Four-Seam Fastball– Castro fires a low-to-mid-90s four-seamer from a low 3/4 arm slot. The offering features good movement away from left-handed hitters and is a plus pitch.
Slider – The slider is above average at times with sharp late downward movement. Castro lives on the heater/slider combo.
Change-up – The change needs work and, according to reports, needs refining due to a hesitation in his delivery that may tip-off more advanced hitting.
Two-Seam Fastball – Scouts report that this pitch has some movement too but not as much as the four-seamer and with less downward movement. Tops out in the low-90s.
Reiffer says if Don Cooper can straighten out Castro’s command problems, Castro can become a member of the starting rotation.
The White Sox have signed Venezuelan righthander Luis Martinez for $250,000, the organization’s most expensive international signing in recent years.
Martinez, who turns 17 on Jan. 29, is 6-foot-4, 195 pounds and gets good downhill angle on an 88-91 mph fastball that has hit 92, an increase from the 84-88 mph velocity he was showing last summer around July 2. He has a projectable frame with long arms and plenty of room to fill out, so he should have at least a plus fastball in time. Martinez has a solid delivery, a high-70s curveball that is his best secondary pitch and he mixes in a changeup as well. …

Doug Padilla’s chat:
Q: This may be a tough question for you to answer. But, do you have any idea how highly the White Sox FO values sabermetrics?
A: They put a solid emphasis on it. Not saying it’s the deciding factor in all their moves, but they have a guy that works closely with KW to break down those numbers.
“Solid emphasis” would be better than I thought. Hopefully, Padilla is right. Another interesting note:
Q: Whats the biggest difference between Walker and the new hitting coach?
A: Walk was huge on mechanics, passing along what he had learned over the years from some of the greats in the game. He coached the mental side as well, but the word is that Manto will stress the mental side even more. Manto wants you in a great frame of mind to hit, then he will go to work on mechanics.
