The Arizona Diamondbacks will decide between Chris Owings and Didi Gregorius at shortstop, but the decision could be finalized sooner than expected if a trade is made.

"It's been pretty quiet of late," Kevin Towers said of the trade market. "With Stephen Drew still out there right now, I haven't had much trade discussions."

Towers didn't shoot down the idea of a trade, even spelling out what Arizona would want in return for one of their shortstops.

"For us, it would have to be the right deal," Towers said. "Our biggest needs in our system are catching. If it's the right, top-notch catching prospect. Someone we could have right behind Miggy. More of an upper-level guy. Maybe a top, upper-end starter. We have a lot of bullpen depth, infielders. Maybe an outfielder, but probably more catching and Double-A, Triple-A type starter."
