CHICAGO -- Just about a month after he'd hit the most controversial home run of his career, Adam Rosales hit one that carried further, both figuratively and literally.

Rosales' 383-foot blast down the left field line in U.S. Cellular Field snapped a tie Thursday and gave the A's a 5-4, 10-inning win over the Chicago White Sox. And for the Chicago native, it came with his mom, Deborah, and his wife, Callie, in the stands.

"I've hit a homer here before, but never like this," Rosales said after the A's locked down their 17th win in 20 games when Grant Balfour ran his 2013 saves mark to 14 for 14. "It's a great feeling to put the team up by a run in the 10th inning."

Contrast that to the happenings of May 8 in Cleveland, the umpiring crew led by acting chief Angel Hernandez disallowed a ninth-inning homer by Rosales that would have tied the game. Video afterward showed that the ball was indeed a homer, having hit a railing behind the home run line on the fence, but the damage was done.

This time Rosales took no chances and did the damage himself. Batting with two out, he drilled a Matt Thornton pitch not just over the fence, but beyond most of the fans who were sitting in the left field bleachers.

"I've put that one behind me," Rosales said. He was credited with a double that night. "But every time I think of the home runs I've hit, I'll still add one to the total."

The A's wound up hitting four home runs on the night, the first two being bases-empty blasts by Yoenis Cespedes, his second two-homer game in three days. And Josh Reddick, the team's home run leader a year ago with 32, ended a 30-game homerless streak with a monster blast that tied the game in the seventh.

But this game belonged to Rosales as much as to anyone. His double in the fifth inning scored Nate Freiman with the A's second run. It was quite a night at home for a player who came into the game with a .120 average in his last 50 at-bats.

It may be a sign that things are turning for the shortstop, who starts only against left-handers. And the A's couldn't pick a better time for him to get his bat back, because they will see left-handed pitching in the four games in Chicago.

"That first hit really helped get some of my confidence back," Rosales said. "It was a big hit for me and a big one for the team, getting us close and helping us come back after being down three runs early."

And then there is the hometown factor. Rosales is proud of his Midwest roots and loves getting the chance to play in Chicago.

"I grew up a Cubs fans, but I came to a lot of games here," Rosales said. He lives in Park Ridge, Ill., in the offseason and is staying there for this series. "To do this here, it's unbelievable.

"And to do it with my mom, my aunt, my wife, my uncles and some close friends in the stands, that makes it all the better."

Manager Bob Melvin has stuck with Rosales to play shortstop against left-handed pitching in part because the A's have been doing well enough that he could afford to wait for the right-handed hitting infielder to come around.

The A's have been hitting well, but if Rosales, Cespedes and Reddick can crank it up, the A's will be a tougher team to beat down the road. All three have spent time on the disabled list, and Thursday's game may serve as a turning point when all three seemed to get their game back.

"It takes a strong man to do what Cespedes did with that second homer and hit it out to the opposite field into the wind," Melvin said. "And Reddick pulled that ball a long way to right."

And the A's train keeps on rolling.

  • The A's used their first pick in the draft, the 24th pick overall, to take Billy McKinney, a left-handed hitter with above-average power from Plano (Texas) West High. A center fielder as a prep, he'll probably be asked to play left or right if he turns pro. He has signed a letter of intent with TCU.

    In the second round, the A's chose left-hander Dillon Overton from the University of Oklahoma. The A's finished the night by taking shortstop Chad Pinder from Virginia Tech in Round B of the Competitive Balance picks.

  • The four homers are a season-high for the A's, who are a season-best 12 games over .500 and just one-half game out of first.

  • Balfour, in addition to converting each of his 14 saves this year, has saved 32 in succession dating to 2012.
