The hard thing with bullpens sometimes is that you're giving it all you've got that day, but you're not fresh. You've pitched two days prior, so your body is ready to throw, but you have a short window of time to work in because a lot of time when you go out there and throw a bullpen, if you get too many pitches deep, like 30, 35 pitches deep, your body is tired, essentially. You're working differently than you would in a game, so your window of work is pretty short, and so that's why tools like Rapsodo exist, things like that — so you can really hone in and take a lot of the guesswork out of things. When I throw a pitch, you can see the spin-axis. You can see the way it's coming out of my hand, not just an eye-test version, but what the ball's actually doing?
