This past Friday's Bellator 258 saw some thrilling fights with results that would have a major impact on several divisions. No result was as big, however, as Sergio Pettis defeating Juan Archuleta to become bantamweight champion in the night's main event. Pettis outworked Archuleta, using speed and counter-striking to neutralize the tricky attacks of the now-former champ.

With the win, Pettis moved into the champion spot at 135 pounds in the Bellator MMA Fighter Rankings while Archuleta fell to No. 1 contender. Pettis also entered the men's pound-for-pound rankings at No. 7.

In the other big result of the night, Anthony "Rumble" Johnson made his Bellator debut against Jose Augusto in the first round of the Light Heavyweight World Grand Prix. Despite suffering a knockdown and nearly being finished in the first round, Johnson scored a brutal knockout in the second round to pick up the victory in his first fight in more than four years.

Queally enters the rankings at No. 6.
