Manager Oliver Marmol said Saturday that Flaherty (shoulder) has begun plyometric drills to replicate his throwing motion, John Denton of MLB.com reports.
Flaherty is nearing the end of his two-week shutdown from throwing, and it's encouraging that he's been able to resume some activity with just under a week remaining until Opening Day. The right-hander will need some time to build back up after he received a PRP injection March 18, but he'll begin a throwing program soon and will travel with the team once it returns to St. Louis. It seems likely that Flaherty will require a stint on the injured list to begin the regular season, but his progress late in spring training has provided a reason for encouragement.
