As a baseball purist I hate dirt infields. We see them in tournament travel. I went to the source, the players. They say the dirt infields properly groomed provide a truer bounce than most grass fields. Then again, my son the commie likes playing on turf due to the true bounce and how fast he runs on turf (ran a 6.8 sixty on turf as a high school freshman).
The first time he stoled second on turf he slide ten feet past the bag. He was nearly ejected for coming into the second baseman so hard. He wiped out the fielder and kept on going. The ump did ask if he had played on turf before before deciding not to toss him.
