Tengnueng Sitjaesairoong

Tengnueng Sitjaesairoong (Thai: เต็งหนึ่ง ศิษย์เจ๊สายรุ้ง; born October 6, 1992), formerly known as Super-X Por. Petchnamchai, is a Thai Muay Thai fighter from the Nakhon Sawan province of Thailand. He is a 2014 King's Cup tournament winner.

Tengnueng is known for his tendency to deliver knockouts early in his fights, usually within the first round.

He has achieved fame on THAI FIGHT, a Thai promotion which hosts Muay Thai events all over Thailand and around the world. Fighting in a larger weight class than most Thai fighters, Tengnueng has become a fan favorite in THAI FIGHT and is a main event staple. He is a two-time THAI FIGHT Champion.

As of February 2020, Tengnueng is ranked the No. 2 light heavyweight by WBC Muaythai.

Tengnueng Sitjaesairoong was born Ekkapan Somboonsab on October 6, 1992 in Nakhon Sawan, Thailand.

He started practicing Muay Thai at the age of 6, receiving training from his father, a former Muay Thai fighter. In his early days, he would partake in 3-round fights.

Tengnueng first joined the Meenayothin Gym but later moved to the Rachanon Gym to kickstart his Muay Thai career. He began fighting under the ring name of Super-X Por. Petchnamchai.

Early on, his professional career got off to a rough start as he lost the majority of his fights, all by decision. During this time, he usually fought at the Siam Omnoi Stadium and the prestigious Rajadamnern Stadium.

On September 19, 2012, Tengnueng made his first appearance on THAI FIGHT, facing Abdallah Mabel at THAI FIGHT Lyon. However, he wound up losing by 2nd-round TKO.

After a falling out with the head of the Rachanon Gym, he took some time away from Muay Thai. Tengnueng later returned and resumed training with the Dechrat Gym in 2014, with whom he has been training with ever since, and began fighting under his current ring name of Tengnueng Sitjaesairoong.

His style of Muay Thai is regarded as 'Muay Mat', emphasizing powerful punches and the occasional lethal low kick.

2014

In his comeback, Tengnueng Sitjaesairoong went on to participate in the 2014 Omnoi Stadium Weber 154lbs Muay Thai Tournament at Omnoi Stadium.

He then defeated Gaëtan Dambo by decision at THAI FIGHT Samui 2015 on May 2, 2015.

Next, he faced Alex Oller at THAI FIGHT Shaolin in China on July 18, 2015, where he proceeded to deliver a 1st-round knockout, the first of many.

On August 22, 2015, he defeated Alka Matewa of Belgium by unanimous decision at THAI FIGHT Narathiwat.

Tengnueng resumed his habit of finishing opponents and began a long streak of knockout victories as he proceeded to beat Aleksei Dodonov via 2nd-round TKO at THAI FIGHT Moscow on September 17, 2015.

On October 24, 2015, Tengnueng defeated the Lithuanian Sigitas Gaizauskas by 2nd-round KO at THAI FIGHT Vietnam.

At THAI FIGHT London, on September 11, 2016, he beat Sam Gough by 1st-round TKO with a low kick.

On October 5, 2016, Tengnueng defeated Erik Massion of Germany by 1st-round KO at THAI FIGHT Emei.

He would then go on an uncharacteristic three-fight losing streak, including a decision loss to Hamza Ngoto at THAI FIGHT Paris on April 8, 2017. This marked his first loss in THAI FIGHT since September 19, 2012.

2019

After a period of inactivity for most of 2017 and 2018, in which he fought once each year, Tengnueng later returned to THAI FIGHT in 2019 on February 23, 2019 at THAI FIGHT Phuket 2019. This time, he had noticeably put on weight and fought at a heavier 80 kg (176 lbs), as opposed to his previous fighting weights of 70-75 kg (154-165 lbs). His first opponent of the year was Russia's Mike Vetrila, whom he knocked out in the 3rd round, keeping his streak of KO wins alive at 12.

On March 30, 2019, he defeated Evgenii Afanasev at THAI FIGHT Mueang Khon 2019 by 2nd-round KO.

Tengnueng seemed to return to his previous form, despite his weight gain, when he delivered a 1st-round KO of Simon Maait of Australia at THAI FIGHT Samui 2019 on April 27, 2019.

However, this was not to last as his performance was called into question when he faced Mohammad Hossein Doroudian of Iran at THAI FIGHT Betong 2019 on June 29, 2019. After uncharacteristically getting knocked down early in the 1st round, Tengnueng seemed hesitant to engage but was able to inflict his own damage in much of the 2nd round. However, the judges deemed the fight to be even after 3 rounds and declared the match a draw, requiring a 4th round to be fought. Both Tengnueng and Doroudian, obviously gassed, were reluctant to engage but the Thai was declared the winner by extra-round decision. This fight ultimately ended Tengnueng's streak of wins by KO at 14.

On August 24, 2019, Tengnueng defeated Aboofazel Goodarzi by 1st-round KO at THAI FIGHT Kham Chanod 2019.

Tengnueng was eventually booked for a rematch with Mohammad Hossein Doroudian at THAI FIGHT Bangsaen 2019 on October 26, 2019. This time around, Tengnueng captured the 1st-round KO victory with a series of high kicks that gradually wore down Doroudian's arms.

On November 23, 2019, Tengnueng faced Shahram Delavar at THAI FIGHT Mae Sot 2019. While he dominated the entire 3 rounds of the fight, Tengnueng was unable to finish off Delavar and ended up getting the win by decision.

On December 21, 2019, at THAI FIGHT: Thai Fest in Patong, Tengnueng faced perhaps one of his most decorated and experienced opponents in the USA's Cyrus Washington. Washington was perhaps best known for his trilogy of lethwei fights with the Burmese lethwei world champion Tun Tun Min. While Washington was older and slower, he was able to avoid getting knocked out by Tengnueng and the fight eventually went the full 3 rounds. With Tengnueng landing more clear shots, he took the decision victory and was crowned the 2019 THAI FIGHT Light Cruiserweight (81kg) Champion.
