José Luis Castillo

Castillo closed the fight strong, outlanding Mayweather 35-20 in the 11th round and totally dominated the 12th.

Punch stats showed Castillo with lopsided totals in every category; punches landed, thrown & power punches landed & thrown and overall connect percentages.

Despite the clear advantages numerically, Castillo’s slow start cost him the fight as he only won 1 of the first 6 rounds.

Judge Jerry Roth and John Keane scored it 115-111, and judge Anek Hongtongkam scored it 116-111, all for Mayweather, a decision that was loudly booed by the crowd.

The HBO announce team loudly voiced its disapproval of the verdict, with unofficial scorer Harold Lederman having Castillo winning 115-111.

Despite the unofficial scorer Harold Lederman scoring the fight for Castillo, most ring side press for the fight scored the fight for Mayweather, including unofficial scorers for Ring Magazine, ESPN, and the Associated Press all scoring the fight for Mayweather.

Ultimately the fight was close enough to the Mayweather team that a rematch was signed.

After Mayweather's successful shoulder surgery, Castillo re-matched with Mayweather.

Mayweather used his quick footwork, combinations and his jab specialty to coast to another unanimous decision victory, this time with all analysts in agreement, including Harold Lederman.

The smaller Mayweather was again outweighed by Castillo on the night of the fight, as Castillo weighed 147 and Mayweather weighed 138.

José Luis Castillo (born December 14, 1973) is a Mexican former professional boxer who competed from 1990 to 2014.

Generally considered one of the best lightweights of his era, he is a two-time world champion at that weight, having held the WBC title twice, from 2000 to 2002 and 2004 to 2005; and the Ring magazine and lineal titles from 2004 to 2005.

In 2000, having two straight wins over Jorge Paez and Steve Quinonez, Castillo challenged WBC lightweight titleholder and Ring No. 1 ranked Lightweight Stevie Johnston.

Heavily favored as underdog, Castillo was slated to lose.

Instead, Castillo scored the Ring Magazine Upset of the Year, defeating Johnston by a majority decision, in what was a very close fight.

Three months later, they fought to a draw, memorable because miscalculation adding the scores led to an original announcement of Johnston regaining his title, which Castillo learned about when Johnston showed up in his dressing room to return the strap.

After fighting Johnston, Castillo defended his title against Ring Top 10 Lightweight, César Bazán.

Castillo defeated Bazan by 6th-round TKO, dropping Bazan in the 5th and 6th rounds.

In his first bout with undefeated American junior lightweight champion Floyd Mayweather Jr.., Castillo started slow but gradually lured the flashy boxer into a toe to toe battle.

Castillo had great success in the middle rounds, when he cut off the ring and used his strength to try wearing down Mayweather.

As the fight progressed, Castillo's power and pressure seemed to turn the fight in his favor, having tremendous success with body punching while Mayweather became more stationary, allowing the stronger Castillo to do significant work.

On June 5, 2004, Castillo regained the Lightweight title and won the vacant Ring Lightweight title by defeating Ring No. 1 ranked Lightweight, Juan Lazcano.

Castillo won the fight by unanimous decision, by the scores of 117-111, 116-112, and 115-113.

In Castillo's first title defense, he fought former Super Featherweight and future Lightweight champion, Joel Casamayor.

In what was a very close fight, Castillo was awarded the close and controversial split decision.

The scores were 116-112 and 117-111 for Castillo, and 115-113 for Casamayor.

Castillo is best known for his 2005 fight against Diego Corrales, for which he received Fight of the Year awards by both The Ring and the Boxing Writers Association of America, as well as his much-debated first fight with Floyd Mayweather Jr...

On May 7, 2005, Castillo fought WBO Lightweight champion and Ring No. 1 ranked Lightweight, Diego Corrales.

Corrales defeated José Luis Castillo for the WBC lightweight title via TKO in the tenth round.

The fight is almost universally regarded as the best fight of 2005.

Both men stood in front of each other, battering each other with hard combinations and power punches throughout the entire fight.

Finally, in the tenth round, Castillo knocked Corrales down.

Seconds later, Castillo knocked Corrales down again.

Once on the ground, Corrales managed to beat the count, and, after a point was taken away for excessive spitting out of the mouthpiece, Corrales connected with a punch that Castillo later called "a perfect right hand."

Corrales then trapped Castillo against the ropes and landed numerous punches, causing the referee, Tony Weeks, to stop the fight.

A rematch between Corrales and Castillo occurred on October 8, 2005.

On the day before the fight, Castillo weighed-in 3½ lb over the 135 lb lightweight limit.

Since Castillo did not make the weight, the fight became a non-title bout.

The two fighters continued with the same fighting style that they had used in the first fight, trading inside punches throughout the first three rounds.

Castillo's next fight was a title defense against Ring Top 10 Lightweight, Julio Díaz, which Castillo won by TKO in the 10th round.
