On Saturday night, the MGM Grand Garden Arena in Las Vegas, Nevada played host to the Showtime boxing pay-per-view which was headlined by a super middleweight bout between Mexican star Saul “Canelo” Alvarez and Erislandy Lara.

Before the pay-per-view got underway, we were treated to some undercard bouts that included a WBO bantamweight championship bout between current title holder Tomoki Kameda (29-0) and former champion Pungluang Singyu (43-1).

Adding an intriguing story line to the WBO bantamweight title bout was the fact that Kameda won the belt by defeating Paulus Ambunda of Namibia, who had previously defeated Singyu for the title.

Singyu buckled Kameda in the fourth-round and went in for the kill. Mixing in some body shots and punches to the head, Singyu appeared to have Kameda on the ropes, but Kameda was able to survive the round.

Kameda came back strong in the fifth round and seemed to get momentum back in his corner by dictating the pace of the bout.

In the seventh round, Kameda landed a vicious shot to the liver that dropped Singyu to the mat and left him unable to answer the bell. Kameda landed a left hook directly to the liver and Singyu was writhing in pain as his body shut down from the devastating blow.

Official time of the stoppage was at 1:35 in Round 7.
