Matt Carpenter's third-inning homer got St. Louis on the board, and back-to-back sacrifice flies by Shane Robinson and Kelly in the sixth made it a one-run game.Aoki drew a one-out walk in the seventh and scored on Gennett's double over the head of center fielder Jon Jay. Gennett came home later in the frame on a sacrifice fly by Jonathan Lucroy.GAME NOTEBOOK: Cardinals OF Matt Holliday (back) was scratched from the lineup. … Brewers SS Jean Segura (hamstring) missed his fourth straight game. … St. Louis committed a season-worst three errors, leading to three unearned runs.
