"I think it's probably wise that we get him out to make sure that the groin is fine," Black said. "That he can withstand playing a ballgame and all that's entailed about getting loose, taking batting practice, playing in a couple games before the big league level."
Gyorko strained his right groin running the bases during a game on June 10 against the Rockies. On Monday he hit, took ground balls and ran the bases, all without pain.
The Padres haven't decided whether Gyorko would begin his rehab assignment on Tuesday or Wednesday.
"We're working through the scenario of getting Jedd out to play in a Minor League game or two, and then from that point on we'll see how his leg is doing," Black said. "Then we'll make a determination whether he joins us when we're on the road."
Gyorko's return will give the Padres one of the best hitters in their lineup back. Gyorko is hitting .284 with eight home runs and 25 RBIs, and he had a .325 average in nine games in June before getting hurt.
