CHECK THIS OUT! Not only is Phil using Callaway prototype irons, but he is also carrying the Callaway Epic Pro iron! However, notice that it is not the longest iron; it is actually a 4-iron. The Callaway Epic Pro irons is an absolute distance gain, so Phil does not need to use the 3-iron. Having the Epic Pro 4-iron gains Phil distance, as well as control since it is not as long.
