Back in 2016 at the July trade deadline, the Milwaukee Brewers traded Will Smith to the San Francisco Giants for then-top Giants prospect Phil Bickford and backup catcher Andrew Susac. Susac never amounted to much in the big leagues and Bickford has gone through his own set of issues on and off the field. His prospect stock has dropped considerably.
Since being traded to the Giants, Smith required Tommy John surgery in 2017, but returned in 2018. Now that the Giants are looking to scale back a little bit, they appear to be open to trading the lefty reliever.
