Nationals signed outfielder Ruben Mateo to a minor league contract and invited him to spring training.

Mateo's experience in Korea didn't go well, as he played in just 34 games for the LG Twins and hit .223. He only turned 28 last week, so there's still some hope he could contribute as a reserve outfielder somewhere down the line. The Nationals will stick him in Triple-A at the start of the year.
