# Robert Guerrero

Robert Joseph Guerrero (born March 27, 1983) is an American professional boxer. He has held world championships in two weight classes, including the IBF featherweight title twice between 2006 and 2008, and the IBF junior lightweight title from 2009 to 2010.

## Professional career
### Featherweight
#### Early career

Guerrero is trained by his father Ruben Guerrero, a former amateur champion, who introduced Robert and his five brothers to boxing as youngsters growing up in Gilroy, California. After an impressive amateur career begun at a very young age, Robert turned professional, at the age of 18, on May 22, 2001 with a four-round unanimous decision win against Alejandro Cruz. After several wins and only a single draw later, Guerrero won the WBC NABF Featherweight title against Cesar Figueroa on December 9, 2004. Defending his NABF title twice, Guerrero was seen as a rising prospect, until meeting Gamaliel Diaz in a bout televised on ShoBox, on the Showtime channel, on December 12, 2005. An aggressive Diaz upset Guerrero, winning by split decision and taking the NABF belt in the process.
Guerrero rebounded from his first loss by defeating Sandros Marcos via third-round technical knock-out, setting up a rematch against Diaz, again on Showtime. Guerrero knocked down Diaz in the first round, and eventually knocking out Diaz early in the sixth round. The win set him up to face IBF champion Eric Aiken.

#### Featherweight title

In his first world championship fight on September 2, 2006, Guerrero defeated Eric Aiken by an eighth-round technical knockout in Los Angeles. Guerrero used inside fighting, neutralizing Aiken's power, and eventually making Aiken quit on his stool after the eighth round to earn his first world title belt.

#### Guerrero vs. Salido

Guerrero lost the belt in his next fight in a mandatory defense to Orlando Salido in Las Vegas. Salido dominated the majority of the bout and pulled off an upset decision win with scores of 115–113, 117–111, 118–110. However, Salido would subsequently be stripped of the IBF title after testing positive for steroids, thus vacating the belt; the result of the bout would also be changed to a twelve-round no decision by the Nevada State Athletic Commission.
The IBF subsequently gave Guerrero the shot at the vacant featherweight title, which he won by ninth-round technical knockout in Copenhagen, Denmark on February 23, 2007, against Albanian boxer Spend Abazi.
Guerrero's second defense of his second title was to be against Rocky Juarez (27–3, 19 KOs); however, Juarez chose to meet WBC Super Featherweight Champion Juan Manuel Márquez in a money fight instead. Guerrero's first defense was scheduled to be against Martin Honorio (24–3–1) on November 3, 2007, and was televised on Showtime, on the undercard of the Marquez-Juarez match. Guerrero was unable to attend the final press conference before the match after his wife Casey was diagnosed with leukemia. Guerrero defeated Honorio in a first round knock-out.
On February 29, 2008, Guerrero defeated Jason Litzau via an eighth round knock out. Guerrero then vacated the title to move up in weight.

### Super featherweight
#### Guerrero vs. Yordan

On March 7, 2009, Guerrero fought Daud Yordan in his HBO debut. The fight ended in a second round "no contest" decision after Guerrero suffered a headbutt resulting in a gash above his eye. After the bout Guerrero offered Yordan a rematch, however, Yordan reportedly declined.

#### Guerrero vs. Hinojosa

On June 12, 2009, Guerrero faced Efren Hinojosa (30–5–1). He suffered another deep cut near his left eye from a head-butt in the seventh round, but this time it did not slow his progress as he scored an eighth round TKO victory. After the bout, the media described him as having redeemed himself for his previous lackluster effort.

#### Guerrero vs. Klassen

On August 22, 2009, Guerrero challenged Malcolm Klassen for his IBF Super Featherweight title. Guerrero won the fight by a unanimous decision to claim the world title. The scores were 117–112, 116–112 and 115–113 in his favor.
In February 2010, Guerrero vacated his Featherweight title in order to care for his ailing wife.

