Some speculation that Reds might want to trade Simon in any deal for offense.
If so, today's outing against the DBacks could be important.
It's only one outing, but buyers are looking for short term results so they may be influenced by today's performance.
Also the trade deadline could put more pressure on Simon, so it could influence how well he does.
Provides an interesting sub-plot to an otherwise fairly typical late July game against the DiamondBacks.
