Most Orioles fans don't need a study to know that things have gotten pretty depressing in Birdland after 13 straight seasons of losing baseball. But in case you've had your head in a paper bag all these years, I'll pass along the findings of a recent study.

Avvo.com, a website that gives out medical and legal advice, claims that Baltimore is the third most depressed baseball city in America behind Washington and Oakland.

According to a press release, Avvo "evaluated the cities that are home to the 18 MLB teams that haven't won a World Series in the past 20 years, and also looked at the teams' on-field performance." Stats such as psychiatrists and divorce lawyers per capita, unemployment rate, heavy drinking rate, suicide rate, when a team fell out of contention, and other criteria were also considered.

"Baseball fans are incredibly passionate about their teams so it’s no surprise that they often suffer from bouts of depression and disappointment after a big loss or as a result of the seemingly endless succession of losing seasons," Avvo founder and CEO Mark Britton stated in the press release.

Clearly, it's not based on performance alone because Pittsburgh was 10th on the list even though the historically-inept Pirates haven't had a winning season since the first George Bush was in the White House.

Here's the top 10 on the list:

1. Washington

2. Oakland

3. Baltimore

4. Seattle

5. Houston

6. San Diego

7. Cleveland

8. Cincinnati

9. Chicago (Cubs)

10. Pittsburgh
