The Minnesota Twins had their first setback of the year on Monday, just hours before the start of their 2017 season.

Minnesota rap performer Dessa said she was too ill to sing the national anthem at the home opener at Target Field.

“Seriously disappointed to announce that I won’t be able to sing the anthem at the @Twins game today,” she said in a tweet posted about 8:30 a.m. “Spirit is willing, stupid body is sick.”

The Minnesota Orchestra’s brass quintet performed “The Star-Spangled Banner,” but there was no singing replacement. (Fans were asked to fill in the gap.)

“I knew today that she was fighting it,” team spokesman Dustin Morse said of Dessa being under the weather.

Also scrapped from the Opening Day ceremonies was a military flyover by fighter jets. The Minnesota National Guard pinned the cancellation on low cloud cover.
