According to Baseball-Reference.com, the batter most similar to Michael Young is Carlos Guillen. So to say that they’re “comparable” is a pretty fair description.

[…] Also, there’s been some good dialogue going about how this will affect the shortstop free agent market.  A lot of people have been comparing Young to Carlos Guillen, who the Tigers have to sign or becomes a free agent at the end of this season.  Tigerblog thinks Guillen is just as good as Young while Rangerfans thinks otherwise.  I’m with Joe on this one.  Guillen is good, but he’s not going to come anywhere close to what Young will do over the next five years.  My opinion anyway.   [link] […]

They’re very close in on-field ability. Young has a significant edge in durability, which may be a bigger issue as the two players enter their 30s. Guillen is more likely to miss games, and his long-term prospects are more questionable. There’s already been some talk about moving him away from SS because of declining range.

For 2007, they’re more or less even. For the longer term, Young is a safer bet.

I’m apt to agree with jvwalt. Over the next two or three years I’m happy with Guillen, but past 2010? I’m not so sure.
