There are several difference between the photo of Caleb from Fall Ball (blue) and Spring Ball (green). One stood out to me more than the others. What stands out to you? (mine has nothing to do with baseball)
Yes, it’s the missing SpiBelt, and thus missing DexCom receiver. It’s around Coach Dave’s (dad’s) neck. Yet another example of the amazing range of DexCom G4!!!
This is Caleb... 
No SpiBelt!?! Great form in both pics!
Winner!
No pouch around his waist! He makes an intense face just like my son! Love it!
Winner again! 😉
My husband would tell you that the position of his left arm is different – I noticed the missing pouch immediately!!
Yet another winner – it’s hard because of the shadow, but it’s always stood out to me.
4 seam fastball vs. change up 🙂
Haha. I don’t even know what that means. 😉
