Behind door #15 we find...Corey Hart!
Depending on who you ask, today's prize in the Advent Calendar is either completely worthless or could be traded for a frontline starting pitcher.
One thing is for sure, though: Hart's terrible September in 2008 was one for the ages, and not in a good way. In fact, Hart's September 2008 OPS was lower than any other 2008 Brewer with a minimum of 25 PAs had in any month:
| Player | Month | OPS |
| Corey Hart | September | .437 |
| Craig Counsell | July | .460 |
| Bill Hall | June | .476 |
| Craig Counsell | May | .479 |
| Jason Kendall | July | .492 |
| Bill Hall | September | .500 |
| Mike Cameron | September | .510 |
| Jason Kendall | September | .593 |
| Joe Dillon | June | .593 |
| Jason Kendall | May | .600. |
