I see this a lot, but it actually has little to do with expanded roster. In fact, he actually crunches playing time. Grandal catching every day, no rest for any of the starters really. Uses the same, top 7 or 8 relievers over and over. Hes not using 35-38 guys, he's using 25. And really, 20 as much as humanly possible. September has been about the 3 pitching acquisitions, Suter and Hiura coming back, and the team as a whole putting their game face on, and that part is definitely due to CC. But Suter's availability (8 games, 17.1 innings) was in addition to the other arms that had been in the pen. Same with Woodruff's 4 innings. Plus the "unused" pitchers of Williams, Williams Faria, Burnes and Nelson add up to 15+ innings. Even if most of them are mop-up situations, it still saves the other arms for higher leverage situations. So saying CC does well with extra arms available is accurate. However it is also reasonable to say CC gets the most out of the staff during the regular season. It is also true that the whole staff is doing vastly better this month, but it is impossible to know how much was just from player improvement and how much increased rest helped.
