"He'll be an option," Gibson said of Skaggs. "We'll get through these next couple of days. We may keep Delgado. It just depends on what goes on."
By bringing up Delgado now, the D-backs give themselves an extra arm in the bullpen through Monday. The club could then recall Skaggs to start Tuesday.
Skaggs was impressive last Monday when he started against the Rangers at Chase Field. Skaggs, ranked as the team's No. 1 prospect by MLB.com, tossed six shutout innings and allowed just three hits.
Delgado, who was acquired during the offseason trade that sent Justin Upton to Atlanta, got off to a rough start in Reno, but has pitched better of late.
