The Nationals, looking to bounce back from last season's disappointing finish, had been quiet this offseason -- until Monday. That's when general manager Mike Rizzo announced his entry into the Hot Stove conversation by pulling off a big trade with the Tigers.
Rizzo bolstered his rotation and replaced Dan Haren by acquiring another veteran right-hander, Doug Fister, in exchange for reserve infielder Steve Lombardozzi and young left-handers Ian Krol and Robbie Ray.
The A's were active on both the free-agent and trade fronts. GM Billy Beane brought aboard closer Jim Johnson, sending second baseman Jemile Weeks and a player to be named later to the Orioles. Earlier in the day, Oakland added to its rotation by agreeing to a two-year deal with left-hander Scott Kazmir, who resurrected his career with the Indians last season.
Monday was the last day for teams to tender contracts to their arbitration-eligible players, with the deadline at 11:59 p.m. ET. Any non-tendered player becomes a free agent.
Among the players cut loose were pitchers John Axford of the Cardinals, Andrew Bailey of the Red Sox, Daniel Hudson of the D-backs, Jerome Williams and Tommy Hanson of the Angels, Jeremy Hefner of the Mets and Mitchell Boggs of the Rockies; catcher J.P. Arencibia of the Blue Jays; infielders Mat Gamel of the Cubs, Justin Turner of the Mets, Elliot Johnson and Paul Janish of the Braves, Jayson Nix of the Yankees and Chris Getz of the Royals; and outfielders Sam Fuld of the Rays and Ryan Kalish of the Red Sox.
