The San Francisco Giants open a three-game series with the Reds at Oracle Park on Friday, and ace Luis Castillo will take the mound for Cincinnati in the opener.
Back in 2015, he was a little-known Single-A reliever when the Giants packaged him along with another pitching prospect and traded him to the Miami Marlins for veteran Casey McGehee.
Whoops.
Overall, the Giants have a fairly clean history when it comes to cringe-worthy trades. Trading a young George Foster to the Cincinnati Reds and flipping Gaylord Perry for Sam McDowell stand out as the two major blemishes on the long, storied history of the franchise.
