In a strategic adjustment to their pitching rotation, Sonny Gray will now start for the St. Louis Cardinals in the series opener against the Washington Nationals. This change pushes Andre Pallante to Wednesday's game, after Gray has had five days of rest since his last outing against the Pirates. This adjustment is primarily to ensure Gray can pitch against the Braves in the final game before the All-Star Break. Meanwhile, Pallante, fresh off a seven-inning scoreless performance, will be well-rested for his start.

As Miles Mikolas continues to hold on to his spot despite recent struggles, he is set to pitch the series finale on Thursday, potentially facing scrutiny due to his performance, which has seen him allow 14 runs, including six home runs in his last two starts. For the upcoming weekend series against the Braves, Matthew Liberatore is expected to pitch on Friday, and the Cardinals are still determining whether Erick Fedde or Michael McGreevy will take the mound on Saturday. Fedde's recent performance has raised concerns, as he has not lasted beyond the second inning in his last start.
