Cubs sent RHP Eduarniel Núñez outright to Triple-A Iowa.
Núñez will stick around with Chicago as organizational relief depth after going unclaimed on waivers following his removal from the club’s 40-man roster earlier this week. The 27-year-old hasn’t pitched in the majors this season after posting a lackluster 7.11 ERA across 12 2/3 innings between the Padres and Athletics last year.
