The generally accepted spelling is Byung-Hyun Kim. I suppose that the translation could be spelled in different ways. He did well in 2000 and had an awesome regular season in 2001, but almost blew the 2001 World Series for them. Then he had a great year in 2002. In 2003 they made him a starter, but he was traded to the Boston Red Sox and went back to being a closer. Before the start of the 2005 season, he was traded to Colorado. Nowadays he's pitching in South Korea.
The point is that this case would be like subletting your apartment to somebody who claimed that his name was Dennis Eckersley or Rollie Fingers.
Or some guy registering to vote who claimed that his name was Troy Aikman. (Hat tip to ACORN.)
When somebody uses the name of a thoroughly famous athlete like that, you know you’re being ripped off.
