Rosales to start season on disabled list

GOODYEAR, Ariz. -- With news of an injury to infield candidate Adam Rosales coming out Tuesday, the A's roster is suddenly taking shape.

The versatile Rosales, out of options and in good position to grab a roster spot, will instead open the season on the 15-day disabled list with a left intercostal strain. He may soon be joined by Hiroyuki Nakajima, who suffered a left hamstring strain Tuesday.

That leaves Jed Lowrie in charge of shortstop, with Scott Sizemore and Eric Sogard teaming up as a nice platoon at second base to commandeer Oakland's middle infield come Opening Day. It also leaves roster room for first baseman Nate Freiman.

The 29-year-old Rosales, injured in Monday's game while making a throw to home plate, was batting .324 with three home runs and nine RBIs in 21 games this spring. This marks the second time in three years he will begin the season on the DL, having sat out the start of 2011 while recovering from a fractured right foot.

"It's too bad, too, for a guy that's finally healthy again and putting together good at-bats and playing every position," manager Bob Melvin said. "It's a tough one to lose at this point, so hopefully he's healthy as soon as he can be and back in the swing of things."

The recovery time for intercostal strains varies, but typically players require at least a month off before returning to game action.
