By all accounts, Ben Henderson vs. Jorge Masvidal was a close, well-contested matchup from start to finish. Ultimately, Henderson won by split decision (47-48, 48-47, 49-46), which was fitting considering all three of those scores were justifiable. Here's a picture of the official scoring from the cageside judges, who only unanimously agreed on the 2nd round: (Via MMA Fighting)

So you can see how pivotal round 5 was, as the judges had it a majority draw after 4, but while judge Mark Craig gave the last round (and therefore the fight) to Masvidal, Barry Foley went the other way to give Henderson his 4th split decision win of his career. Masvidal is 2-3 when there's a split verdict.
There were an incredible 5 split decisions at UFC Fight Night in Seoul, setting a new all-time record for a single event. Mark Craig was the dissenting voice in 4 of those 5 fights.
