Raymond "kaSing" (▶️ listen) Tsang (Hanzi: 曾家誠) is a League of Legends esports player, currently support for BT Excel.


Raymond "kaSing" Tsang was born in London, UK in 1993. He has also lived in Hong Kong and currently lives in Berlin, Germany. Tsang grew up playing multiple titles, including Maplestory, Gunbound, and Dota 1 and 2. He switched to League of Legends when he had a computer that was unable to run any other game but eventually came to enjoy it. Outside of gaming, Tsang received a BTEC IT Level 3 Extended Diploma in college and plans to study computer science if he continues with his education.

Season 3[edit]

Yerrow's first major attempt to break into the League of Legends pro scene was with the team Dexter Is Actually Evil in early Season 3; however, he was unable to play in the Summer Promotion Tournament qualifier, and his team lost to Team Mistral. After leaving that team, KaSing went on to play for British Tea Time, a team that was acquired by Dignitas to form Team Dignitas UK. Yerrow stayed with Team Dignitas UK until January 2014, when the team disbanded.

2014 Season[edit]

Yerrow finally made it into the LCS with SUPA HOT CREW, which he joined in the fifth week of the summer split, replacing former starting support player wewillfailer; at this time he also changed his name to kaSing.

On October 2, 2014, KaSing and teammate Impaler both left SUPA HOT CREW. About a month later, on November 9, it was announced that kaSing would be the new support player for Gamers2, after the departure of Rydle.[17] kaSing participated in the Expansion Tournament with Gamers2, who managed to beat Reason Gaming in the seeding game and Team Strix in Round 1. Gamers2 were knocked out in Round 2 after being beaten by n!faculty.

2015 Season[edit]

On the 9th of February, it was announced that KaSing would be joining H2k-Gaming.[18]

The Spring Split itself was relatively successful for kaSing and H2k. After a shaky start, results began to pick up for the team, largely thanks to kaSing's introduction to the roster. kaSing's impressive individual performances throughout the split, particularly on
, helped the team to a 3rd place finish in the regular season. In the Spring Playoffs, kaSing and the team beat Copenhagen Wolves in the quarterfinals, but were beaten in the semifinals in a close-fought series by eventual champions Fnatic. H2k-Gaming went on to pull off a shock victory over SK Gaming in the third-place match, securing themselves 50 Championship Points.

kaSing and the team began to impress from the very start of the Summer Split. H2k jostled for 2nd position with Origen throughout the regular season, with Fnatic way out in 1st place throughout. More impressive performances from kaSing on
ultimately helped the team to yet another 3rd place regular season finish. The Summer Playoffs also went well for kaSing and the team, beating Giants Gaming in the quarterfinals of the tournament. The were beaten in the semifinals by Origen, but went on to beat Unicorns Of Love in the third-place match, securing the team 70 Championship Points, which meant that the team had qualified for the 2015 World Championship as Europe's #2 seed.

At the 2015 World Championship, H2k were seeded into Group C along with SK Telecom T1, EDward Gaming, and wildcard team Bangkok Titans. In one of the only widely-predicted results of the tournament that came to pass, H2k won their games against BKT but lost the rest. kaSing and the team finished the group in 3rd place, meaning they would not advance to the knockout stage of the tournament.

2016 Season[edit]

In November, kaSing left H2k to join Team SoloMid on a trial basis for IEM San Jose.[19] While it was never announced whose decision it was to part ways, after a semifinal finish and loss to Origen, he did not remain with the team and instead returned to Europe, where he joined Team Vitality, a French organization that expended into League of Legends by purchasing Gambit Gaming's LCS slot. With himself, Cabochard, Shook, Nukeduck, and Hjärnan comprising the roster, the team was considered one of the top lineups in the LCS, and they finished the split in third place, behind the surprise first-place G2 Esports and second-place H2k. In the playoffs, however, they were upset by the sixth-place Fnatic and eliminated in the quarterfinals. Shortly later, kaSing left the team.

2017 Season[edit]

After leaving Team Vitality, kaSing announced he would be building a new team to compete in the upcoming EUCS Summer Split with players he scouted from various amateur teams. He would keep the roster a secret until April 2017.

In April, kaSing announced the full roster, with MagiFelix from EURONICS Gaming, Sedrion from Beşiktaş.OH, and two Korean imports MooJin from Dark Wolves and Thal from ZTR Gaming. Apart from kaSing, the other members of the team are relatively unknown, with a handful, including the team’s top laner Kwon “Thal” Hyuk Park, best known for their time in ranked solo queue. Thal achieved first place in the EUW solo back in April.

Red Bulls achieved first place in the 2017 EU Challenger Open Qualifiers and advance to 2017 EUCS Summer Qualifiers. The team was placed in Group A and managed to achieve 2nd place with a 4-1 score and proceed to the finals. In the finals they faced Group B's top seed Team-LDLC and won 3-0 to qualify for EUCS 2017 Summer Split.

The team competed with other well known teams in the EUCS Summer Split such as Giants Gaming, FC Schalke 04, Paris Saint-Germain, and Origen. The team ended the split at 3rd place with a 2-2-1 score with 8 points. They would make it to playoffs and face off against 2nd place team FC Schalke 04. Red Bulls lost the playoff series with a quick 0-3 and failed to qualify for the EU LCS 2018 Spring Promotion. Shortly after the loss, kaSing announced that the team would disband and all players are allowed to look for other opportunities.

2018 Season[edit]

kaSing joined Splyce in December 10, 2017. The new rebuilt roster consists of Odoamne, Xerxe, Nisqy, Kobbe, and kaSing. The team tied 2nd place in the 2018 EU LCS Spring Split with G2 Esports, both having a 11-7 score. Splyce lost the tiebreaker and was placed 3rd seed going into playoffs. The team played Team ROCCAT in the first round and quickly won 3-0, advancing to the second round where they would face G2 Esports once again. Splyce lost the series 1-3. The team later faced Team Vitality in the third-place match and won, earning them 3rd place in the Spring Split.

Splyce placed 6th in the 2018 EU LCS Summer Split with a 9-9 record, barely qualifying for playoffs. They would face FC Schalke 04 in the first round in playoffs and lost the series 2-3, forcing them to compete in the Regional Finals in order to go to Worlds. Splyce played Misfits Gaming in their first round and won the close match 3-2. They would then lose the following round to G2 Esports 2-3, failing to make it to Worlds. Shortly after, kaSing announced he would be leaving the team to join British Organisation Excel Esports.
