The three teams with avian nicknames are all having their problems this season.
The defending World Series champion Cardinals entered the weekend six games under .500. Their top starter, Chris Carpenter, is on the shelf recovering from elbow surgery, they were last in the league in runs, and Albert Pujols' slugging percentage (career .629 entering the season) was .413.
The Blue Jays, 10 games out of first in the AL East entering Friday, have already used the disabled list 11 times - as many as all of last season. They have lost their closer, B.J Ryan, for the season with an elbow injury, and are without top starter Roy Halladay, who has appendicitis.
And then there are the Orioles, who had lost 16 of 23 entering Friday. Two Orioles, Melvin Mora and Jay Payton, nearly came to blows as tempers flared after a 5-3 loss in Toronto on Monday night. Mora and Payton were restrained by teammates and later made peace.
"There's nothing wrong with this clubhouse," Payton told the Baltimore Sun. "Guys are just tired of losing, that's all."
