LaRoche tried out at LF

Dodgers MLB website has a good article about Andy LaRoche being tried out in LF.

So far he's played there one game (IIRC) and handled his fielding chances adequately.

"When you put a player in a new position they seem to hit balls at them right away," said manager Grady Little. "I don't know if it's coincidence or the baseball gods. Sure enough, they hit a couple but he [La Roche] handled them well."
Do you think it makes sense for the Dodgers to experiment with LaRoche out of his natural position at 3B? Especially that he's not such a good fielder (by default) as Loney (great with the glove at 1B and more than capable in limited tries at RF). And especially that both Gonzalez and Ethier (if not playing RF) are clearly ahead of LaRoche on the OF depth chart. Plus there are both Bigbie and Anderson as spare corner outfielders.

Do you really think Andy can't be a "proper" backup 3B for Betemit on the active roster come April 1? There is still plenty of time for him to beat Betemit to the starter's job, mind you. Why mess up putting him at LF?
