The Nationals obtain Tigers starter Doug Fister for southpaws Ian Krol and Robbie Ray and infielder Steve Lombardozzi. Washington’s acquisition of the 29 year-old right-hander improves the team’s already strong rotation that includes Stephen Strasburg, Jordan Zimmermann, and Gio Gonzalez.

The pitching-rich Tigers send Doug Fister to the Nationals in return for IF Steve Lombardozzi and Ps Ian Krol and Robbie Ray.

The Orioles send closer Jim Johnson, author of back-to-back 50-save seasons, to the Athletics in return for 2B Jemile Weeks. The A’s also sign free agent P Scott Kazmir to a two-year deal worth $22 million, in expectation of losing both starter Bartolo Colon and closer Grant Balfour to free agency. Kazmir’s signing will prove to be a good move, but Johnson will be a complete bust, earning his unconditional release by mid-season.
