022 Dota Pro Circuit season, a stretch that included visa problems that kept the team from training together as a unit at the start of the year, according to comments JerAx made on a podcast at the time, in which he also described himself as out of practice and uncertain in his read of the game after his time away from competition. The team's results matched that difficulty: at the ESL One Stockholm Major, Evil Geniuses finished 13th with a 2-10 record across the group stage, a result reported by the esports outlet OneEsports.

On the final day of that Major, in May 2022, OneEsports reported that JerAx had been removed from Evil Geniuses' lineup on Valve's official registration page for the Dota Pro Circuit, before the organization had made any public statement about the change. The report tied the move to the team's poor run at the Major and its wider struggles that season, though it noted that Evil Geniuses had not given an official reason at the time of publication.

From player to coach

JerAx's next stop was off the server rather than on it. From June to December 2022, he worked as a coach for Team Liquid, the organization where he had played support roughly seven years earlier before his move to OG. Coaching gives a former player a way to apply the reads and instincts built over a decade of competition without needing the same reflexes a starting position four role demands in-game, and it is a common next step for players stepping back from active rosters in Dota 2 and in other team-based esports alike.

A coaching role is a different kind of pressure from a playing one. Rather than executing calls in real time, a coach spends the bulk of a season reviewing scrims and matches with the players, preparing drafts against specific opponents, and helping a roster settle disagreements about strategy before they show up on stage. For a player who had captained his own team in his earliest days in Finland and later operated inside two of the most drafting-heavy rosters of his era at OG and Evil Geniuses, that kind of behind-the-scenes role was a natural next step once his run as an active player ended.

Public records of his career do not show him holding a competitive playing or coaching role since that stint with Team Liquid ended in December 2022. Any claim about where he stands today in the scene would need its own dated reporting rather than an assumption carried over from his past teams, which is why this guide treats his OG and Evil Geniuses years as history rather than as a current roster status.

What JerAx's career shows about the position four role

Looking back across the full arc, from the Finnish regional scene through two championships and a comeback that fell short, JerAx's career is a useful case study in how differently a single role can be played at different points in a career. At OG, he was part of a roster that used the position four's flexibility to out-draft stronger-looking opponents on the biggest stage in the game. At Evil Geniuses, the same role on a different roster, with a different meta around it, could not recreate that result, despite reuniting him with a similarly aggressive captain in Cr1t-.

That contrast is part of why support players are judged less on raw statistics than on how well a specific roster fits together, and why a single championship run, however dominant, does not guarantee that the formula travels to a new team or a new season. JerAx's two Internationals remain among the most decorated results any position four player has produced, and his short second chapter at Evil Geniuses is a reminder of how much of competitive success depends on timing and roster chemistry, not talent alone.

Why this history still matters

For readers newer to Dota 2, JerAx's career offers a compact example of how far a player can travel inside one role, from small regional teams with no stability to the top of the sport's biggest event, twice. For longtime followers of the scene, it is also a reminder that even a two-time champion's comeback is not guaranteed to work, and that organizations and players alike treat those attempts as real competitive bets rather than sure things. His case sits alongside those of several other champions from that era who tried, with mixed results, to return to the game that made their names, a pattern worth keeping in mind whenever a decorated player announces a comeback of their own.
