The pre-WLC era
Before the WLC existed, Cyrus Washington, an American striker, fought Tun Tun Min three times in Yangon. The bouts were exhibitions — Tun Tun Min's Openweight Golden Belt was not at stake in any of them.
Fight I — 7 December 2014 — Washington wins
The first meeting was on 7 December 2014 at the Air KBZ Aung Lan Championship 2014 in Yangon. Washington knocked Tun Tun Min out in round 3; even after his injury time-out, Tun Tun Min could not continue.
Fight II — 11 April 2015 — Tun Tun Min wins
The rematch, on 11 April 2015 at Thingyan Fight 2015 in the Thuwunna National Indoor Stadium, Yangon, saw Washington knock Tun Tun Min down with a spinning technique. Tun Tun Min recovered during his time-out, knocked Washington down in round 5, and Washington's corner threw in the towel.
Fight III — 20 December 2015 — Tun Tun Min wins
The rubber match, on 20 December 2015 at the Air KBZ Aung Lan Championship 2015 in Yangon, ended with Tun Tun Min striking Washington on the eye socket. After his time-out, Washington declined to continue; the bout was stopped after 71 seconds.
What this series established
Washington took the opening bout by knockout; Tun Tun Min won the next two. As exhibition bouts, none of the three affected the Openweight Golden Belt, which Tun Tun Min continued to hold until he lost it to Dave Leduc in December 2016.
