It was previously reported that Melvin Mora had signed a two-year contract with the Diamondbacks. Updating that item, Nick Piecoro reports that the contract will be for one year and just over $2 million (Update: it'll be $2.4 million). It's possible that there's a 2011 option in place that's contributing to the confusion, but Piecoro's version sounds a lot more reasonable for the soon-to-be 39-year-old infielder.
Mora is expected to replace the departed Mark Reynolds, who was traded to the Orioles in exchange for two young righties earlier Monday morning. Mora doesn't offer Reynolds' power, but he also doesn't strike out nearly as often, and is versatile in the field. On top of that, Reynolds was dumped in part because of his price, and Mora comes cheap.
Expect Mora to generate some trade interest during the season as contenders look to fill out their benches in preparation for a playoff run.
