A new batting practice cap was unveiled, and another new American Flag cap was used, but no other changes took place.
The 2010 design for special holiday caps featured a white crown with a choice between either a red or navy blue bill. The Diamondbacks naturally went with red, although, similar to previous years, the red was a much brighter scarlet red, as opposed to the Sedona Red of the rest of the uniform.
A new BP cap was unveiled for the 2010 season. The piping that used to be on the sides and the front of the bill now went down the front of the crown and bill. This also marked the first red BP cap ever to be worn by the Diamondbacks. The BP jerseys were not changed from the previous season.
