Doublelift

CLG prime would attend the 2012 MLG Fall Championship in Dallas on November 2 through 4th. In the first round they faced the Korean powerhouse NaJin Sword, where they were routed in two lopsided matches. Falling to the losers bracket, CLG Prime would sweep Curse Gaming in round one, and then pick up a close 2-1 series against another NA team Dignitas. They faced their sister team CLG EU in Round 3 and lost 2-1 and were eliminated from the tournament. CLG Prime finished in 4th with $2,000 in winnings.[7]

On February 27, 2013, CLG participated in the Riot Season 3 North American League Championship Series Spring Split.[8]

CLG and Peng were fined on January 6, 2015 after being found guilty of poaching ZionSpartan. CLG was fined $2,000 while Peng was fined $2,500. Furthermore, CLG was restricted from fielding ZionSpartan as a player or coach for the first week of the 2015 LCS Spring Split.[9]

For the first eight weeks of the spring split, CLG were never lower in the standings than tied for second place. At the end they lost a second-place tie breaker to Cloud9 and so ended up in third place in the regular season. Ultimately, CLG lost to Team Liquid in the quarterfinals and ended the split tied for fifth place with Gravity Gaming.[10]

Peng was benched during the Summer LCS due to an injury incurred from playing basketball.[11]

In August Peng helped CLG win their first ever LCS Split playoff title.[12] The victory also qualified them for the 2015 League of Legends World Championship. At Worlds CLG failed to make the bracket and finished 12/13th. On October 31, CLG informed Peng that they were not going to re-sign him. Immediately after CLG released a statement,[13] Team SoloMid announced that Peng would be joining as their new AD Carry, replacing long tenured AD Carry WildTurtle.[14]

Before the start of the 2017 season, Team SoloMid announced that Peng would be taking a hiatus from professional League of Legends during the spring split, saying "it's time for a small break." While he would remain contracted to the team, he would be streaming full-time until his return to professional play in the summer when, according to Team SoloMid owner Andy Dinh, he would have to compete with his replacement to return to the starting roster.[15] In the past, Peng has spoken out about the never-ending competitive schedule for professional League of Legends. After representing North America in the All-Star 2013 in Shanghai, Peng said in a Reddit AMA "I'm just tired of playing all day every day, and I want a goddamn break but it's not possible to get one."[16] In a Reddit AMA in 2014, Peng said "Most people who look at pros think that we live the dream life when in reality you either practice 16 hours a day or lose and end up frustrated. Sometimes you practice 16 hours a day and still end up losing."[5] One month later, Team SoloMid announced that WildTurtle would be Peng's replacement for the 2017 spring split.[17] In an interview, teammate Bjergsen agreed with Dinh's initial announcement that Peng would need to compete with his replacement, saying "I want WildTurtle to succeed and I wasn't just sitting around waiting for Peter because I wanted someone who was committed, and like I said I was disappointed and I felt he wasn't very committed. I didn't feel like he should just have the luxury of going out and making a lot of money [streaming] and returning to the team... No matter how good of a friend they are to me, if someone decides he's just going to take six months off and he thinks he's can just reenter the team, that's just not okay with me because I think everyone has to earn their spot."[18]

More than halfway through the spring season and threatened by relegation, Team Liquid announced that Peng would temporarily be joining the team and would be released back to Team SoloMid at the end of the spring split,[19] sparking controversy due to concerns of a conflict of interest when Peng inevitably competed against Team SoloMid while signed to Team Liquid. Team Liquid owner Steve Arhancet responded that Riot Games approved the trade after the team demonstrated that no other player in that role would be suitable for the team.[20]

Before the start of the 2018 NA LCS season, Team SoloMid announced they would be parting ways with Peng, citing a desire for a stronger shot-caller in the bottom lane.[21] On the same day, Team Liquid announced Peng would be returning along with his ex-Counter Logic Gaming teammates Xmithie and Pobelter.[22] The team finished 4th place in the Spring Split regular season, securing a spot in the playoffs with a 12-8 record behind his former team TSM.[23] Team Liquid defeated Cloud9 3-0 in the quarterfinals and Echo Fox 3-1 in the semifinals to make it to the Team Liquid's first ever final.[24]

A week before the final, Peng learned that his mother Wei Ping Shen was killed and his father Guojon Peng seriously injured after his older brother Yihong Peng allegedly stabbed them in their family home in San Juan Capistrano California. Peng posted on Twitlonger "I'm still processing this news and joining up with my dad and little brother to make sure they're ok and the proper arrangements are being made. I'll likely be quiet on social media while I work through this. I hope you all understand and support me as you always have in the past."[25] In an interview with Machinima in 2013, Peng had said his older brother was his biggest influence on his life and career, and that he had regrets with his falling out with his parents and wished to make amends in the future, but with his busy career "right now I can't do that, I'm too busy."[4] Despite the pressure faced during this event, Steve Arhancet, owner and co-CEO of Team Liquid, announced that Doublelift would not be taking time off and was determined to play in the final as planned.[26] In the final, Team Liquid convincingly defeated 100 Thieves 3-0 and won its first league championship.[27]

In the summer split 2018, Doublelift and Team Liquid picked up where they left off in spring. A tightly contested regular season saw Team Liquid come out with the number one seed by only a single game over Cloud9, qualifying them for a bye in the first round and a guaranteed spot in the semi-finals. Matched up against 100 Thieves, Doublelift and Team liquid cruised to a 3-1 series victory to move on to a spot in the finals against Cloud9. On the eve of the NA LCS finals, Doublelift was awarded a long-awaited NA LCS MVP for the summer split. This was his first MVP award.[28] Team Liquid easily defeated Cloud9 3-0 in the finals to capture back to back North American LCS titles and looked towards a strong showing at Worlds 2018.[29] However, they were eliminated in the group stage by KT Rolster and Edward Gaming.

