The Cincinnati Reds have traded Ken Griffey, Jr. to the Chicago White Sox in exchange for pitcher Nick Masset and infielder Danny Richar according to Ken Rosenthal at FoxSports.com. Both teams are willing to see if Griffey will accept the trade given that he is a 10-5 player and can refuse any trade.

The Reds have traded Griffey to the White Sox, pending his approval. Griffey will decide Thursday morning whether he will approve the deal, according to a source with knowledge of the situation. It is not known what the Reds would receive in return.

Griffey, as a player with at least 10 years of major-league service, five with the same club, has the right to block any deal. The White Sox attempted to acquire him from the Reds at the trade deadline in 2005, but the trade reportedly was nixed by Reds ownership for financial reasons.

If Griffey agrees to the trade the White Sox will become the third MLB team he has played for. He came up and spent several years with the Seattle Mariners before returning to his childhood home of Cincinnati where injuries curtailed many of his years there. Griffey hit his 600th home run earlier this year and is one of the few players most believe has been clean (without steroids) for his entire career.

MLB’s trading deadline is today for unrestricted trades.
