Cubs place Jose Quintana on IL with injured pitching thumb

CHICAGO -- The Chicago Cubs placed left-hander Jose Quintana on the 10-day injured list on Thursday because of nerve damage to his pitching thumb he suffered before the start of summer camp.

The 31-year-old Quintana wasn't expected to be ready for opening day after cutting himself washing dishes at his home in Miami last month. He underwent surgery July 2 and resumed throwing on flat ground after his stitches were removed last week.

Quintana went 13-9 with a 4.68 ERA last year in his second full season with the Cubs. He was an All-Star for the crosstown White Sox in 2016.

The Cubs also placed infielder Daniel Descalso on the 45-day injured list with a sprained left ankle and announced that outfielder Mark Zagunis opted out for the season.

Chicago hosts the Milwaukee Brewers in the opener on Friday.
