Worth noting

• Matheny has no set number for callups once August comes to an end.

"I've never been a part of a club that had too many," Matheny said. "What's too many? Sometimes a younger player just needs to be exposed to the culture of a pennant race. If they are sponges, it's a great opportunity."

• Matt Carpenter entered Saturday riding a six-game hit streak. In that time, he's hit .375 (9-for-24).

• Matheny expects the Cardinals to call up an extra pitcher for next Saturday's day/night doubleheader against Chicago. The doubleheader includes a makeup game at 1:15 CT after the May 14 game between the two franchises was rained out.
