The Nationals reacted to Atlanta's acquisition of Justin Upton on Tuesday, largely believing that their National League East rival has improved considerably.

Washington will be looking to win their second-straight division title in 2013.

However, one member of the Nationals questioned why the Braves would trade Martin Prado as part of the deal with the Diamondbacks.

"I don't know why they got rid of Martin Prado, because he rakes," Bryce Harper said. "He was a killer horse against us last year and he is pretty unbelievable."

Last season, Prado was 23-for-69 (.333) with 12 runs scored and seven RBIs against Washington.
