Haase was placed on unconditional release waivers by the Giants on Thursday, Justice delos Santos of The San Jose Mercury News reports.
Haase was designated for assignment by San Francisco on Friday, and he will now either be claimed by a new team or become a free agent. The 33-year-old has produced a .162 average with four home runs, nine RBI and eight runs scored over 74 at-bats in 29 contests with the Giants this season.
