[1] YellOwStaR first joined the professional League of Legends scene after being picked up to play for eSports organization, Against All Authority in September 2010.

In the semifinals, YellOwStaR and aAa fought against the American powerhouse Team SoloMid, and were able to best the US players and advance to the winner finals bracket.

He played in few major tournaments, such as IEM Season VI - Global Challenge Cologne where they placed 4th, but left the team to rejoin a reformed aAa.

Tension and rocky performances at tournaments in the months after, led to YellOwStar and his bot lane support partner, nRated, leaving aAa and rejoining Millenium in June 2012 for a test period.

YellOwStaR and his team were unable to take a game in the set, ending 2-0, but still placed 2nd overall and earned a spot for the trip to Los Angeles.

With the North American and European community extremely excited for the amped up events of LCS, Season 3 began with Riot's new league of a 10-week series with the continent's best teams playing against another.

Due to Fnatic's performance in the Spring Playoffs, they had qualified to compete at All-Star Paris 2014, along with other regional winners from around the world.

Fnatic could not break into the top 2 until Week 7 of the split, at which point their main rivals Alliance were already a considerable distance ahead of them in the race for 1st place.

After being invited to the tournament, the departures of Rekkles, xPeke, and Cyanide meant that Fnatic and YellOwStaR would not be able to compete at IEM Season IX - Cologne.

Now with Rekkles on the roster instead of Steeelback, YellOwStaR and the team went into the Summer Season with confidence running high after their performance on the international stage.

Fnatic managed to finish the regular season with a perfect, unbeaten 18-0 record - and became the first team to achieve this in League Championship Series history.

In the quarterfinals, Fnatic beat EDward Gaming 3-0 before suffering a 3-0 loss to KOO Tigers in the semifinals, putting an end to their campaign.
