The Marlins have only played a couple of exhibition games and batting practice sessions in their new home, but already a pattern seems to be emerging: when the retractable roof is open, there's a steady jetstream out to left field that can carry balls a long, long way. With the roof closed, however, the park dimensions rule the day, and homers are much tougher to come by.

Now, this is based on a teeny tiny sample of just a couple of days observation, so don't go adjusting any cheat sheets. And even if the pattern holds, the weather in south Florida will be the biggest determination on how often the roof is open. But if it's true, this could be crucial information for owners in daily transaction and salary cap leagues, where right-handed Marlin sluggers like John Buck and Gaby Sanchez could outperform their price tag handily when the roof is open, the sun is shining down on them, and their fly balls lofted to left just keep carrying and carrying and carrying...

Of course, none of this will matter for the legend that is Mik... err, Giancarlo Stanton, who we all know is a lock for at least 92 home runs no matter how the park plays.
