UFC on ESPN+ 7 on Saturday in St. Petersburg, Russia, produced a series of interesting results. The ageless Alistair Overeem was victorious in the main event, taking big shots from late replacement Aleksei Oleinik and rallying for a first-round TKO win. Islam Makhachev left no doubt he belongs in the lightweight rankings, as he earned a Fight of the Night bonus for his victory over Arman Tsarukyan, his fifth consecutive victory. And the one and only Roxanne Modafferi scored her biggest win in quite some time, defeating Antonina Shevchenko via split decision in a flyweight bout. So where to rank ’em?
