Castellanos, obtained last summer from St. Louis in the Rafael Furcal trade, was an outfielder in the Cardinals system. This year at Triple-A Albuquerque, he played 84 games in the infield and only four games in the outfield.
But with the Dodgers, manager Don Mattingly has used him in the outfield, most recently in Saturday's nail-biter, when Castellanos was inserted for Juan Rivera as a pinch-runner in the top of the eighth inning and remained in the game in left field.
Naturally, the game found him with two out in the bottom of the ninth. Gregor Blanco's high fly in the sun and the wind sent Castellanos lurching into the fence, with the ball bouncing out of his glove for a double. But reliever Brandon League got pinch-hitter Hector Sanchez on a line drive to third to preserve the 3-2 Dodgers win.
