Yesterday, Harper had to be removed from the field at a Nationals minor league intrasquad game after spraining his ankle stepping on first base to try to beat out a single. Harper, the first overall pick last season, underwent X-rays last night, and the results were negative. The Nationals consider Harper day-to-day and will find out more information after examining him today.

Still, Harper could miss significant time, including Hagerstown’s opener April 7 in Rome, Ga. General Manager Mike Rizzo said Harper’s injury is something called a “good” sprain, which means it is more severe than a mild sprain but does not present long-term issues.

Harper’s is similar to the sprain outfielder Corey Brown suffered during the second game of spring training March 1, and Brown has missed three weeks withouyt playing in a game. If Harper’s recovery takes as long, he would not return until after Hagerstown’s first game.

Today, Harper was seen using crutches to walk, with no weight on his left leg.
