Yes!! His name is Bryce Harper and he is a power hitter. That blast reminded me of Harmon Killebrew and Frank Howard. The only guys -- probably in either league -- who could hit one that high, far, and deep into the seats.
Lerners (or DC taxpayers) will need to raise the foul poles with Harper hitting.
(Hondo once hit a line-drive down the LF line and out of DC/RFK. (Yes, I've mentioned it before). Umpire missed the call because it sailed so high above the foul pole. Opposing left-fielder was happy the drive was called foul, but told Howard and the New Nats later that he saw the ball all the way. Fair ball, and the only home run hit out of DC/RFK. Probably nobody is as strong as Frank Howard, but Harper looks like he hits them as hard as Killebrew.)
