Mat Latos might begin the season not atop the mound in St. Louis, but on the disabled list.

Latos missed what was scheduled to be his final spring training start Saturday with a shoulder injury, and manager Bud Black said there's no timetable for when Latos will resume throwing.

Asked whether Latos is a candidate for the disabled list, Black said, "Sure, oh yeah. It's an option."

Black confirmed that Latos' injury is an inflamed bursa sac.

"This, from what I've been told," said Black, "can turn (in a positive direction) quickly. And it can also be a little bit of time."
