I guess I don't see a fit of team to park. Camden Yards is a homerun park. The easiest way to extract value from the game is to have a homerun park and have a bunch of 8 BP guys. Since Strat bases its salaries on an 8 8 homerun park all of your players will be worth more than their salaries. This is an optimization game and that is the easiest way to optimize your players. You have 9 guys with 8 bp homeruns you now have an advantage versus other teams. This is also not a good park for Robbie Ray--he gives up too many homeruns. You got bullpen guys with WHIP over 1 and costing less than 4. Your starting pitching is not dominant enoughto allow that I think. A 5 million R2 will provide value as they can give you 200-250 good innings.
Again, the question is always how do you extract value from your players so they are better than STRAT has them evaluated at? Ballpark fit, platoons, and expensive relief guys are the most obvious ones (I don't think that Strat is factoring Andrew Miller throwing 250 Innings.) Making sure you have a relief corp that fits the starting staff is important, too. Having an overall offense that fits the park is useful as well. There are a lot of other nuances of course but if your team does not fit your park I'm not sure you are going to overcome that no matter how well you manage your team otherwise.
Here is a power team I had this year that was ok.
