It's an Insider article, so I can't post it obviously, but it's pretty interesting. Basically, Olney sets forth that the Reds have the easiest remaining schedule of all teams in the NL who are contending. The Pirates have the 2nd easiest schedule remaining (in the NL and our division), but the Cardinals by far have the hardest remaining schedule of NL Central teams and one of the hardest of all contending teams. Reds/Pirates/Cardinals all have a tough end to the season.
Also, it was mentioned during the game today that the rotation out of the break against the Cardinals will start out with Latos pitching 1st, Leake pitching 2nd, and Cueto pitching 3rd, to give him some extra rest. They didn't say, but I would imagine Arroyo would be 4th and Bailey 5th.
