Apparently they've been trying to work Hatteberg and Womack (ugh) into the lineup. Dunn was pretty much slated to start in LF from the get-go since he's rather defensively unsound...well, pretty much everywhere. However, that deficiency can be minimalized with him in LF. Pena demanded to be traded earlier in the season if the Reds had no plans of playing him regularly, so that didn't help his case very much. Their offense is still pretty strong with this trade, but with WMP's upside, you'd think they might have gotten something better out of it. Arroyo's career ERA against the NL is over 5, as memory serves me, and tends to be more of a flyball pitcher than a groundball kind of guy. This might turn out well for them in the end...but my gut says otherwise.
