"Rua is a left fielder who can play multiple positions," Banister said. "A utility player is a guy who you have on your bench who can play multiple roles. Guys who can play multiple positions and the quality of their at-bats doesn't diminish, they are invaluable."
Rua has played all four infield positions in the Minor Leagues as well as left field. The Rangers, after activating him off the disabled list on Friday, want him to concentrate on left field and third base. He could play first if the Rangers need him.
Right now there is a greater need in left field, but that may be only temporary until Josh Hamilton comes back off the disabled list.
