More boxing fans than usual tuned in Saturday night for a highly anticipated battle between Mexican warriors.

Nielsen Media Research released figures Tuesday that indicated a peak audience of 884,000 watched ESPN’s telecast of the Emanuel Navarrete-Oscar Valdez main event from Desert Diamond Arena in Glendale, Arizona. The average audience for a 12-round, 130-pound title bout Navarrete won unanimously was 808,000, according to Nielsen.

The numbers Nielsen reports are based only on those who watched on ESPN’s linear channel. Nielsen doesn’t track streaming viewership on ESPN+ and ESPN doesn’t divulge those sizable portions of viewership totals publicly.

The taller, awkward Navarrete (38-1, 31 KOs) retained the WBO junior lightweight title he won by stopping Australia’s Liam Wilson (11-2, 7 KOs) in the ninth round of his previous fight. Navarrete got up from a fourth-round knockdown to drop and stop Wilson in the ninth round February 3 at Desert Diamond Arena.

Six months later, Navarrete fought through an injury to his right hand during the second half of their fan-friendly fight to win a unanimous decision over Valdez. He also landed left hands routinely enough to leave Valdez’s right eye swollen shut.

Though their fight was competitive, judges Lisa Giampa (119-109) and Chris Wilson (118-110) scored 11 and 10 rounds, respectively, for Navarrete. Judge Chris Wilson scored eight rounds for Navarette, who won 116-112 on his card.

Valdez, 32, lost a 12-round unanimous decision for the second time in his past three fights.

Shakur Stevenson (20-0, 10 KOs) dominated Valdez in their 130-pound title unification fight in April 2022 at MGM Grand Garden Arena in Las Vegas. Stevenson, a two-weight world champion from Newark, New Jersey, dropped Valdez during the sixth round and won by scores of 118-109, 118-109 and 117-110.

Mexican junior welterweight prospect Lindolfo Delgado defeated countryman Jair Valtierra by unanimous decision in ESPN’s 10-round co-feature Saturday night. Delgado (18-0, 13 KOs) beat Valtierra (16-3, 8 KOs) by scores of 99-91, 99-91 and 98-92.

The network’s tripleheader began with heavyweight prospect Richard Torrez Jr.’s first-round knockout of Willie Lake Jr. Torrez (6-0, 6 KOs), of Tulare, California, dropped Indianapolis’ Lake (11-4-2, 3 KOs) with a counter right hook and later landed power punches that made referee Robert Hoyle stop their scheduled six-rounder only 82 seconds into it.
