Barclays Center, Brooklyn - In a back-and-forth title showdown, Detroit's Tony Harrison (28-2, 21 KOs) pulled off the upset to win a narrow unanimous decision over Jermell Charlo (31-1, 15 KOs) and capture the WBC Super Welterweight Championship.

Charlo expressed his disagreement with the judges' decision after the fight.

"You know they took that fight from me," said Charlo. "I was there, pushing the action the whole time. He was moving around just going to the jab, one or two punches. He didn't win that fight."

Harrison was effective with his jab as he attempted to keep the power-punching Charlo at bay. Harrison landed his biggest punch of the fight in round five when a straight left appeared to temporarily stun Charlo.

Charlo was able to land several effective power punches throughout the 12 rounds, including an overhand right late in round five that wobbled Harrison. Round nine saw both men land significant shots, which lead to an exchange where Charlo urged Harrison to keep coming forward.

Harrison was caught off balance in round 11 and again in round 12 by Charlo power punches, but was able to use his movement and hold at key times to survive both rounds. After 12 rounds of action the judges preferred Harrison's jab, movement and counters to the forward-charging power punches of Charlo.

All three judges scored the fight for Harrison, by scores of 116-112 and 115-113 twice. Per CompuBox, Harrison connected on 34 percent of his punches throughout the fight to Charlo's 29 percent clip, while Charlo out landed Harrison 160 to 128, plus a 108 to 71 advantage in power punches landed.

After the fight, Harrison indicated he would be willing to give Charlo a rematch while Charlo immediately stated his intention to get his belt back.

"I'm going to get my belt back," said Charlo. "I still want Jarrett Hurd. I know my brother knows I won that fight. I might have given away a few rounds, but I won that fight."
