Kenley Jansen Rejoins Dodgers, Expected to Have Heart Surgery in Offseason

After sitting out the Los Angeles Dodgers' road series against the Colorado Rockies, closer Kenley Jansen rejoined the team for Monday's series opener at the Cincinnati Reds, per Andy McCullough of the Los Angeles Times.

Jansen skipped the trip to Denver because of concerns about an irregular heartbeat.

A cardiologist visit Thursday and an exam Friday indicated he needs another ablation to correct his irregular heartbeat. It will likely be performed two weeks after the end of the season.

He first underwent the operation in 2012.

"My cardiologist said he was definitely going to find something in there," Jansen said. "That's why they did the MRI, too. They're going to study the heart more."

The 30-year-old was hospitalized Aug. 9 before a road game against the Rockies and immediately flown back to Los Angeles. The irregular heartbeat also caused him to miss time in 2011 and 2012.

While he returned to the mound Aug. 20, his health could remain a concern going forward.

On the field, Jansen has struggled this season compared to recent years, but he still has a 2.89 ERA across 62.1 innings and 34 saves in 38 chances.