### Lightweight
#### Guererro vs. Arrieta

On April 30, 2010, Guerrero moved up to the lightweight division to fight Robert Arrieta (35–15–4). The bout took place at the Tropicana Hotel and Casino in Las Vegas, Nevada, United States. Guerrero won the fight by TKO in the 8th round.
After the bout, Guerrero expressed his interest in fighting Mexican champion Juan Manuel Márquez.

### Light welterweight
#### Guerrero vs. Casamayor

On July 31, 2010, Guerrero moved up to the junior welterweight division and faced Cuban fighter Joel Casamayor on the undercard of the Marquez vs. Diaz pay-per-view at the Mandalay Bay in Las Vegas. Guerrero defeated Casamayor by a 10-round unanimous decision.

### Return to lightweight
#### Guerrero vs. Escobedo

On November 6, 2010, he faced Vicente Escobedo for the vacant WBO Inter-Continental lightweight title. Guerrero knocked Escobedo down in the third and sixth rounds en route to a ten-round unanimous decision.

#### Guerrero vs. Katsidis

On April 9, 2011, Guerrero faced Michael Katsidis for the interim WBA and WBO lightweight titles. Guerrero won the bout with a 12-round unanimous decision. In a post-fight interview when asked about his hometown he said, "It's nice when you're pretty much their biggest thing besides garlic in Gilroy." Guerrero was scheduled to face Marcos Maidana in August for the WBA junior welterweight title, however, he was forced to pull out of the bout after suffering a torn tendon in his rotator cuff. He underwent surgery to repair the injury and was out of the ring for 6 months.

### Welterweight
#### Guerrero vs. Aydin

Guerrero returned to the ring by jumping two weight classes to face unbeaten top 10 welterweight Selcuk Aydin. On July 28, 2012 Guerrero defeated Aydin in San Jose, California by unanimous decision for the interim WBC welterweight title.

#### Guerrero vs. Berto

Guerrero's next fight was against former two-time Welterweight champion Andre Berto (28–1, 22 KO) at the Citizens Bank Business Arena in Ontario, California. Guerrero started off the fight fast, sending Berto to the canvas each of the first two rounds, as well as badly closing Berto's right eye early on. Berto got back into the fight during the middle rounds, landing hard uppercuts and right hands on Guerrero, who took the punches well. Throughout the fight the two traded punches with Berto on the ropes and Guerrero smothering him, while out working him the majority of the time. By the end of the fight, both of Berto's eyes and Guerrero's right eye were closed shut. Guerrero won a unanimous decision by the scores of 116–110 on all three scorecards. Guerrero had a purse of $1 million, while Berto's purse was $1.625 million. In the post fight interview, Guerrero called out pound-for-pound champion Floyd Mayweather saying, "Pretty Boy, let's do it."

#### Guerrero vs. Mayweather

On May 4, 2013 in a fight billed as May Day', Guerrero lost to Floyd Mayweather Jr. (43–0, 26 KOs) in the WBC Welterweight Championship fight by a unanimous decision in front of a 15,880 crowd at the MGM Grand arena, with all judges scoring the fight 117–111 in favor of Mayweather. Guerrero won the first 3 rounds, then Mayweather adjusted back to his defensive style and won from the 4th to 12th round. Mayweather landing a high 60 percent of his power punches, which included 23 of 30 power punches in the eighth round, when Guerrero was cut over his left eye. Throughout the fight, Mayweather landed 195 punches to 113 for Guerrero. Guerrero reportedly earned a career high of $3 million and the fight exceeded 1 million ppv buys.

#### Guerrero vs. Kamegai

Guerrero took off a full year before returning to the ring on June 21, 2014 to fight Japanese boxer Yoshihiro Kamegai. Guererro could hardly open his left eye toward the end of the fight, but scored a unanimous 12-round decision over the tough Kamegai with official scores of 116–112, 117–111, and 117–111, thereby marking a triumphant return to the ring.

