Source: Mussina to retire after 18-year career

As expected, New York Yankees pitcher Mike Mussina has decided to retire, according to a baseball source with knowledge of the situation. Mussina informed the Yankees last week he would give them a decision by the end of this week.

Mussina, who turns 40 next month, spent the last eight seasons with the Yankees after pitching for the Baltimore Orioles for the first 10 years of his career. His 270 wins rank second among all active right-handers, behind only Greg Maddux. In the final start of his career, he pitched six shutout innings against the Boston Red Sox to finish off the first 20-win season of his career.

According to the Elias Sports Bureau, he's just the fifth pitcher since 1900 to win 20 games or more in the final season of his career -- and the first since Sandy Koufax in 1967. He's the only pitcher in that group to win his 20th game in his final start.

The Yankees had indicated they were interested in bringing Mussina back if he wanted to keep pitching. But they had also suggested they might need to wait to see if they could accomplish their goal of signing at least two other free-agent starters this season -- an indication they weren't counting on Mussina to return from the beginning.

His retirement was first reported by Foxsports.com.
