No reason was given in the documents, but the petition for a dissolution of marriage was filed Monday, the records show.
Meanwhile, the Cubs star filed a complaint for legal separation in Tennessee accusing his wife of "inappropriate marital conduct."
Ben Zobrist was granted a “leave of absence due to personal reasons” last week and was placed on the Cubs’ restricted list. He also missed the start of the team’s spring training in February for an “excused absence,” though it remains unclear if either is connected to the divorce proceedings.
"I texted with him the other day, reminded him how much I care about him, and about how much we miss him," Cubs manager Joe Maddon told the Chicago Sun-Times before the team's Tuesday game in Cincinnati.
Julianna Zobrist, a professional singer who has previously sung the national anthem at Cubs games and also performed at a 2016 World Series game at Wrigley Field, hired Berger Schatz attorney Karen Krehbiel to represent her in the matter.
The Chicago Tribune reports Krehbiel also represented Chicago billionaire Kenneth Griffin in his divorce from Anne Dias Griffin in 2014. Krehbiel's office declined to comment on the matter.
The couple has been married for 14 years and has three children together.
The news comes just days after social media users noticed that Julianna Zobrist had deleted her Twitter account, and that she had deleted numerous photos from her Instagram profile that featured her husband.
