Shane Mosley announced his retirement from the ring less than a month after losing to Canelo Alvarez in May 2012. He finished his career with a 46-8 record.
Mosley had a dramatic career, winning his first championship at the age of 26 as a lightweight when he defeated Philip Holiday. While that victory was not a famous triumph, it made Mosley a boxing champion and pushed him into the spotlight.
Mosley was a workmanlike fighter who knew how to take advantage of his opponents' mistakes. He lost some big fights to Floyd Mayweather, Manny Pacquiao, Vernon Forrest and Miguel Cotto, but he also had a number of well-earned and dramatic wins.
Mosley's name was tainted by a performance-enhancing drug scandal (source: New York Daily News), but he was a hard-working and solid fighter.
