Jump will be called up from Triple-A Las Vegas to make his major-league debut Tuesday with a start against the Mariners, Martin Gallegos of MLB.com reports.
Reports had surfaced earlier Tuesday indicating that Jump was on his way to the big leagues, and now there's a specific date attached to his debut. Tuesday's previously scheduled starter, Luis Severino, will be pushed back as a result of Jump's addition to the rotation. Jump has collected a 4.50 ERA and 56:20 K:BB over 38 innings with Las Vegas this season and has spun 11 shutout frames with a 15:1 K:BB in his last two starts.
