I could see Fiers and Nelson piggybacking. Nelson will likely have to skip a start or two to keep his innings from getting too high. No one else really has that concern. One wildcard is Peralta's chase of 20 wins. He has 7 starts left, but could start on the last day of the season, if they pitch him every 5 days and skip someone with the days off in September. I could see them giving him that extra start if he has a chance at 20 wins. The other wild card is whether the last games of the season are fighting for the division, or resting up and lining up starters for the playoffs.
