Chase Headley (thumb) went 1-for-3 with a double in his first rehab game with High-A Lake Elsinore on Friday. Headley served as the designated hitter in the game, as his thumb is still a little sore when he closes his glove, so isn't ready to play the field just yet. It's uncertain how many games he'll need on his rehab assignment, but all signs point to him returning to the Padres' lineup in a week or so.
