Brandun Lee made the most of his exposure Friday night on Showtime.

In his first televised fight, the 20-year-old prospect drilled Milton Arauz with a right hand that knocked him out in the second round of their scheduled eight-round welterweight bout in Midland, Texas. Lee’s crushing right hand sent Arauz to the canvas just before the second round ended in the opener of a “ShoBox: The New Generation” tripleheader.

Arauz attempted to get up, but he stumbled. Referee Daniel Sandoval quickly realized Arauz shouldn’t continue and halted their fight with one second to go in the second round.

Lee, of La Quinta, California, remained undefeated (17-0) and recorded his 15th knockout. The 27-year-old Arauz (10-2-1, 5 KOs), of Jinotega, Nicaragua, lost by knockout for the first time as a pro.

Before dropping Arauz with the shot that ended their fight, an overhand right by Lee knocked out Arauz’s mouthpiece with just under a minute remaining in the second round.

A left hook by Lee wobbled Arauz and backed him into the ropes with about 40 seconds to go in the first round. Arauz withstood Lee’s ensuing onslaught and reached the end of the opening round.

Lee had knocked out each of his six previous opponents in the first round.

Earlier Friday night, welterweight prospect Vito Mielnicki knocked out Caleb Bailey in the first round of a four-round bout.

The 17-year-old Mielnicki (2-0, 2 KOs) knocked down Bailey twice in the opening round. Their fight was stopped 50 seconds into it, once Bailey (0-2) went down for the second time.

Mielnicki, of Roseland, New Jersey, recently began his senior year at West Essex High School. Bailey, of Salisbury, North Carolina, has been stopped in each of his two professional fights.

Highlights from Mielnicki’s victory aired on Showtime following Lee’s win.
