If You're Hardcore: Snider and Gamel good pickups

September is finally here, and that means it's time for those in keeper leagues to do their homework, regardless of position in the standings. In a four-part September series, If You're Hardcore helps you break down all the call-ups, from potential 2009 keepers to players who might see enough at-bats to have an effect down the stretch. Each player has been assigned a letter grade for each of three factors: his ability to contribute this September, his chance of being useful in 2009 and his long-term outlook.
