Casey Blake (back) day to day

SURPRISE, Ariz. -- Los Angeles Dodgers third baseman Casey Blake was removed from the team's split-squad game against the San Francisco Giants in Scottsdale on Saturday because of tightness in his lower back. He is listed as day to day.

Blake laid down a sacrifice bunt in the top of the first inning, then was replaced at third by Russell Mitchell in the bottom of the first.

The 37-year-old Blake, who also was sidelined for five days last June with lower-back spasms, was expected to see team physician Dr. Neal ElAttrache as soon as Blake returned to Camelback Ranch, but no further prognosis is expected until Sunday.

Blake is entering the final season of a three-year, $17.5 million contract with the Dodgers, although he does have a $6 million club option for 2012. Manager Don Mattingly has said he plans to rest Blake often this season to keep him fresh.
