Blanks was scratched from Thursday's spring training game with a right Achilles injury, Andrew Baggarly of the San Jose Mercury News reports.
Blanks has had surgery on both heels and was dealing with pain in that same Achilles earlier in spring training. Blanks is in the running for a bench job in San Francisco if he can get healthy, but if not, it will open the door for a player like Grant Green or Gorkys Hernandez to grab that open outfield spot on the Giants roster.
