General manager Jed Hoyer didn’t plan to make this road trip.

But with the Cubs buried in last place, and Dale Sveum making cryptic comments about core players and answering questions about his own job security, Hoyer showed up at Great American Ball Park and gave his manager a vote of confidence.

“He’s got our full support,” Hoyer said Tuesday. “We’re all in this together.”

There’s enough anxiety to go around. The Cubs had to sit through 10 more innings before finally beating the Cincinnati Reds 4-2 and getting to blast loud rap music in the postgame clubhouse.

The Cubs are 6-13 and don’t give Sveum any easy days at the office. Carlos Villanueva (1.53 ERA) pitched into the ninth inning before Carlos Marmol gave up the game-tying single to Joey Votto. Darwin Barney put them ahead in the 10th with his first home run and Kevin Gregg closed it out for his first save.

“We needed it,” Villanueva said. “You can’t dwell too much on those close games. They’ll crush the spirits sometimes.”

Hoyer and president of baseball operations Theo Epstein rarely traveled with the major-league team during their first year in Chicago, spending time in the office, scouting for the draft and visiting minor-league affiliates while allowing Sveum to run the show.

There were almost no outside expectations for Year 2 of this rebuilding project, but there have been breakdowns across the board.

A closer controversy sparked in the ninth inning on Opening Day and the bullpen has now blown six saves. The defense has committed 18 errors through 19 games. The lineup entered Tuesday hitting .147 (19-for-129) with runners in scoring position, which ranked worst in the majors.

“It’s been painful to watch because we keep on squandering leads,” Hoyer said. “That’s on Theo and that’s on me. We look at it and we have to figure out ways to get better. We’re not the most talented team in the league right now. We’re trying to build to get there.

“But as we get there, we can’t continue to make the kind of mistakes we’ve been making. We have to clean it up. We have to get better. That’s on us. Dale has our complete support. (Job security is) not what he should be thinking about in the least.”

Sveum lost enough patience that during Sunday’s media briefing in Milwaukee he floated the idea Anthony Rizzo and Starlin Castro could get demoted to Triple-A Iowa. The manager answered multiple questions about those two potential franchise players and would not rule out the possibility. Message sent.
