The ominous tomahawk-chopping noise surrounded Carlos Marmol, the perfect soundtrack for a closer on edge. Cubs fans light up Twitter with their votes of zero confidence while the coaching staff doesn’t know – or won’t say – what’s wrong.

Marmol walked back to the dugout alone on Saturday night as the Atlanta Braves hopped in a circle at home plate. Fireworks went off at Turner Field, celebrating The Upton Brothers and a 6-5 walk-off win. The crowd of 38,498 jumped up and down to the techno music.

Silence hung over the visiting clubhouse. The only thing you really heard was the water running in the showers. After B.J. and Justin Upton hammered 93 and 94 mph fastballs into the center-field seats for the game-tying and game-winning home runs, Marmol was on the verge of losing his job.

“We’re definitely going to talk about it now,” manager Dale Sveum said.

Sveum identified Shawn Camp and James Russell as possible replacements. He wasn’t thrilled with Kyuji Fujikawa, who gave up three runs in the eighth inning, leaving no breathing room for Marmol.

General manager Jed Hoyer walked into Sveum’s office after Game 5. If it seems too early to make a change, well, Sveum pulled Marmol in the ninth inning on Opening Day.

By the time Marmol met with reporters at his locker – a pack swelling because of the Japanese media chronicling Fujikawa – he hadn’t spoken with Sveum yet and couldn’t say whether or not he’d be surprised by a change.

“I’m trying to go out there and do my best,” Marmol said. “I don’t say that it’s confidence. I got my confidence. They hit my pitch.”

The Cubs will discuss the potential benefits of moving Marmol to a lower-stress inning, because things clearly aren’t working in the ninth. The $9.8 million closer has faced 13 hitters and given up five runs on six hits, two walks and one hit batter, which translates to a 27.00 ERA.

Sveum was asked to identify Marmol’s biggest problem: Mental? Physical?

“I don’t know,” Sveum said. “If I knew that problem, I’d be a genius.”
