Chase Headley (thumb) could be activated from the disabled list as soon as Tuesday. Headley went 1-for-3 with a double in his first rehab game Friday, and his thumb felt fine on a broken-bat jam shot and a ball that went off the end of his bat. The third baseman said the appearance "couldn't have gone better." Headley needs to test out the thumb on defense, which he will do on Sunday and likely Monday. If he passes that test, he could be in the lineup on Tuesday against the Dodgers.
