Anderson exited Saturday's contest with a blister on his left middle finger, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Anderson was visited by trainers in the seventh inning after surrendering a solo home run to Miguel Sano. He exited without throwing another pitch and was later diagnosed with a blister. It's unclear if he will be placed on the injured list or if he will have his next start pushed back or can continue on his normal schedule. Prior to exiting the contest, Anderson had allowed three earned runs on four hits and a walk while striking out two. He did not factor in the decision.
