According to the depth chart on Yahoo! Sports, Willie Harris is supposed to be our starting center fielder where Nyjer Morgan is slated to be the back up left fielder. I think they're a little confused.
Splitting time between playing centerfield in Washington, and both left and centerfield in Pittsburgh, Morgan was the second most valuable fielder in baseball registering 27.8 runs above average. First was Seattle Mariners outfielder, and former Cleveland Indian prospect Franklin Gutierrez (29.1), and third was Rays shortstop Ben Zobrist. (26.4). Nationals third-baseman Ryan Zimmerman finished fifth with 18.1 runs above average.
