The Nats promoted Bryce Harper from A-level Hagerstown in the SALly League to Harrisburg in the Eastern League. Aside from the wisdom of skipping a level, the Nats are taking him from a league with an average OPS of .725 to a league with an average OPS of .720 and skipping a league with an average OPS of .689. It's the opposite of what the Royals have done with their hitters, forcing them to hit the Midwest League (.690) and the Carolina League (.689) before letting them hit in the friendlier environments of AA and AAA. I prefer the Royals' approach.
