The Nationals have promoted Anthony Rendon to Class AA Harrisburg, moving their top prospect up a level only one week after he returned from a major ankle injury.
Rendon, the sixth overall pick in last summer's draft, began his professional career at Class A Potomac but fractured his right ankle in his second game and missed the next 3 12 months.
The 22-year-old third baseman played in 13 rehab games in the rookie Gulf Coast League and at short-season Class A Auburn, then was activated off the disabled list and rejoin the roster at Potomac last week.
In only seven games with the P-Nats, he went 7-for-23 with a double, two triples and three walks, prompting the Nationals to bump him up a level to Class AA.
Rendon was widely considered the top amateur talent in the country prior to the 2011 draft, but his stock fell after an injury-plagued season at Rice University and he dropped to the Nationals' draft position at No. 6.
To fill the roster spot Rendon held at Potomac, the Nationals promoted fellow third baseman Matt Skole from low-Class A Hagerstown. The 23-year-old tore up the South Atlantic League this season, hitting .286 with 27 homers and 92 RBI in 101 games.
