So I have only had the chance to throw a couple pens so far into our season. Today I threw a bullpen, 20 pitches, switched with a pitcher and he threw 20, then came back to me and I threw 20, then he threw 20. The first 20 felt great, no issues, good command, throwing 82-84 mph, just couldn’t find my curve.
Then I waited.
I got on the mound to throw my second 20, and my arm was just a lot stiffer, I felt as if I was throwing 2-3 mph less, my arm felt physically tired, and by the end of the second set I was having issues locating.
If I throw straight through though my bullpen without a break my velocity and command remain there. How do I keep this from happening in a game between innings?
