Jacobs' teammates responded by giving him the silent treatment in the dugout after he cleared the fences for the first time in a month.
"At first, I couldn't figure out where everyone had gone, but then I realized what they were doing," Jacobs said Monday night after Kansas City beat Detroit 4-3. "I started high-fiving the air because you have to play along.
"It was great -- I'll take that any day," he said.
The Tigers, meanwhile, were left to ponder why they're not getting a lot of those kind of clutch hits.
Detroit stranded four runners in the second and third innings and finished the game with seven left on base. Only Ryan Raburn had more than a hit for the Tigers, whose .258 batting average ranks among the AL's worst.
"Our offense overall is not doing the job," Detroit manager Jim Leyland said. "From top to bottom, it just isn't clicking.
"You certainly hope you snap out of it at some point," he said.
Detroit leads Minnesota by 1½ games and the Chicago White Sox by 2 games in the AL Central, but the offensively struggling team is clearly frustrated.
"We've got too many good hitters to be stranding runners all over the place like we are," catcher Gerald Laird said. "We've got to get it figured out over the next couple of months if we're going to win anything."
Kansas City has three straight victories for the first time since winning four in a row in mid-June.
Willie Bloomquist drove in three runs for the Royals on a home run in the sixth and a two-run triple in the eighth.
Raburn homered in the sixth and had an RBI double in the eighth, making it 3-all.
"Their bullpen guys left a couple pitches up, and we were able to take advantage," Royals manager Trey Hillman said. "That's something we needed to see."
"We couldn't come up with the killer hit," Leyland lamented. "It's not falling into place right now. We're not just hitting much."
The Tigers, who opened a homestand after losing two straight at Minnesota, had won eight straight at Comerica Park. They began the night 23-11 in Detroit for the team's best 34-game start at home since 1984.
Both teams got solid results from their starting pitchers.
Detroit's Armando Galarraga allowed a run on five hits and struck out seven over seven innings. The slumping Zumaya, though, followed and gave up two runs on two hits in only one inning.
