The Orioles announced Thursday that they've signed four players -- infielders Ivan De Jesus Jr. and Chris Marrero, outfielder Xavier Paul and right-hander Fabio Castillo -- to minor league deals and invited all four to spring training.
Originally signed out of the Dominican Republic by the Rangers, Castillo is 33-37 with a 4.63 ERA in 251 minor league games (37 starts) in his career. Last year, he was a combined 6-7 with a 5.34 ERA in 37 games (seven starts) at Double-A and Triple-A.
Marrero, a 25-year-old first-round pick of the Washington Nationals in 2006, has hit .232 in 133 plate appearances in parts of two seasons in the major leagues.
De Jesus Jr., 26, is a 2005 second-round pick of the Dodgers. Primarily a second baseman who can also play third base and shortstop, he has batted .205 in 80 plate appearances in the majors in parts of two seasons for the Dodgers and Boston Red Sox.
