Petwason was a really big fighter back before 2018. He's currently on a *really* bad streak with 3 losses in a row to Extra and 1 to Yamin. 2-6-1 since the start of 2018. Before that, he was 2017 Rajadamnern Stadium Fighter of the Year and I think made the shortlist for FOTY.
In 2017, he fought from apparently 116 (only once, usually lowest at 121) to 130. Fought the whole year in 3 divisions with wins over Mongkolchai, Petdam, Superbank and Kaonar, drew Tawanchai. He went 8-1-1 that year.
He hasn't disappeared, he just took a break after his 3 losses to Extra then Covid hit, prob in bad shape rn but he('s young (under 21), can still make a comeback.
