Got to the CPX today and ... whaaaaa?  I didn't put the movement chart in last night?  What a feeb... here y'go amig-O's:

Brooks called that blue pitch a FOUR-seam fastball - on what basis, I don't know.  4-seamers are fast; 2-seamers sail kinda like wiffleballs, more slowly and with more break.  

These pitches averaged 93.2 MPH for Erasmo last night, so presumably the pitches were getting classed as 4-seamers because they were all within 1-2 MPH of his very maximum speed on the night.  

His velocity is the most consistent I have seen; he threw 29 of 30 fastballs within a tiny 2.2 MPH band of the chart.  That's a good thing as far as his physical attributes, but can be a bad thing as far as pitcher timing.

............

G-Money sez,

I said last fall that I thought he needed a third pitch if he wasn't gonna throw his curve.  Well, his curve looked fine last night, his velo differential seemed to be in a better delta and the movement was back on his FB and change, which was lacking at altitude.  He'd be a horrible pitcher for the Rockies. 

In the heavy air of the NW? 

I'd be very interested to know:  how much does Colorado affect the run on a fastball?  Maybe Erasmo will get a Sal Maglie effect.  The Barber said that his career turned around when he learned to snap off a curve at altitude in Mejico...

Tell you something else, though.  I was watching the charts, during the game, and in the first two innings, Erasmo's FB and change were swerving 15 inches! armside -- fully the equal of anything Doug Fister ever threw.  In the 3rd and 4th, the swerve settled back into normal ranges.

Maybe the finger-snap and RPM are things that Erasmo is just now learning.
