Top draft pick Anthony Rendon injured himself running the bases last night.
X-rays taken on Rendon's ankle were negative, according to another club official, but the organization won't have a timetable for his return until swelling has diminished and he's able to be re-examined by doctors.
Rendon had doubled in the top of the fourth inning and was trying to score on Justin Bloxom's subsequent base hit to center field when he slipped coming around third base and fell to the ground, according to eyewitnesses.
The 21-year-old third baseman lay motionless for several minutes before he was helped off the field, his left leg kept off the ground the entire time with no weight being put on it.
Rendon, the sixth overall pick in the country, saw his amateur career sidetracked multiple times by injuries. He fractured his right ankle while playing in 2010 for Team USA in international competition, and he was unable to play in the field for most of last season due to a right shoulder strain.
In two games so far with Potomac, he's 2-for-4 with a double, a triple and two walks.
