When will first Harper home run come?

With his Major League career under way one question about Bryce Harper is when will he hit his first home run? The player with the famous left handed power stroke that got him drafted has yet to put the first one in the books after eight games. It did take him 16 games to put his first and only home run at Triple A over the fence. With five of his eight hits being doubles Harper is hitting the ball with authority. That first home run is bound to come soon and then the flood gates will open. On the flip is how will the pitchers handle young Harper taking them yard? Will more attempts to rattle him following the blue print of Cole Hamels be coming? This could get interesting.
