Mark Buehrle is going to the Miami Marlins, C.J. Wilson is heading to the Los Angeles Angels, and closer Heath Bell is also going to the Marlins.
So, the free-agent market for pitchers this offseason has certainly dwindled significantly, but there's still some talent available.
Guys like Roy Oswalt and Hiroki Kuroda can be top-of-the-rotation guys.
Then, there's guys like Scott Kazmir and Edwin Jackson who can be a solid No. 3 or 4 on playoff contenders.
So, with that being said, let's take a look at the top five remaining free-agent pitchers.
If Rich Harden can stay healthy, he's a good starting pitcher.
However, he's too much of a wild card when it comes to finishing a full season.
When healthy, he's a strong power pitcher, with a 2:1 career strikeout-to-walk ratio and a 3.76 ERA.
If he can get back to his 2008 self, he'll be a steal for whichever team signs him.
Edwin Jackson changes teams more than a woman changes clothes.
But, despite the incredible amount of jerseys in his closet, Jackson's actually a pretty good starting pitcher.
He played a key part in the St. Louis Cardinals' 2011 World Series championship and, at 28, is entering the prime of his career.
He'll probably be adding another jersey to his collection this offseason, but that team will be getting a lot of value.
Prior to 2011, Scott Kazmir was a very reliable middle-of-the-rotation starter.
He's normally very durable and gets plenty of strikeouts.
There are plenty of teams that could use the lefty, so it'll be interesting to see where he ends up.
Hiroki Kuroda has incredible control on his pitches.
For his career, he has 523 strikeouts and only 163 walks.
Add in a career 3.45 ERA and it really makes you wonder how he only has a 41-46 record.
The New York Yankees are interested in Kuroda, and if he gets paired up with that offense, the sky is the limit.
RoyOswalt was the forgotten member of the Philadelphia Phillies' starting rotation last year.
Now, it appears he will be leaving the shadows of Roy Halladay, Cliff Lee and Cole Hamels.
He's still got the stuff to be a top-of-the-rotation guy for a few more years, with the Nationals and Rockies the most eager suitors at the moment.
If he gets the three or four-year contract he's searching for with a contender, however, he could regain the stardom he had in Houston.
