F-Rod as in Fraud

Francisco Rodriguez came in for the Angels tonight and had some ungodly stuff, fastball in the mid-90s and breaking balls that fell off the table. Mondesi (I think) swung at one ball that bounced seemingly before the plate. He did give up two runs that are still earned even with Gil's error (Scorers never seem to charg players with an error for not turning the double play but for a throwing error where the runner advances. The scorer charged Mondesi with an error on a play in which Soriano nearly collided with him. Why not charge a middle infielder who has plenty of time to complete a double play but instead syumbles around the bag and fails to get the ball out of his glove with an error?)

My question is how Rodriguez is even on the Angel's playoff roster. He made 5 appearance from September 18 on and was not on the roster on August 31. The rule is that the get to add a player for ones on the 60-day DL. The Angels have pitcher Steve Green on the 60-day since March 11. I can see Arizona being able to replace Gonzalez and Anderson on their playoff roster with a post-Aug. 31st player--they got hurt after the deadline. But how does a mid-March injury have anything to do with who is allowed to play in a playoff series. The roster should reflect the team as it was constituted during the regular season. Veteran reliever Al Levine gets dropped and a 20-year-old rookie gets added. It doesn't seem fair.
