Yankees hitting coach Kevin Long worked with Cano this season to improve his ability to turn on the inside pitch. Here are his SLG% heat maps for the last 3 seasons.
You can see that Cano improved significantly on pitches inside in 2010.
Cano has also put more distance under his fly balls in each of the last 3 years.
The Yankees have a number of veteran hitters that are in their decline years. Jeter, who is sure to sign soon, had an awful 2010. Alex Rodriguez's power has been in the decline since 2007. While some of his problems in the last two seasons were probably due to his hip injury, he's not likely returning to his mid decade MVP form.
At 28, Robinson Cano still has some of his best hitting years ahead of him, something this aging Yankees lineup will need.
