KANSAS CITY, Mo. (AP) — Jacob Petricka had been joking with White Sox pitching coach Don Cooper that they were just waiting for the right moment for the reliever to make his big league debut.
How about runners on first and second and one out in a tied game in Kansas City?
In extra innings, no less.
Petricka induced a double-play grounder to end the Royals' threat, and then watched Conor Gillaspie hit a leadoff homer in the 12th inning that powered Chicago to a 4-3 victory and its first three-game sweep in Kansas City in more than four years.
"We were just waiting for the right time," Petricka said with a smile. "Guess tonight was it."
Addison Reed preserved Chicago's season-best sixth straight win, and the first of Petricka's career, when he left the tying run on second base for his 34th save.
Reed walked Billy Butler to start the 12th, and pinch runner Jarrod Dyson swiped second base with nobody out. Reed recovered to strike out pinch hitter David Lough, and Chris Getz lined out to shortstop. Reed then retired Emilio Bonifacio on a lazy fly ball to end the game.
"I felt like I had enough to get through another night," said Reed, who has closed out each of Chicago's last six wins. "If I'm in, it's a good thing. I'm going to do everything I can to prepare myself if I need to throw the ninth tomorrow."
Gillaspie's homer came off Luke Hochevar (3-2), and just cleared the outstretched glove of right fielder Justin Maxwell. It bounced off a sign behind the wall and back into play, and for a moment there was some question whether it should have been a ground-rule double.
"I was close," Maxwell said. "I had a pretty good bead on it."
