Put A Fork In Them

We are nearly a third of the way through the 2010 baseball season. With more than 100 games remaining for each team, it is hard to dismiss a team for postseason contention. For example, last year at this time did anybody think the floundering Rockies would reach the post-season? A managerial change to Jim Tracy got the Rocks started on a massive hot streak that carried them to October.
So while anything is possible in baseball, I'm going to list some teams that I have mentally eliminated from contention on the 31st of May, even if they are not mathematically eliminated...yet.
In the American League, the disaster known as the Baltimore Orioles are toast. At 15-36, the O's are an embarrassment. I hope the Orioles fire manager Dave Trembley so he can enjoy the rest of his summer. It would be a mercy firing. I think he's a sharp manager but he has nothing to work with.
I would also throw the Indians and Royals into the "no chance this year" scrap heap.
I still think the White Sox can make a run and that they are a better team than they've shown so far. So while Chicago is 8-games out and just a game and a half ahead of Kansas City, I won't dismiss them yet. But the Pale Hose are on life support.
In the National League, the Diamondbacks are a mess and aren't going anywhere except to fill out their NL schedule obligations. In the Central, I have three teams that are hopeless and helpless. The Astros, Pirates and Brewers will not taste the playoffs this year. I just heard Jim Mora utter "Playoffs? I just hope we can win a game" in my head.
In the East, I have not yet buried any team, especially Washington. The surprisingly tough Nationals are just 4 games out even though they are a game under .500. Plus, it looks like Stephen Strasburg will be called up in a week or so to bolster the pitching staff. That will be a major shot in the arm for Washington. Plus, they have the first pick in the June Draft next week and will likely select Bryce Harper, the so-called "LeBron James" of baseball. Harper skipped his senior season of high school ball and dominated at the junior college level. So while Harper wouldn't help the Nats this year, the future is looking bright in Washington.
So class, in summation, you can write these teams off like you would dismiss a smelly co-worker: The Orioles, Royals and Indians in the AL and the Diamondbacks, Astros, Pirates and Brewers in the NL.
