The 3B next to Arod should have had 35 DP's in an average season. They ended up with only 15 DP's for the year. The balance were picked up by Arod.

The game decided that some of the balls in between the SS and 3B were taken by the SS instead of the 3B and converted into a DP. What may look like an extra DP being made is in reality just a DP being assigned to the SS instead of the 3B.

Make sense?
