Porter kept his undefeated record intact, improving to 23-0-1 as he took the fight to Alexander to win on scores of 115-113, 116-112, 116-112.

"We worked hard and it came through in the ring," Porter said. "We made it look easy."

The 26-year-old Porter connected on several hard shots in rounds three and four against the fellow American, and impressed the judges with his consistent work ethic.

Porter was making the first title shot of his career at the Barclays Center arena.

Alexander won the IBF title by beating Randall Bailey in a 12-round bout on October 2012.

Alexander said he lost his focus and couldn't take advantage of Porter's weaknesses.

"I am disappointed," Alexander said. "I didn't follow the game plan as much as I should have.

"He was rushing in and I didn't capitalize on that."

In the other world title fight on the card, Sakio Bika retained his World Boxing Council super middleweight belt with a twelve round draw against Anthony Dirrell.

The judges scored the fight 114-112 Bika, 116-110 Dirrell while one judge had it 113-113.

The Sydney, Australia-based Bika is now 32-5-4 while Dirrell fought to the second draw of career to move to 26-0-2 with 22 knockouts. 

Dirrell dropped Bika in the fifth round but Bika came back and stunned the challenger in the next round.

Bika, who had a point deducted for a low blow in round eleven, was making the first defence of his WBC title.

In a non-title fight between Brooklyn hometown heroes, former two-time world champ Paulie Malignaggi scored a unanimous decision over fellow American Zab Judah.

Malignaggi won the welterweight fight between the ex-world champions on all three judges scorecards, 116-111, 117-110, 117-110.

Judah, who was cut over the left eye in round three, was credited with a knockdown in round two.
