Roberts, 36, has spent his entire 13-year career with the Orioles, so he's obviously familiar with the AL East. He sports a career line of .278/.349/.412, though he hasn't had a full, healthy season since 2009.
In 77 games last season -- his most since 2009 -- he hit .249/.312/.392 (89 OPS+) with 12 doubles, a triple, eight homers, 39 RBI and 33 runs.
Roberts enters into a crowded, yet complicated, infield mix for the Yankees. They're getting back Mark Teixeira and Derek Jeter from serious injuries while Alex Rodriguez's standing at third base remains tied to whether or not he wins his appeal against what could amount to a season-long suspension. Kelly Johnson could play second or third, while Brendan Ryan provides insurance for Jeter at shortstop. Roberts represents another option at second while Eduardo Nunez could still fill second, short or third if need be.
As reported on CBSSports.com Monday night, the Yankees were looking at Roberts, Mark Reynolds and Michael Young for infield depth. It's still possible they sign Reynolds or Young, too.
