ST. LOUIS (AP) Cardinals outfielder Jason Heyward is out of the starting lineup a day after being taken out of the game with left hamstring tightness, an injury manager Mike Matheny believes may have been cramping.
Rookie Tommy Pham started in center against the San Francisco Giants on Tuesday night.
Matheny is hopeful Heyward will be available soon for a team already minus three outfielders. Randal Grichuk, Matt Holliday and Jon Jay are all out with injuries.

Heyward is batting .287 with 11 home runs and 43 RBIs.
Matheny says Pham got the nod over veteran Peter Bourjos because he had been playing so well at Triple-A Memphis before being recalled when Grichuk went on the 15-day disabled list Monday with an elbow strain.
