Randal Grichuk, who has taken a step back again in a one-for-17 dive, will be replaced as the center fielder Saturday night in the Cardinals’ lineup by normal right fielder Stephen Piscotty. Brandon Moss, who is two for eight against San Francisco righthander Jeff Samardzija, will be in right field behind starter Michael Wacha, who will seek to break his personal losing streak at six.
Piscotty’s start in center is his third this season after he had one last year.
“It’s definitely different,” said Piscotty. “It’s a lot more about depth perception. All you can do is get more reps and more experience doing that.
