On this card alone, the co-main event is between the 2nd-ranked SW in the world (champion Saruta) and the 3rd-ranked SW in Pacio. Saruta might be the physically-strongest guy in the entire division and Pacio is a finisher with 14 of his 16 wins coming by submission or KO (very impressive for the lower divisions). You can watch any of their Youtube fights and you'll see they're extremely high-level and legit world-class fighters. For quick and exciting moments, though, here's Saruta getting a one-punch KO over a top-20 FLW in 2012 I think: And here's a green Pacio getting a submission over a current top-15 SW in a fun back-and-forth quick grappling battle: Interestingly, Saruta's more of the grappler and Pacio's more of the striker. If you like entertaining fights, the Kelly brothers Edward and Eric are both fighters to look out for. Even when they lose the fights are great, and Eric Kelly's heart means he's never out of a fight while Edward's knockouts are pretty good. Xie Bin's a very tall BW prospect on a 6-fight winning streak in ONE, and his opponent has more KO power than anyone he's faced in his career. If you want a ONE fighter in general, Yoshiki Nakahara's a bandwagon you'll wanna jump on before everyone else gets on it. He's on an 8-fight winning streak and 9-1 over his last 10, having avenged the loss to Pancrase ranker Kyosuke Yokoyama on his current stretch. He's beaten a lotta strong guys on the Japanese circuit, too. He's still green, but he's got more potential than any FW that's come out of Pancrase in a long time.