#### Guerrero vs. Thurman

On March 7, Guerrero fought in NBC's first episode of their new series, "Premier Boxing Champions" at the MGM Grand in Las Vegas. Guerrero's opponent was undefeated Keith Thurman. Thurman started off the match as the aggressor, throwing many powerful punches. Guerrero was able to withstand Thurman's blows until he was knocked down in the ninth round. Although the fight seemed bleak for Guerrero he was able to fight back, giving an exciting final three rounds in which he became the aggressor and forced Thurman against the ropes. Ultimately, "The Ghost" lost by unanimous decision but Guerrero's determination and strong will to win had the crowd of the MGM Grand chanting his name for the majority of the final round.

#### Guerrero vs. Martinez

On June 6, 2015 Guerrero fought again on NBC as part of the "Premier Boxing Champions" series at StubHub Center, California, against the gritty Aron Martinez (19–4–1, 4 KOs). Martinez proved himself to be an underdog with bite. The action got going in earnest in Round 2, with both fighters working the body hard in some grueling infighting. Martinez continued to press the action in Round 4, scoring a knockdown at the end with hard body shots and then combinations to the head. But the momentum of the fight began to swing back in Guerrero's direction in Round 6, when he fought more from the outside. Both fighters had their moments in the latter half of the fight, but it was Guerrero who was able to control the distance, outland Martinez and pull out a split-decision win in a feisty back-and-forth battle.

#### Guerrero vs. Garcia

On January 23, 2016 Guerrero fought on FOX as part of the "Premier Boxing Champions" series at Staples Center, California, against the undefeated Danny Garcia (31–0–0, 18 KO) for the vacant WBC Welterweight Championship. The match was ruled a unanimous decision in favor of Garcia with all three judges scoring the bout 116–112, despite fighting on near-equal terms. Guerrero started off impressive, but became less effective late in the fight falling to a 3rd career defeat in a welterweight title fight. Garcia landed 163 of 496 thrown (33%), whilst Guerrero landed 108 of 436 punches thrown (25%).

#### Guerrero vs. Peralta

Guerrero's next fight was announced on July 16, to take place at the Honda Center in Anaheim against Argentine boxer David Emanuel Peralta (25–2–1, 14 KOs) on August 27.

On May 23, 2017 it was announced that Guerrero would fight at the renovated Nassau Coliseum in Uniondale, New York against undefeated former WBC lightweight champion Omar Figueroa Jr. (26–0–1, 18 KOs) on July 15, 2017.

According to Nielsen Media, the fight peaked at 1,039,000 viewers on Fox. The whole show averaged 886,000 viewers.

### Retirement

A couple of days following his first stoppage loss, Guerrero announced his retirement from professional boxing after 16 years. Guerrero had been on a decline, since losing to Floyd Mayweather in 2013. He had only won two of his last six fights. Guerrero said in a statement,
   "First, I want to thank God for allowing me to have a wonderful career. I'm a kid from a small town in Gilroy, California, who made it to the mountain top of the boxing world. When I was a young kid growing up, I always believed in myself, but never in my wildest dreams would I have imagined a small-town kid like myself, would be fighting in front of millions of fans." "I was blessed to win multiple world titles in four-divisions. A boxer's career is a long and tough road. Many tears were shed, lots of blood, and tons of sweat. Many miles were traveled, thousands of rounds sparred, none were easy and nothing was ever given to me. I earned everything I got the old fashion way. I never ducked anyone and fought the best fighters in the world. I fought my way through every obstacle to make sure my fans enjoyed every second, of every round, of my fights."
In the statement, he also thanked advisor Al Haymon and praised him as "the most special man" he ever met in his boxing career. He ended his career with 33 wins out of 42 fights, including 18 wins coming inside the distance.

Guerrero was scheduled to fight 27-year-old Hungarian boxer Adam Mate (28–12, 21 KOs) in a 10-round welterweight bout. For the comeback, Guerrero was guaranteed a $25,000 purse.
