| WEEK | RECORD | RANK | COMMENT | |
| Week 8 | 28-15 | 2 | Rookie John Gast filled in admirably for the injured Jake Westbrook as the Cardinals continue to roll, but Jaime Garcia landing on DL poses another hurdle. -- Matt Philip, Fungoes | |
| Week 7 | 23-13 | 1 | Matt Adams returned from the disabled list, Shelby Miller pitched one of the best games in team history and the pitching staff continues to be tops in the National League with a 3.11 FIP and a 3.39 xFIP. -- Matt Philip, Fungoes | |
| Week 6 | 20-11 | 3 | The Cardinals began the week a half-game out of first place in the National League Central, but after the bullpen got refreshed they've won six straight and are now 2 1/2 games ahead in the division. -- Matt Philip, Fungoes | |
| Week 5 | 14-10 | 4 | The Cardinals' rotation continues to be their strength, as they lead the National League in fielding independent pitching at 2.78, but their bullpen has been leaky (worst in league with a 4.46 FIP). -- Matt Philip, Fungoes | |
| Week 4 | 10-8 | 9 | Carlos Beltran heated up (three home runs/.400 OBP/.792 SLG for the week), but the Cardinals slipped out of first place as they split a four-game series with the Phillies. -- Matt Philip, Fungoes | |
| Week 3 | 7-5 | 5 | Fronted by Adam Wainwright (2.05 ERA, 0.85 fielding-independent pitching), Cardinals starting pitchers have the best ERA in baseball. -- Matt Philip, Fungoes | |
| Week 2 | 3-3 | 14 | After a stuttering first four games of the season, the Cardinals finished Week 1 outscoring their opponents 37-24. -- Matt Philip, Fungoes | |
| Week 1 | 0-0 | 12 | The Cardinals finished spring training a bit bruised, with Jason Motte and David Freese on the disabled list, but they're ready to begin the season with a deep lineup and pitching staff set to improve on last year's team strikeout record. -- Matt Philip, Fungoes | |
