Yiliang "Peter" "Doublelift" Peng is the AD carry for Team Liquid.


Yiliang "Doublelift" Peng hails from Mission Viejo, California. Peng first discovered his love for video games through classic Nintendo 64 titles Star Fox and Golden Eye. After his brother got a computer, Peng frequently used it to play Diablo 1 and StarCraft. Since his brother would buy a new computer every few years, Peng soon came to own his own hand-me-down desktop. This allowed him to spend more time playing computer games such as DotA, WoW, and HoN with his brother and friends. Eventually they all left these games behind and moved to LoL.

Peng was eventually kicked out of his home by his parents after he had got back from DreamHack Summer 2011. Peng eventually moved in with Travis "Tnomad" Gafford prior to joining Counter Logic Gaming.

League of Legends Career

Known for his  Blitzcrank, Doublelift gained the attention of George "HotshotGG" Georgallidis in early 2011, and the two duo queued together. HotshotGG asked him to join Counter Logic Gaming as a substitute which he accepted, but soon moved to Epik Gamer for a starting position as their Support. Doublelift then moved on to unRestricted (now known as Curse Gaming), to become their starting AD Carry. He competed for Curse at LAN events such as IGN Proleague and IEM New York.

In November 2011, Doublelift left Curse and rejoined CLG, now as their starting AD Carry. [1] He has been with CLG since, through numerous roster changes and several LCS campaigns.

Doublelift represented North America in both the 2013 All Star tournament and the 2014 All Star tournament.

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

2015 Season

For the first eight weeks of the spring split, CLG were never lower in the standings than tied for second place, and the only reason they didn't receive a playoff bye was that they lost a second-place tie breaker to Cloud9 and so ended up in third place. CLG fans called the split CLG's "golden age," but the question still remained whether CLG could perform in the playoffs, especially after a dramatic comeback loss to Team SoloMid the first time the two teams met in the round robin. Ultimately, CLG were unable to perform in playoffs, as they lost to Team Liquid in the quarterfinals and ended the split tied for fifth place with Gravity.

Echoing their spring split performance, CLG started the summer split strong, in first place at the end of each of the first four weeks and then lost four games in a row to finish tied for fifth after week six. This time, however, they rebounded and ended the season in second, behind Team Liquid and with a 13-5 record. They received a bye in the first round of the playoffs and then swept both Team Impulse and Team SoloMid 3-0, to win their first LAN event since MLG Raleigh in 2011 nearly four years prior - and Doublelift's first ever - and receive North America's top seed to Worlds. Despite having a relatively easy group draw with KOO Tigers, Flash Wolves, and paiN Gaming, CLG didn't advance from their Worlds group, ending with a 2-4 record including a loss to paiN.

2016 Preseason

On October 31st, 2015, Doublelift left CLG, after over four years with the team.[3] He joined Team SoloMid.[4] TSM's roster for IEM San Jose included Hauntzer, Svenskeren, Bjergsen, Doublelift, and kaSing.[5] TSM defeated LGD Gaming but then lost to Origen in the semifinals. After IEM, kaSing departed the team and was replaced by former star Fnatic support YellOwStaR.

2016 Season

TSM's NA LCS season started out rocky, with a 50% winrate for the first three weeks. Regardless, they were invited to IEM Katowice in March. There, they dropped their first game to the Korean Challenger team Ever but recovered in the loser's bracket before losing in the semifinals to eventual tournament winners SK Telecom T1 and finishing tied for third place with Royal Never Give Up. After returning to North America, their rocky season continued, and they finished in sixth place, the lowest they'd ever finished in the history of the LCS, with a huge comeback loss to Echo Fox in the last game. Guaranteed to face first-seed Immortals if they were even able to beat Cloud9 in the quarterfinals, TSM seemed poised to have their lowest playoff result in the history of the LCS as well.

However, after signing the well-known sports psychologist Weldon in the break before playoffs, TSM showed significant improvement as a team. They easily defeated Cloud9 3-1 in the quarterfinals and went on to crush Immortals 3-0 in the semifinals, although a lot of their win over Immortals was blamed on surprising draft picks by their opponents, including a top-lane Lucian in Game 1 and no sign of the heavily-in-meta Ekko from either team. In the finals, TSM faced CLG, a matchup with an even more heated rivalry than normal due to Doublelift's team switch prior to the season's start. Ultimately CLG won 3-2, and TSM finished the split in second place, out of reach of the Mid-Season Invitational.

Support YellOwStaR departed TSM during the mid-season break to return to Fnatic, and after a Korean bootcamp during the mid-season break to try out new support players, TSM signed Dream Team's Biofrost as his replacement. Despite being a LCS rookie, Biofrost proved himself almost immediately at the start of the Summer Season. TSM didn't lose a single series until week 8, where they fell 0-2 to then ninth-place Phoenix1. That series was their only loss of the regular season, and they also nearly swept the Playoffs, defeating CLG 3-0 and then Cloud9 3-1 in the finals, qualifying them for the World Championship with North America's first seed.

After their summer split performance, TSM were expected by many to advance out of the group stage, but after being drawn into group D alongside the eventually second-place Samsung Galaxy, Royal Never Give Up, and Splyce, TSM dropped three games in the group stage including two to RNG; they lost a second-place tiebreaker with the Chinese team based on head to head and did not advance. Soon after Worlds, TSM announced that Doublelift would be stepping down from the active roster for the 2017 spring split, and the team forfeited their IEM Oakland seed.[6]

2017 Season

Although Doublelift was a streamer throughout most of the 2017 NA LCS Spring Split, he would briefly join Team Liquid near the end of it. After helping the team increase their performance and survive relegations, he returned to Team SoloMid in the summer. During the Summer Season after Doublelift's return and WildTurtle's departure to FlyQuest, TSM was expected to dominate the split. They would finish 1st in the regular season with 14 wins and 4 losses but were not back to their dominant selves. In the playoffs they defeated Team Dignitas 3-1 in the semifinals and then took down Immortals 3-1 in the finals to capture their third title in a row which was a first in NA LCS history. The win also qualified TSM for the 2017 Season World Championship.

They were seeded in a group that looked weak on paper and consisted of a shaky Flash Wolves, and untested Misfits and a questionable Team WE. TSM started off well with a 2 wins and 1 loss in Week 1 but then in Week 2 they performed worse and went 1-2. Having to play a tiebreaker against Misfits, TSM lost and were eliminated from Worlds in the group stage yet again in a fashion similar to last years'. Doublelift left TSM in November and joined Team Liquid in the same month.
