CHICAGO – Jose Quintana pitched effectively into the eighth inning, Alex Rios and A.J. Pierzynski hit back-to-back homers in the sixth and the White Sox beat the Detroit Tigers 6-1 Monday night to increase their AL Central lead to three games.

The Sox had lost seven straight to Detroit, managed just two hits against Rick Porcello (9-12) and were 0 for 10 with runners in scoring position when an error on Detroit second baseman Omar Infante gave them an opening.

Infante muffed Dewayne Wise’s easy, one-out grounder in the sixth. Paul Konerko singled to left to put runners at the corners and Rios lined a pitch over the wall in left center, his 23rd homer of the season. Pierzynski followed with his 26th to center field for a 4-1 lead, ending Porcello’s night and sending him to his sixth straight loss. Gordon Beckham added a two-run shot in the eighth off Octavio Dotel.
