A variety of reasons..............
1. Short left field wall, making for tougher decisions on singles hit there with a man on 2nd.
2. Being a park condusive to offense, puts more pressure on a 3rd base coach(so does a park that is just the complete opposite).
3. Lots of balls hit to death valley in center and right-center with a ton of nooks and crannies making a 3b coach's job tough to see where the ball actually is.
