Well, that's fair enough, but I still think the 105-110 OPS+ Bohm is probably the Phillies' best option, as there's also no reason to think Turner would be good defensively at 3B, nor to think Sosa would hit as the full-time shortstop.
But mostly there's just too many other holes, both in the OF and in the collection of RHBs, to not try and squeeze what they can from Bohm and Turner for a couple of more months. The current W-L record is still no reason to panic.
