The first pitch of the penultimate round of the 2018 postseason will be thrown by a guy the White Sox traded. Twice.
A more noteworthy guy the White Sox traded (only once, though) could end up throwing the first pitch of the ALCS, too — his name is Chris Sale, you've probably heard of him — but let's instead focus on the guy who will take the mound in the top of the first inning of Game 1 of the NLCS. Gio Gonzalez is the Milwaukee Brewers' starting pitcher for Game 1 against the Los Angeles Dodgers, and he's a somewhat memorable figure in White Sox history in that they dealt him as part of the trade for Jim Thome in 2005, then reacquired him in the Freddy Garcia-for-Gavin Floyd swap a year later, then traded him away again the following offseason, that time to the Oakland Athletics in the Nick Swisher deal.
