Bello's s Imaginary "September Fade"

He had 5 starts in September. The next to last was a day game on 4 days rest, a combo he had dealt with just twice, which means he hadn't the time to develop a between-starts routine as he had earlier done for the separate challenges of 4 days rest and day games. I'll run the numbers at the end and you'll agree that they were meaningless as a skill measure.

In is other 4 starts, he threw his change, sinker, and slider a total of 300 times resulting in 75 PA. (Actual numbers, not rounded!)

He allowed a .201 xwOBA and .242 wOBA. That's note a "fade," folks; it's a strong CY candidate's numbers.

Alas, he threw his four-seamer 89 times for 19 PA and had a .433 xwOBA and .696 wOBA.

Oops.

How did it fair before September? I'm excluding the 8 games where he struggled at day or on 4 days rest.

This is xwOBA, wOBA, starts, pitches, PA

.388 / .347, 4, 98, 21   May

.245 / .131, 5, 131, 31  June

.365 / .578, 6, 98. 22  July / August

Worst case is he junks the 4-seamer, but look at that June: 131 pitches and a .131 wOBA allowed.

His June 20 start, xwOBA, wOBA, pitches, PA:
