He's in pretty good company. Taking a look at the graph below, you can see his Isolated Power (ISO) increased steadily as the season went on.

Unfortunately, the increased power came at the price of his strikeout percentage which also increased steadily. He was one of the ten worst players in strikeout percentage.

There's no doubt that Ryan Howard has tremendous potential, especially looking at his power numbers. However, if he wants to hit for power and average, he must learn to pick his pitches better.
