Round 1- Win O'Reilly
Round 2- Win Gillies- After a good square off, Gillies lands a nice left that stands Taz up and practically knocks him over, a short fight but definitely in Gillies favor.
Round 3- Win Gillies- Gillies basically attacks Taz after Taz got the lebow or stick up in the corner, playing his usual dirty style and Gillies goes off on him.
Round 4- This is one of the trickier fights to call as Taz is doing really well with him and then kicks Gillies and Gillies gets up and lands a massive left while both are being held by the linesman. Gillies clearly didn't like getting kicked and Taz got smashed for it, got knocked on his keister. You could easily argue a draw as a result of that last punch by Gillies but I know homers will say it wasn't fair and shouldn't count or some BS like that but it was a fight and a huge punch landed, knocking Taz down and the fight is over so you could also certainly argue for a TKO in Gillies favor!
Tough to call so I am going with a draw in round 4 to keep it diplomatic.
