Here is a look at some of the top comparables to the Twins top starting pitchers: Francisco Liriano, Scott Baker, Carl Pavano, Scott Blackburn and Jason Marquis. The rotation was taken from MLB Depth Charts. One thing that stands out to me (non Twins subject matter expert) is the number of ground ball pitchers the Twins have on their staff.

In this exercise I used 2010-2011 data, looking at the skilled stats of K/9, BB/9 and GB/FB, while coming up with a similarity score based on these three stats for each Twins starting pitcher. The cutoff was having pitched at least 150 IP as a starter over the last two years. Here is the top 25 list for each Twins starter. There is some bias when comparing NL pitchers with AL pitchers due to the slightly inflated strikeout rate for NL pitchers who don't have to pitch to a DH, so feel free to make a mental adjustment for those pitchers. If you wanted to take something like this to the next level, you could look at age, contract status, handedness etc... but I've chosen to look at these three stats which are highly controlled by a pitchers skill level.
