After they won a National League West title in their first season together, the Diamondbacks have rewarded manager Kirk Gibson and general manager Kevin Towers with new contracts. The new deals are for three years. Arizona CEO Derrick Hall said the new deals for Gibson and Towers include club options for an additional two years. "I really enjoyed watching the two of them work together," Hall said. "Obviously I was pleased with the results from the first season. Kirk Gibson, in particular, proved that he is a major league manager, as prepared as any I've ever seen, and I felt they were both worthy of extension." Hall said he would decide shortly after the 2013 season whether to exercise the pair's options for 2015 and 2016.
