The Arizona Diamondbacks expect to operate with a payroll in the $100 million range, which wouldn't give them much wiggle room to improve the roster this offseason.

They only have four players under contract currently -- Zack Greinke, Paul Goldschmidt, A.J. Pollock and Yasmany Tomas. The four will make around $60 million in total salary. However, a host of arbitration players are projected to make around $30 million.
