they have already talked about him playing other positions, including 2 games this season in the minors at 2B.
this is what Davey Johnson had to say about Rendon in spring training.http://www.federalbaseball.com/2013/3/5 ... ootwork-at
"He's got an idea on how to get that bat on the ball," Johnson, the former major league second baseman said, "Got good hands. Good stroke. And he can play a lot of positions. I like him at third, and I also didn't mind him at short. And he's got some [aptitude] at second."
so you can add SS into those list of positions too.
the article says they want him to play a full season in the minors, but with Zimmerman injured, he's in Washington now.
they finish the article by saying this.
If he keeps hitting like he has throughout college and early in his pro career, they'll find somewhere for him to play.
would the Nationals have called up Rendon if they really felt like there was no chance he remains with the team once Zimmerman returns? if they only needed someone to fill in, they could have just used Steve Lombardozzi.
as long as Rendon is hitting, I don't see him going back down. but that's a big if since this is the first time he has been playing above AA. he might not be hitting well, but if he is, he's going to play.
I'm not suggesting Zimmerman and LaRoche sit every few days. there could be multiple players sitting once a week. sitting Zimmerman once a week could help keep him healthy, or having LaRoche sit once a week and use Zimmerman at 1B.
