Blake played catch, took ground balls and hit off a tee, resuming activity after two light days to let an injection and anti-inflammatory medication kick in.
The Dodgers still don't expect Blake to be ready for Opening Day, because he will have missed so many innings and at-bats.
Blake, 37, is in the final guaranteed year of a three-year deal with an option for 2012.
Fellow infielder Jamey Carroll played catch for the first time in a week (with Blake) but still isn't playing in games because of the sprained right index finger that bothers him while throwing. He is able to hit and was scheduled to bat in a Minor League game, along with teammates Tony Gwynn and Marcus Thames.
