off base

Missing the mark

Off base means mistaken or wrong, especially about an assumption or judgment: Your estimate is way off base.

The phrase comes from baseball, where a runner caught off base can be tagged out—vulnerable because they're not where they should be.

It implies being not just wrong but noticeably so.
