Zaromskis was possibly on the verge of losing to Spiritwolf in their previous fight, which was exciting, so I don't know how anyone could quibble about Bellator making this match.
I really doubt Zaromskis will be in the next tourney. He's exciting, but just not that good, and BFC's WW division is super deep at this point. They could hold two tourneys at their prior standard if need be. Zaromskis is where he belongs as an entertaining feature fighter.
This is going to be a loaded event. Amoussou/Baker, 2 LHW semis, Zaromskis/Spiritwolf III, Beast Boy/TBA (might be Sparks), Ben Saunders/Rudy Bears, Raul Amaya/TBA (might be Foster), Radley Martinez/TBA (possibly Jason Carapelucci), etc. I think they're filling it up because of they'll be holding this event in their biggest venue ever and if prospective tourney fighters want work or inclusion then July will be the last chance for most.
