"We've had different guys out there," Matheny said. "That's not necessarily our goal. That's not how we want to do it. We'd love to have a lineup that we write in, and 162 games later, we're right where we want to be. But we've been struggling to figure it out.
"Our team is better when everybody is clicking. We have to get them going. We have to give them a chance."
Matheny also made a change at second base on Tuesday, this one based singularly on matchup. Mark Ellis, 1-for-14 in his career against Braves starter Gavin Floyd, sat in favor of Daniel Descalso, who had two hits in three career at-bats against the Atlanta righty.
The start was Descalso's sixth this season, and first since April 27. The lineup was the 29th different one used by the Cardinals in 34 games.
"We're going to need all these guys," Matheny said. "I hate saying it over and over again, but you hate going too long without giving them an opportunity to get in there more consistently than just one at-bat."
