After that Hatton has won many significant welterweight competitions, including the WBA title, and has beaten some of the best boxers in the world. In the MGM Grand Garden Arena in Las Vegas, December 2007 he fought against Floyd Mayweather in the so called one of the biggest fights in the history of the sport where Mayweather defeated Hatton by TKO in the tenth round. His next match was against Juan Lazcano on 24 May 2008, Hatton beat Mexican Juan Lazcano in front of his home crowd of 55,000 by unanimous decision with scores of 120-110, 120-108 and 118-110. The comments after the match were that Hatton did well while boxing and he controlled the range.

On 22 November Hatton fought Paulie Malignaggi at the MGM Grand, Las Vegas where Hatton dominated for all of the fight and defeated Malignaggi by 11th-round with TKO.
On 2 May 2009 again at the MGM Grand in Las Vegas Hatton met in the ring Manny Pacquiao at light welterweight but he was defeated in the second round by a KO.
Hatton fought Manny Pacquiao. The fight was the sixth weight category Pacquiao has fought at, and is the weight at which Hatton was previously undefeated.[32] Pacquiao won, after knocking Hatton down twice in the first round. After the last match Hatton has put his career on pause but in June 2010 he stated: “Boxing started off as a habit and it ended up giving me some money and making me a little bit of a better person. But I don’t think I will have a fight again. But you can never say never as I have not announced officially that I won’t be boxing. At the moment I don’t have any fire in the belly for a fight or to get myself to a gym. But it has been only 13 months and I am only 31, so never count me out. “

His first true achievement – becoming a world heavyweight champion came in 1962 by beating Floyd Patterson. In 1963 he defeated Patterson again with a knock-out in the first round. In 1964 Liston fought against Cassius Clay but he refused to come out for the second round because of shoulder injury and the winner of the mach was Clay. Liston was accused of throwing the match. In 1965 after his rematch with Ali, where he lost in the first round there were made similar accusations and some even claimed that Liston was not actually hit by the winning punch of Ali.

In 1969 after a series of wins Liston had another attempt at the heavyweight title but that ended with being knocked out by Leotis Martin. He won his last fight in 1970 against Chuck Wepner by a knock out. After a year his wife found his body in their home in Las Vegas and although his death still remains a mystery, some believe that he was a victim of a murder.

During the 1980s Tyson defeated a string of heavyweight champions and in 1988 he was crowned world heavyweight champion after dethroning Leon Spinks. He remained undefeated for couple of years until his fight against James “Buster” Douglas in 1990, in Tokyo.

Tyson was as much dangerous in the ring, as outside of it. In 1992 he was sent to prison for raping an American beauty pageant contestant. After getting out of prison in 1995 he staged a series of ‘comeback fights’ until he lost in a boxing match against Evander Holyfield. Two years later, Holyfield and Tyson met again in the ring. This was Tyson’s most discussed fight because after receiving what he saw as intentional head butts from Holyfield, he bit off a portion of Holyfield’s ear. After his last win in 2003 against Clifford Etienne (49 seconds into round one), he was named 16th on a list of a hundred greatest punchers of all time. Tyson continue with losing three fights before he finally retired in 2005.

In 1965 he became a professional boxer and it took him only 5 years to pick up his first heavyweight title after winning against Jimmy Ellis. There were many challengers for the title, starting with Muhammad Ali who in 1971 won in the match known as the ‘Fight of the Century’. No matter the loss he manages to respond in the rematch with a victory, becoming the first fighter to beat Ali in his professional boxing career.

Very much Frazier’s career has been defined by his fights with Ali and this culminated in two matches in 1974 and in 1975, respectively. Unfortunately, Frazier lost both matches but in the second game in 1975 ‘Thrilla in Manila’ one can see how well-suited they were. That was one of the closest meetings in the history of box. The coach of Frazier refused to let him back on the ring for the last round, because both men were fighting in extreme conditions. After losing to George Foreman in the sixth round in 1976, Joe Frazier retired but his rivalry with Ali continued and Frazier provoked Ali any time he could.

However, this was not the end of Foreman who continued boxing and winning. His durability as a boxer was remarkable and in 1994 at the age of 45, he stunned world-wide boxing fans by defeating in the tenth round Michael Moorer and became for the second time a heavyweight champion. He retired from boxing at last in 1998 and in 2003 he was nominated to the International Boxing Hall of Fame and named by Ring Magazine as the 9th greatest boxer of all time.

In 1942 Rocky joined the army, after which he became a professional boxer. Rocky Graziano fought his first title fight in 1946 against middleweight champion Tony Zale and even though Zale kept his title it was a very close game. In 1947 Graziano returned for a rematch and he became the middleweight champion of the world by dethroning Zale. The next year Zale defeated Rocky again but Rocky responded with a series of wins. The challengers continued to come and in 1948, Sugar Ray Robinson took his title. Even though Rocky lost the fight, Robinson claimed that he wasn’t stung like that by another boxer. He retired after losing his next boxing match to Chuck Davey. At Rocky’s funeral in 1990 Vito Antuofermo said that Rocky was “tough, could hit like a mule and had all the guts in the world.”

Ali became a hero thanks to a series of famous contents. For instance, in 1970, he played the named at the time ‘the fight of the century’ against the undefeated in the ring champion Joe Frazier. Ali played against Frazier and he endured the exhausting 14 rounds before in the 15th round Frazier took the title. These two players met again in 1974, in New York where Ali won in a 12-round undisputed decision. He regained his heavyweight title on October 30, 1974 in a match called ‘the Rumble in the Jungle’ against George Foreman. Ali continue with his great fights and a year later, he touched gloves for the third and final time in Quezon City with Frazier in the so-called ‘Thriller in Manila’, where he took the fight in the final round under outstandingly hard conditions. Ali described the boxing match as “the closest thing to death” that he had ever experienced.

In 1978 Ali earned his third and last heavyweight crown when he dethroned Leon Spinks – but the triumph was short-lived, because Ali moved out of the boxing spotlight. In 1982 after being diagnosed with Parkinsons, Ali retired permanently, but in 1999 he was crowned by the BBC as the sportsman of the century. He is well known as an incredible pound-for-pound boxer, with extreme performance against boxers of a similar weight. Together with his legendary fighting ability, Ali was travelling all over the world and fighting for human rights as well.
