"If his foot's fine, his arm's fine, we feel comfortable," Arizona manager Chip Hale said. "He hasn't missed that much time."
Delgado is 4-3 with a 2.79 ERA in 41 appearances. The right-hander has given up just one earned run in his past 13 2/3 innings.
Worth noting
• Infielder Phil Gosselin (broken thumb) was scheduled to begin his rehab stint Monday in the Arizona Rookie League. Hale said they are setting a rotation for Gosselin to make starts at second base, third base and shortstop. Gosselin has not played for the D-backs since getting traded from the Braves on June 20.
