A heavyweight bout between Matt Mitrione (13-5) and Roy Nelson (23-15) headlined Bellator's latest event at the Mohegan Arena this weekend in the second fight in the organization's 2018 Heavyweight Grand Prix bracket.

The main event ended with Mitrione winning by majority decision, with one judge scoring at 28-28 and the other two scoring it 29-28. It was the second such decision of the evening -- a bout on the preliminary card between light heavyweights Jarod Trice and Walter Howard ended with one judge scoring the fight 28-28 and the other two awarding it to Trice by 29-27 (Howard lost a point after accidentally poking Trice in the eye during the second round).

The main card opened with a bout between Tywan Claxton (2-0) and Jose Perez (0-2). Claxton, who leaned toward southpaw strikes, used his elbows to advantage, securing a TKO at 3:39 in the second round due to unanswered strikes.

During the next fight, Vadim Nemkov (9-2) hobbled Liam McGeary (12-3) with repeated lower leg kicks and secured a TKO victory at 4:02 in the third round after the referee waved the fight off. McGeary, renowned for his grappling game, tried to take Nemkov's back during the second round but was limping badly by the third round and appeared to clearly resign the fight before the referee ended it.

Heather Hardy (2-1) and Anna Julaton (2-4), both of whom are preparing for a future boxing match with each other, faced each other next in a women's flyweight fight. Hardy won by unanimous decision. 

Julaton, who resisted a rear naked choke attempt from Hardy in the first round, wound up in her opponent's closed guard a few times during the fight. Hardy reversed her position on the ground during the second round and attempted a leg trianle submission and a rear naked choke.

During a lightweight bout that opened the preliminary card, Patricky "Pitbull" Freire (!9-8) secured a first round TKO of Derek Campos (19-7) at 2:23 in the first round with punching.

Pat Casey (1-0) defeating Tyler Hamilton (1-1) by unanimous decision in a lightweight bout. 

Kastriot Xhema (2-1) punched his way to a first-round TKO at 3:52, defeating Peter Nascimento (0-1) in a 165-pound catchweight bout.

Marcus Surin (5-1) submitted Dean Hancock (3-2) of Danbury, CT with an arm triangle choke at 4:50 in the second round of a lightweight bout. Hancock gradually began more aggressive during the striking that started the first round, at one point unleashing a kicking and punching combination, but the tide shifted in Surin's favor as the fight went to the ground. Surin took Hanock's back twice, eventually securing the choke.

Trice and Howard went back and forth during the fight that followed, with Trice attempting to land powerful single shots and Howard using his reach advantage to throw straight overhand jabs, sometimes switching from orthodox stance to southpaw. Trice attempted a double-leg takedown during the third round but Howard sprawls out of it. Trice eventually brought Howard to the ground, but the latter reversed his position and got up. Trice, clinging to Howard's leg, got him down again and attempted ground-and-pound from the side -- Howard got back to his feet and the fighters exchanged blows again with Trice landing a high straight kick to the face.

Regivaldo Carvalho (5-2) made short work of Tom English (6-9), knocking him out at :17 in the first round a featherweight match.

Mike Kimbel (1-0) of Waterbury, CT scored a TKO victory over fellow Connecticut resident Geoffrey Then (0-2) at 1:03 in the first round of a Bantamweight fight. Kimbel landed a left to Then's Jaw and a right to the side of his head before going to the ground and attempting an arm bar. Kimbel dropped hammerfists on Then before the referee waved the fight off.

Ross Richardson (1-0) defeated fellow lightweight Ron Leon (0-1) by TKO at 1:41 in the second round by dropping bombs from the bully mount while supporting himself with one hand placed on the ground. Richardson was in and out of Leon's guard during the first round, at one point dropping punches and elbows.
