The Pirates walked off after an error by the White Sox catcher to win 5-4 at PNC Park.
Kevin Newman tapped one back to the pitcher and Yasmani Grandal wasn't able to handle the shovel throw at the plate, which allowed the winning run to score.
Ke'Bryan Hayes tripled in a run in the fifth and Newman singled him in, and Jacob Stallings had a run-scoring double in the eighth followed by a run-scoring single by Erik Gonzalez.
Richard Rodriguez took the win in relief.
