On a night when he hit another bomb, Billy Butler’s dribbler proved just as valuable.

Butler’s seeing-eye single in the sixth inning provided the go-ahead run and allowed the Royals to access their greatest strength, the bullpen.

It added up to a 4-2 victory over the Giants that kept the Royals sizzling. They’ve won five straight, 13 of 16 and moved to a season-best eight games over .500.

In playoff chases on parallel tracks, the Royals remained 2 1/2 games behind the Tigers in the American League Central chase and a half-game ahead of the Yankees for the second wild-card position.

At this point year ago, the Royals held a similar record but were further back in the standings, seemingly always in a chase mode with the leaders off in the distance. This year feels different.

“I think this team is better,” Butler said. “We have the experience from last year of competing and having an opportunity to get there. But this team, we’re figuring out a way to win every night.”

Friday, the sixth was the decisive inning. Omar Infante got it started with a one-out single. He moved to third when first baseman Michael Morse dove to stop Salvador Perez’s soft one-hopper but threw wide of second.
