Vince Phillips

Vincent Edwards "Vince" Phillips (born July 23, 1963) is an American former professional boxer who competed from 1989 to 2007. He held the IBF junior welterweight title from 1997 to 1999, notably scoring an upset victory against then-undefeated Kostya Tszyu to become champion.
Amateur career.
As an amateur, Phillips won the U.S. National Golden Gloves in 1985, and the U.S. National Championships in 1985 and 1986, all in the lightweight division.
Professional career.
Phillips made his professional debut on February 28, 1989, stopping Octavio Guardado in two rounds. He would win his next 27 fights until losing to Anthony Jones November 18, 1993, due to cuts in the seventh round. On April 12, 1996, Phillips made his first world title challenge by facing WBA welterweight champion Ike Quartey, but was stopped in three rounds. A year later, on May 31, 1997, he scored a major upset by defeating then-unbeaten world champion Kostya Tszyu to win the IBF junior welterweight title, which was named the Upset of the Year by "The Ring" magazine. Phillips made three successful title defenses throughout 1997 and 1998, until a fifth-round stoppage loss to Terron Millett on February 20, 1999. He would fight for another eight years, albeit never again for a world title, and ended his career with a ten-round unanimous decision loss to Alisultan Nadirbegov on May 6, 2007.
