Overly Tired Arm

So last couple of years at the beginning of the season when I throw for the first time 50+ pitches, my arm just feels completely zapped of power the next time I throw. I’m not sure what causes it but it seems my arm feels drained for sometime and I basically lose my velocity for a good part of the season. Anyone else ever have this problem?

Could be you’ve pushed yourself too much too soon.

Could also be the dead arm phase, but if you’re velo isn’t coming back I’d be thinking you’re not giving yourself enough rest and are just compounding the problem.
