• Due to rain showers soaking the fields at the Peoria Sports Complex, the Padres carried out all of their morning work Saturday indoors in the cages and bullpen.
"The conditions aren't right to go out there," manager Bud Black said. "It's a little slippery, a little muddy so it's a good day to get the guys off their feet."
• Chase Headley (strained right calf) continued his rehab in the weight and training rooms Saturday, but improvement with the nagging injury appears to be slow moving.
"He's progressing every day," Black said. "But I still think he's a ways away from really any productive swinging in the cage."
• Josh Johnson will make his Padres debut Monday in Scottsdale, Ariz., against the Giants. He is expected to work two innings.
