Castro, a Venezuela native, has appeared in 450 major league games over the last six years. He spent the first five seasons with the Tigers. Castro hit for high averages, but a lack of walks and power production left him as a slightly below-average offensive player overall. He ran a .284/.309/.377 slash line in more than 1200 plate appearances with Detroit before being non-tendered.
The Rockies added Castro on a minor league pact last offseason. He made the team out of Spring Training and spent the entire year in Colorado. Despite playing his home games at Coors Field, Castro didn’t maintain the offense he had for the Tigers. He hit .252/.275/.314 with one homer in 99 games. Colorado cut him loose at the end of the season.
Castro has played every position aside from catcher in his major league career. While there’s some value in that willingness to bounce around, he hasn’t been a great fit at any position. Public metrics have graded him as a below-average defender at every spot, with particularly poor grades for his work on the left side of the infield.
