Center fielder Jon Jay (left wrist stress reaction) has begun a Minor League rehab assignment and is expected back later this week. The Cardinals hope that left fielder Matt Holliday (right quad strain), first baseman Matt Adams (right quad strain) and outfielder Randal Grichuk (right elbow strain) are only a week or two behind him.
On the pitching side, Matt Belisle (right elbow inflammation) is also expected back by mid-September.
"That's a pretty good boost when you start talking about the guys who we could potentially be bringing back here," Matheny said.
