Anthony Chavez couldn’t capitalize on his opportunity on a high-profile undercard Saturday night in Hollywood, Florida.

Chavez settled for a six-round majority draw with Mexican veteran Diuhl Olguin in a junior lightweight fight on the Evander Holyfield-Vitor Belfort undercard at Seminole Hard Rock Hotel & Casino. One judge scored four of the six rounds for Chavez (58-56), but two judges scored three rounds apiece for Chavez and Olguin (57-57, 57-57).

The 25-year-old Chavez (9-1-1, 3 KOs), of San Bernardino, California, is 1-1-1 in his past three fights. Olguin (15-19-5, 10 KOs), of Guadalajara, Mexico, lost each of his three previous bouts.

Chavez caught Olguin with a right hand in the middle minute of the final round, yet Olguin kept coming forward. The younger, fresher fighter simply couldn’t hurt Olguin, who has lost by knockout or technical knockout three times during his 12-year, 39-fight pro career.

Barely a minute into the fourth round, Olguin drilled Chavez with a right to the side of his head.

Chavez caught Olguin with an overhand right with just over a minute remaining in the third round. He blasted Olguin with another hard right when there were 20 seconds left in the third round.

Chavez’s left hook knocked Olguin into the ropes with 1:35 to go in the second round. Chavez appeared to land more clean punches during a competitive first round.

In the first fight Saturday night, Eliezer Silva succeeded in his pro boxing debut.

Silva out-boxed Terry Roscoe in their four-round middleweight match, which Silva won by unanimous decision. All three judges scored Silva a 39-36 winner.

The left-handed Silva, a former kickboxer who is not related to former UFC star Anderson Silva, was the busier, more accurate fighter throughout their bout. Roscoe, of Albany, Georgia, fell to 2-6 (0 KOs).

Silva landed several flush punches during the fourth and final round, but he couldn’t finish off Roscoe, who was dropped during the third round.

Silva’s left to the body landed with just over 50 seconds to go in the fourth round. He followed it with a left hand to Roscoe’s head a few seconds later.

Silva added two straight left hands in a three-second span late in the fourth round.

Silva’s swift right hook dropped Roscoe 39 seconds into the third round. Roscoe reached his feet quickly, though, and made the remainder of the round reasonably competitive.

Silva went to the canvas with 1:52 to go in the second round, but Roscoe pushed him down. Roscoe connected with a short right inside that got Silva’s attention with 30 seconds to go in the second round.

Silva landed a right-left combination that backed Roscoe into the ropes with 1:10 to go in the opening round.
