Charles' contract was selected by Oakland on Friday.

The move protects the righty from the Rule 5 draft. Charles spent all of 2020 working out at the Athletics' alternate training site. The 24-year-old has yet to advance beyond Double-A but produced a 2.89 ERA in 62.1 innings of relief across three levels in 2019, with his 35.1 percent strikeout rate generally overcoming a 16.2 percent walk rate.
