Blanks was released by the Giants on Friday, Alec Pavlovic of NBC Sports Bay Area reports.
The oft-injured first baseman batted just .232 in 34 games with Triple-A Sacramento, so the Giants opted to part ways with him to make room for other higher-upside prospects. Blanks has a good amount of big-league experience to his name, but his injury history could deter any potential suitors in free agency.
