For many struggling teams, a large early deficit results in a lackluster effort the rest of the way.

The Chicago White Sox, though, keep battling. 

Omar Narvaez homered and drove in the go-ahead run with a single, Chicago relievers tossed seven scoreless innings and the White Sox rallied from a six-run deficit for a 7-6 victory over the Kansas City Royals on Sunday.

Avisail Garcia and Tim Anderson also homered for Chicago, which has won four of five.

Hector Santiago (5-3) allowed just two hits in four innings of relief to get the win. Jace Fry, the last of six relievers, got the final two outs for his second save.

Of Chicago's 46 wins, 26 have been come-from-behind affairs.

"It says a lot about them because they're fighting," manager Rick Renteria said. "Certainly a great team win."

Ryan O'Hearn, Whit Merrifield and Alex Gordon homered for Kansas City, which dropped to 2-13 in the rubber game of series this season.

White Sox starter Reynaldo Lopez needed just 11 pitches to retire the side in order in the first, but was rocked for six runs and three homers (on 46 pitches) in the second. O'Hearn started things with a two-run shot, Merrifield made it 5-0 with a three-run blast and Gordon added a solo shot.

"I wasn't commanding my pitches," Lopez said through a translator.

Kansas City starter Heath Fillmyer allowed just one hit in the first three innings, but then suddenly lost it. The right-hander faced six batters in the fourth and didn't record an out.

Jose Abreu and Daniel Palka had back-to-back singles to start things and Garcia hit a three-run homer to trim the deficit in half. After Nicky Delmonico singled, Anderson homered to make it 6-5. Narvaez followed with a solo blast to tie the score and chase Fillmyer.

"He just couldn't stop the bleeding," Royals manager Ned Yost said. "Second time around, they kind of got on him. Wasn't a bad pitch to Garcia, but from that point it snowballed on him and other pitches weren't that great of pitches.

"By the time I could get somebody up, the game was tied."

In the fifth, Narvaez gave the White Sox a 7-6 lead with a two-out RBI single off Brian Flynn (3-4), scoring Garcia from second base.
