Position battle: Diamondbacks shortstop

Back in February, ESPN.com's Buster Olney said that the Arizona Diamondbacks have "a good ol' fashioned showdown" on their hands this spring for their starting shortstop job, and whoever wins "bears a lot of responsibility, considering how the D-Backs have loaded up and taken their payroll over $100 million." It's now mid-March, and the winner of that competition may finally be in sight.
