No makeup date was announced for Friday night's game. Saturday's game was pushed back from 1:10 p.m. ET to a 7:10 p.m. start.
Rain began shortly before the 8:10 ET start time and the forecast called for continuous showers throughout the night. It's the second rainout at Busch Stadium, which opened last year.
The Cardinals pushed back Anthony Reyes, who had completed his warmups, to Monday with Kip Wells starting on Saturday. Ben Sheets, the Brewers' scheduled starter, was pushed back to Sunday with Jeff Suppan starting on Saturday.
