Castro signed a minor league contract with Oakland on Thursday that includes an invite to spring training, CSN Bay Area reports.

Castro put together a solid showing at Triple-A Albuquerque in 2016, where he was one of the club's most-used relievers, as he threw for a 3.38 ERA and 1.20 WHIP over 53.1 innings (50 games). He also posted a 25.8 percent K-rate, which is well above his career average of 20 percent, and managed to walk batters at a career-low rate of 5.3 percent.
