I think Perez will easily have the most saves in the next 3 yrs. And Gregg will be traded this offseason or at the deadline. He's a FA at the end of the year and probably not closer material when he hits FA.
I didn't follow Zumaya at the end of the season, but even though he had a 3.47 ERA he also had a 5.78 FIP with 22BB in 23IP for a 2.00 WHIP. He's obviously isn't back yet from his rather serious injury. Especially considering that he missed the month and half of the season. I don't think he'll be a closer at all in '08 and they sign or trade for a closer.
for sure Perez it looks like he will step in for the Cardinals. Gregg is now in Chicago and will likely be just a setup man. Zumaya who knows if he will be great again or not. I go Perez viewtopic.php?t=363643
