• Right-hander Michael Wacha improved to 3-0 for Triple-A Memphis with a seven-inning win on Tuesday. Wacha allowed three hits and one run to Iowa (Cubs), while walking two and striking out six. Wacha retired 19 of the first 22 batters he faced before allowing the seventh-inning run.

• Cardinals outfielder Carlos Beltran informed Matheny that his lower back felt even better on Tuesday than it had on Monday, when he still felt good enough to play. It was on Sunday that Beltran alerted the Cardinals' training staff to some back tightness.

• Tuesday marked the end of a nine-game stretch in which the Cardinals played all night games. What would have been a day game last Sunday was moved to primetime after being chosen for an ESPN national broadcast.
