There was (still is?) a thread about Cedar Rapids being "in a bind" due to their SP reaching an innings limit--all were under 70 innings pitched!MLB SPs need to go 162 innings to "qualify".
As the person who probably started the thread regarding the Kernels' dilema re starting pitchers bumping up against inning limits, I think we need to understand one thing. The approx 70 innings that the 3 lefties involved (Thorpe, Gonsalves and Batts) have thrown is a bit misleading.
Batts threw something like 100 innings at UNC-Wilmington this spring, so he's north of 160 IP on the year.
The official innings count on Gonsalves and Thorpe didn't start until June when they joined E'town and CR, respectively. They didn't spend April and May playing soccer. They were in Extended Spring Training getting regular work in live situations. They just don't keep public/official stats for those outings, so there's no way for the public to really know how many innings they went before their official seasons started.
I think it's probably safe to assume they each threwat least 20 innings per month, putting them both at somewhere around 100 innings on the season right now. That's a fair amount more than what they threw a year ago when they both split time between rookie league rotations and bullpens.
It's the additional workload this year over the innings put on their young arms a year ago that the Twins are closely regulating.
All of that said, I think you can usually tell when a young pitcher is hitting a wall and should be shut down. (see Berrios, Jose, Aug 2013) and none of these 3 pitchers seems to be laboring all that much at all their last few starts, to my admittedly amateur eyes. Thorpe's pressed a bit with his command and ended up walking a couple more guys than usual in each of his last couple starts, but that's been about the only notable thing I've seen with any of them.
Anyway, my point really was simply that you can't just go by official IPs for guys whose seasons didn't start until June. They were pitching somewhere before that.
