Freeman appeared in just eight games over the last two seasons while recovering from Tommy John surgery -- seven of those with the Nationals last year -- but when healthy, he's been a solid option with a 3.58 ERA over 271 career games. He stands a good chance of making the Royals if he shows quality stuff in the Cactus League.  

Freeman cleared outright waivers before opting to explore the open market. The 33-year-old underwent Tommy John surgery a few weeks ago and will likely miss the entire 2021 season.

Guerra chose to test the open market after clearing outright waivers. The 34-year-old posted a 4.02 ERA over 14 relief appearances this season before suffering a left hamstring strain in early September.

It's the second time that Freeman has had the procedure done. Martinez noted that his recovery is going well. He's expected to miss most of -- if not all -- of the 2021 season while recovering.
