Bryce Harpertook several rounds of batting practice Thursday afternoon at Nationals Park and hit one home run into the upper deck in right field.

The left-handed Harper, who was sporting a mohawk, also hit at least a half-dozen other homers, including three in a row to left, center and right.

Harper was in Washington for his introductory news conference. He agreed to a $9.9 million, five-year deal with the Nationals last week.
