Stubbs and Heisey need to stay down on the farm for the time being. If Hopper is an improvement (he is only OPSing .705 in AAA), it is a marginal improvement at best. I think you stick with Taveras until at least the All-Star break. WT by default it would appear. The toughest part is that Taveras is not even a good platoon candidate. For his career he actually hits righthanders a little better than lefthanders. Eek, aside from Gomes none of the Reds' outfield candidates have swung a very potent stick versus lefthanders in their careers.
I threw Keppinger in there just because. I still have no idea how a team that was going to struggle to score runs could not find a place for someone who has raked like that against LHP in his career.
