A former Nationals pitcher is returning to D.C.

The Nats have signed left-hander Tommy Milone to a minor league contract, an industry source has confirmed. He will receive an invitation to major league spring training.

Milone, 30, was drafted by the Nats in the 10th round of the 2008 First-Year Player Draft out of Southern California and made his major league debut with the club in 2011, going 1-0 with a 3.81 ERA in five September starts and homering in his major league debut on Sept. 3 against the Mets.

That winter, he was dealt to the A’s along with right-handers A.J. Cole and Brad Peacock and catcher Derek Norris in the trade that brought lefty Gio Gonzalez to Washington.

Since then, Milone has also pitched for the Twins, Brewers and Mets. In 146 major league games, including 126 starts, the soft-tossing southpaw is 45-36 with a 4.37 ERA.
