The Nationals have signed free agent reliever David Goforth to a minor league deal, the team confirmed Saturday. The deal includes an invite to spring training. Goforth, 29, completed his third campaign with the Brewers in 2017. The right-hander lasted just four days in the majors, tossing one scoreless inning before getting reassigned to Triple-A Colorado Springs for the rest of the year. In Triple-A, he produced a 3.98 ERA, 4.3 BB/9 and 6.3 SO/9 in 54 1/3 innings and elected free agency following the conclusion of the season in October.
