What happened: The Pittsburgh Pirates are acquiring infielder Jacob Gonzalez and left-handed reliever Brandon Eisert from the Chicago White Sox, sending back the 34th pick in tomorrow's draft and a left-handed reliever in return, sources tell ESPN's Jeff Passan. The deal is done.

Why it matters: Gonzalez, the same Jacob Gonzalez who hit his first career home run in a White Sox win, gives Pittsburgh a young infield option, while Eisert adds left-handed bullpen depth. Chicago recoups an extra day-two draft pick and MLB-ready pitching in return.

What to watch: Gonzalez and Eisert are expected to join the Pirates organization as Chicago sets to use the newly acquired 34th pick in tomorrow's draft.
