I watched the first 4 games in San Juan (stupid Mets) and I'd have to say that it's pretty safe to start your pitcher there.
The dimensions are small, but the way the diamond is positioned in relation to the Trade Winds, the wind constantly blows in. Hard hit line drives will go out for home runs, but the pop flies that everyone figured would be hit out are getting caught up in the wind and falling in for outs.
Additionally, there is a LOT of foul ground, and a lot of balls can be caught that normally fall into the seats. This helps the pitcher just as much as the wind blowing in ...
