Who turns out to be the better major leaguer?

All sorts of things to analyze here.  Marrero has more pop in his bat than Lars, but his home park (assuming he sticks with Wash) is very much a pitcher's park.  I also wonder whether he will hit for a good average as he rises up the ranks.

Lars seems to have a bit of a cult following here.  He has definitely produced great results so far in Low A ball.  He's hitting for great average, and his contact rate supports the results.  The power isn't quite there yet, but I think it will come eventually.  I do not think he'll ever be a 40+ HR guy, but a slightly lesser version of Justin Morneau is not out of the realm of possibility.
