The Washington Times' Amanda Comak tweeted the information on Thursday afternoon:
Harper, who has hit in the seventh spot through his first four games, will make the jump in the lineup to hit in front of Adam LaRoche and Jayson Werth.
Nats manager Davey Johnson is not wasting time with his 19-year-old gem, as he rewards him for a hot start in which Harper has gone 5-for-13 with three doubles, two runs and two RBI.
Harper's speed and hustle make him a valuable piece of the order no matter where he is placed.
It will be interesting to see how pitchers pitch to Harper now. The game plan should be to tempt him with less-familiar off-speed pitches, but with LaRoche and Werth providing protection, pitchers might be forced to give him more fastballs to put in play.
It is a bold move by Johnson, but one that might pay off with huge dividends. Harper has handled the copious amounts of pressure with ease thus far, and the lineup change will be handled with no less poise and confidence.
