Eager to continue the fine pharmaceutical heritage that began with Ewing Kauffman, the Kansas City Royals signed outfielder Jose Guillen to a 3-year, $36 million deal on Tuesday.
The potential steroid suspension aside, are the Royals spending David Glass's new found money wisely? How about some charts!
Below are two charts showing Guillen's On-Base Percentage (OBP) and Slugging Average (SLG) by age. The difference between the top chart and the bottom chart is that Guillen's partial years have been removed (in '99, '01, '02 and '06, Jose appeared in fewer than 100 games for the season).
By removing the partial seasons, we can see that the Dominican fellow has followed a pretty standard career path, peaking at age 27-28 in the power department while maintaining some positive growth in the ability to get on base.
Walks as a percentage of plate appearances:
Again, Guillen has shown an improved eye at the plate over the course of his career.
Extra base hits as a percentage of hits and plate appearances:
Here is where it gets sketchy for the Royals. At first glance, Guillen appears to have a somewhat erratic ability to hit the ball hard when he makes contact, but overall looks like he is trending upward.
However, when you remove the years most likely to be affected by small sample size blips, he begins to look like any typical player. In terms of full-season ability, Guillen's power potential seems to have peaked when he was 27.
The Royals have just "fixed" their middle order power problem with a guy who looks to be on the decline in terms of hurting the baseball over the next three years.
The good news is that while Guillen now becomes the highest-paid player in team history, his contract is not exorbitant in the current market. Three years is a short enough time frame that Kansas City can cut their losses if Guillen fails to find rejuvenation in the fountains at Kauffman stadium.
That said, I'd still rather see them go after Miguel Cabrera.
