VIERA — The Nationals optioned top prospect Bryce Harper to Class A Hagerstown on Saturday, saying the top overall pick in last year's draft needs to get more playing time to prepare for the season.
"He needs to go down to the minor leagues and get four or five at-bats per game to prepare himself for the season," general manager Mike Rizzo said. "And that was the reason we got him out."
Harper, 18, who hit .389 in 13 spring games, was disappointed but determined to make it back to the big leagues as soon as possible.
"Nobody likes to leave the big-league club," he said. "This is the life that you want to live every day, and it's just the process.
"I'm going to go down there and play hard like I always do and, you know, hopefully get back up here real soon."
