UPDATE: This story has been updated with new information since it was first posted.

Nationals infielder Anthony Rendon fractured his left ankle when he slipped and fell during a high Class A Potomac game on April 6. Washington general manager Mike Rizzo told CSN's Mark Zuckerman that Rendon will see a specialist tomorrow to further examine the injured ankle.

When contacted by Baseball America, Nationals farm director Doug Harris said, "We are assessing and treating him and his status is to be determined."

The left ankle injury is the latest in what has become a long-line of significant injuries for Rendon, the sixth pick in last year's draft and the 2010 College Player of the Year. Rendon was largely limited to DH as a Rice junior because of a strained throwing shoulder–an injury that eventually kept him from going to the Arizona Fall League. The year before he broke his right ankle while playing for Team USA and he also tore ligaments in his right ankle in 2009.

Before the latest injury, Rendon had dazzled Nationals officials with an excellent showing during spring training. He played some third base, second base and even shortstop.

"He was in a good place physically and mentally. He made some adjustments in the course of the spring. He played defense well and swung the bat extremely well," Harris said. "He's a very instinctive defender."

In other Nationals' injury news, Harris said outfielder Brian Goodwin is recovering well from the leg injury that recently led to him being placed on the seven-day disabled list. Goodwin, the Nationals' supplemental first-round pick in 2011, sustained the injury while legging out an infield hit.

"He's progressing well," Harris said. "Obviously we'll be conservative (in setting the timetable for his return)."
