Because I think Left Field isn't an issue and that there are more than half-a-dozen solutions that will play Left Field well in 2009. There's no reason to trade away any pitching for a Left Fielder. There are only about 730 plate appearances available in Left Field and that can easily be divided among 7 players throughout the season. Those 7 players combined should also be able to produce above average defense in Left Field as the average Left Fielder defensively (Adam Dunn) is poor, at best. Offensively, the total of those 7 players should be able to collectively produce average results by the end of the year. Average results is fine for one season when the Defense is going to be above average and the pitching is going to be above average. These seven players are will do more of the little things that Adam Dunn couldn't do to win ballgames.
Seeing that Walt Jockety hasn't obtained a starting Leftfielder yet reassures me that he continues to see the state of the REDS exactly as I do...and that's a good thing.
Come September 2009 (8 months from now), Alonzo should be starting at 1st Base, and either Votto or Encarnacion should be starting in Left Field. There's no reason to have some other guy clogging their developments, especially at the cost of some pitching that we currently have on our team.
