Winn (thumb) is expected to resume swinging a bat Friday, Daniel Guerrero of the St. Louis Post-Dispatch reports.
Winn was placed on the 10-day injured list Tuesday with a small fracture in his left thumb, an injury he suffered Aug. 18 while sliding into second base. The Cardinals are optimistic that Winn will be able to return soon, perhaps as early as Sept. 1 when he's first eligible, but how things go when he swings a bat Friday will go a long way in determining his timeline.
