They were carrying 7 relievers most of the season and 13 position players.

Depending on how they use their bullpens and how long they expect their starters to go, everyone carries either 11 or 12 pitchers these days.

Lidle seems to be a guy that can go 6 or 7 if he has halfway decent stuff on a given day, so if Torre figures that the only "5 inning pitcher" he has is Wright, maybe he can get by with only 6 relievers.

And since the bench is much stronger now, it definitely could be worth the trade-off.

But they still have to find a 6th reliever to replace Ponson, who seems to no longer have a role.
