Ball parks

What is the strategy for picking ball parks?
Consider for example a $33 million pitching staff; a $30 million staff?; a $26 million staff

There are lots of things that go into picking a ballpark. I always pick the park first then build team around it. It’s not so much how much you spend on your staff, it’s the make up of the staff. Do they have BP hr rolls or not? Are they good vs lefties or righties? Sorry don’t have specific answer since much to consider when choosing a BP.

If there are many factors, what others are considered? If you pick the park at the outset, is the point that the number of hr rolls on a pitcher's card (and the others on the staff) is one of the relevant factors (I assume if the selected park is easy to hit hr's in. What others?

Choosing Your Ballpark

- In an Auto List Draft league, choosing your ballpark is Step 3, after you've filled out your 25-player Draft Card and ranked your players, and before Step 4: Joining a League.
- In a Live Draft league, you choose your ballpark any time immediately following your draft and up until 11:59pm ET on Sunday, the night before the season starts.

On the Choose Your Ballpark page, a list of ballparks is shown, along with each one's ballpark effect numbers. Each of the available ballparks has an effect on certain line drives that could fall in for singles, and certain deep flies that could go over the fence for a homerun. Players will have certain results on their card that will be determined by the ballpark effects. (> for singles determined by the ballpark effect and # for home runs determined by the ballpark effect)

On the ballpark list you'll see individual ratings for singles and homeruns for left-handed and right-handed batters. 20 is the friendliest to hitters, 1 is the least friendly. For an example, take Sportsman's Park in 1920. It is rated 14 for lefty singles, 14 for righty singles, 19 for lefty homeruns, and 4 for righty homeruns. This means that it is pretty easy for batters to hit a single in this park, relatively tough for righty batters in particular to hit homeruns, and VERY easy for lefties to hit homeruns. Maximize the talent on your roster by selecting a ballpark that plays to your team's strengths.
