The Diamondbacks are looking to trade Aaron Hill but are barely listening on Martin Prado, according to league sources.

Hill has slipped from two years ago, when he had a career year, and is batting .251 with eight homers and 49 RBI. Prado's numbers are comparable (four homers, 37 RBI, .274), but Arizona views him as a key asset because of his leadership abilities and versatility.

The two players have similar contracts, with Hill due about $28 million through 2016, and Prado $26 million.
