The Diamondbacks traded Stephen Drew on Monday night and are expected to look for their shortstop of the future this offseason.

"We've been thinking about (next year's shortstop) all year already," Arizona general manager Kevin Towers said.

"There's not a lot on the free-agent market, so more than likely it's going to take a trade. We'll probably have to trade a good player -- or a couple of good players -- to find one."