Fresh out of a group stage exit at Worlds 2018, Team Liquid announced the signing of Jensen and former world champion CoreJJ to the midlane and support positions respectively. With their newly revamped roster, Team Liquid finished 14-4 on the 2019 Spring Split advancing to the Spring finals to face Doublelift's former team TSM. Team Liquid dropped the first two games of the series, and on the brink of elimination, Liquid picked up three straight wins to beat TSM in the best of 5 series, thus earning Doublelift his 6th championship and 3rd straight title win. Despite coming off of a strong performance in the Spring playoffs, Team Liquid struggled initially in the group stage of MSI 2019, but with a strong finish to the group stage they secured a 4th place seeding in the playoffs. This marked the first time Doublelift making it out of groups stage at an international tournament. In a surprising upset, the 4th seeded Team Liquid defeated the defending world champions, Invictus Gaming, in a four game series. Team Liquid advanced to the finals to face G2 Esports, where they were ultimately defeated in a 3-0 sweep.

After a disappointing finish to MSI 2019, Liquid started out the 2019 LCS Summer Split with a poor 2-2 start, tying them for 4th place. However, they regained their footing and managed to take sole ownership of first place in a few short weeks. They once again finished atop the LCS with a 14-4 record. In the summer playoffs, Liquid beat Clutch Gaming in a close five games series to secure their place at Worlds 2019. They advanced to the summer finals where they met the second seeded Cloud9. It was a tightly contested series with Liquid winning the first game of the series, but dropping games 2 and 3 to Cloud9. Liquid managed to turn the tables and win games 4 and 5 to secure their 4th straight LCS trophy and Doublelift his 7th championship overall. This victory made Doublelift the player with the most titles in NA LCS history. At Worlds 2019 Liquid had a lackluster 3-3 performance which led to them once again being eliminated in the group stage.

With their premature exit from Worlds, Team Liquid parted ways with their jungler, Xmithie and signed former Fnatic Jungler, Broxah. Prior to the start of the spring 2020 split, Broxah had visa issues preventing him from joining them for the start of the spring season. Team Liquid performed very poorly, a far cry from their domination of the years prior. Midway through the split, Doublelift was benched in favor of Team Liquid Academy ADC Tactical. According Doublelift, this decision stemmed from his apparent lack of motivation to begin the 2020 spring split. Doublelift publicly apologized to his teammates for his attitude, and promised to work harder to return to the LCS stage. Doublelift returned to the starting lineup the following week, but ultimately Liquid finished the split in 9th place and did not make 2020 Spring Playoffs. Doublelift and Team Liquid's failure to qualify for playoffs marked the first time in LCS history that the reigning champion not qualify for the following split's playoffs.

With a disappointing finish to Spring 2020, Team Liquid traded Doublelift to Team SoloMid for the 2020 Summer Split.

Doublelift's move to TSM reunited him with Bjergsen and Biofrost once again. The starting roster for TSM included Brokenblade in the Top Lane and Spica as the Jungler. TSM had a shaky start to the first half of the split, with a record of 6-3. Although they were third in LCS, critics deemed their wins unconvincing and some considered their record as not properly reflective of their actual skill level. In the middle of the split, Biofrost was replaced by TSM Academy support Treatz, with the team citing better communication and possibly playmaking as the deciding factors. In the 2nd half of the split, TSM once again went 6-3. Doublelift's performance during the summer regular season was regarded as subpar and a far cry from his dominance of years prior. TSM finished the regular split in 4th place with a 12-6 record.

In playoffs, TSM faced the fifth seeded Golden Guardians in the upper bracket of the double elimination tournament. Although it was projected to be a close series, Golden Guardians unexpectedly swept TSM 3-0 with the TSM bot lane being perceived as the weak link in the loss. After the first round defeat, the team subbed Biofrost back in place of Treatz. The moved was in part cited to the existing synergy between Doublelift and Biofrost, especially for laning phase. TSM would drop to the bottom half of the elimination bracket to face the 8th seed, Team Dignitas. TSM swept Dignitas in convincing fashion, as expected. With the Golden Guardians loss to Team Liquid, TSM had to face them once again in the 2nd round of the lower bracket. Golden Guardians took the first two games of the series, but behind outstanding performances from Bjergsen, Spica, and Brokenblade, TSM managed to come back and reverse sweep the series. In the next round, TSM faced Cloud9 in order to determine the final seed for the 2020 World Championships. TSM won the series against Cloud9 3-1 and qualified for Worlds. With Team Liquid losing to FlyQuest in the upper bracket, Doublelift faced his old team in order to move on to the summer split finals. TSM defeated Team Liquid 3-2 after a grueling five game series. Critics cited improved play by Doublelift as one of the main reasons behind the win. TSM faced FlyQuest in the finals, with TSM once again winning 3-2 after a tough five game series. This win marked Doublelift's 8th NA LCS title.

Successfully completing their miraculous lower bracket run, Doublelift and TSM headed to Shanghai for the 2020 World Championships as the NA 1st seed. During the tournament, TSM was placed into Group C along with the LCK 3rd seed Gen.G, the LEC 2nd seed FNC, and the LPL 4th seed LGD. Doublelift was once again unable to advance past the group stage, after TSM went 0-6 in the group stage.

In November 2020, Doublelift announced on his twitter account that he was retiring from professional League of Legends, thus concluding a storied career which spanned nearly a decade.
