Lucas Giolito simply dazzled in his postseason debut, stymieing the Oakland Athletics through six perfect innings and sending the White Sox to a 4-1 victory in the opener of their best-of-three wild-card series Tuesday.
On Tuesday, he didn't allow a baserunner to the AL West champions until Tommy La Stella's single up the middle to start the seventh. Giolito gave up one run on two hits over seven innings, struck out eight and walked one before giving way to Evan Marshall after a stellar 100-pitch outing.
Giolito got plenty of support: Jose Abreu hit a two-run homer and Adam Engel also connected for Chicago. Yasmani Grandal homered in the eighth.
Alex Colome, Chicago's third reliever, worked the ninth for a save to close out the 2-hour, 53-minute game.
Ramon Laureano's groundout in the eighth scored Oakland's lone run.
Dallas Keuchel (6-2, 1.99 ERA) pitches Wednesday following a successful first season with Chicago.
Chris Bassitt, drafted by the White Sox before being traded to Oakland in December 2014, takes the ball for the A's with victories in his last three decisions. Oakland kept six starting pitchers on the roster.
