Brian Norman Jr. vs. Jin Sasaki Fight Recap

Brian Norman Jr. (28-0, 22 KOs, 2 NC) scored a brutal knockout of Jin Sasaki (19-2-1, 17 KOs) to remain a welterweight world champion.

The official time of stoppage for their bout was 0:46 of round five. With the victory, Norman remains the WBO welterweight champion. This was his second title defence. Initially an interim titleholder following his win over Giovani Santillan, he was promoted to full titlist after Terence Crawford moved up to super welterweight.

Less than a minute into the opening round, Sasaki was dropped by a counter left hook to the head. Though he quickly got up, Norman soon scored another knockdown after landing several hooks. Sasaki attempted to fight back by swinging hard shots of his own, but as the fight progressed he wilted from the power punches he was taking.

Norman was simply faster, more accurate and more powerful than his opponent. He was able to walk through whatever came his way. The American continued to break down his opponent with each round. The welterweight world title fight was nearing its end.

A left hook to the chin from Norman secured the knockout win for him. It was a brutal shot that will definitely be a contender for knockout of the year. Sasaki hit the canvas hard and the fight was immediately waved off. The Japanese fighter remained unconscious for a considerable amount of time, requiring a stretcher in order to leave the ring.

OUT COLD!!!

Cristian Araneta vs. Thanongsak Simsri Fight Recap

Thanongsak Simsri (39-1, 34 KOs) overcame an early knockdown to defeat Cristian Araneta (25-3, 20 KOs) via split decision.

While one judge scored it 114-113 for Araneta, the other two had it 116-111 and 115-112 for Simsri. With the victory, the boxer from Thailand is now the IBF light flyweight world champion. Masamichi Yabuki was the previous titleholder, but he elected to vacate the belt after winning a title at flyweight.

After an opening round spent figuring each other out, both men opened up in the second. It was Simsri who had success initially, sitting down on punches and landing hard shots to the head and body. By the end of the round two, Araneta was sporting a cut above the left eyebrow.

With roughly 30 seconds to go in the third, Araneta landed a left hook to the head that sent Simsri to the canvas. The Thai fighter got up, however, and continued to trade with his opponent. Simsri was also sporting a cut over his left eye by the end of round three. While Araneta’s left hand was dangerous for the entirety of the fight, Simsri’s greater activity was winning him the rounds.

In the second half of the contest, Araneta pressed forward as he looked for an opportunity to land his left hand. Simsri was still the more active of the two, however, while also being more defensively responsible. A lack of activity proved to be the undoing of Araneta as two of the judges saw his opponent as the victor after 12 rounds. Simsri was simply the busier of the two and that helped him claim his first ever world title.
