The things with bullpen arms is that there, these days, are two kinds. You have guys who throw 95 and “slider specialists.” Are all “slider specialists” bad, well, no. But they’re called slider specialists because they rely on movement, they rely on confusing the hitters and getting swings and misses. Once that stops working, they fall apart. Guys like Cody Stashak and Caleb Thielbar are a prime example of this, batters have both of them figured out. The league is more statistics these days so batters have them figured out. That’s why it’s generally a better idea to build bullpens (and a pitching staff as a whole for that matter) around guys who throw 95, because they’re less prone to falling apart at the seams. But bad command will kill any pitcher. If a guy who throws hard (Rogers, Robles, Duffey, Alcala) loses his command he will fall apart. But the thing is “95” guys have two ways of falling apart: 1. Losing velo (which happens with age) and 2. Losing control. Slider specialists have three ways of falling apart: 1 and 2 are the same but a 3rd is them getting figured out. More on Colome: His K% was down quite a bit last year, but he hasn’t lost velo. It’s not like he’s a “softball pitcher” either, because his fastball does average 94 (which is about 95). But he has no command. I don’t want to see him past the 6th in a close game until he fixes it, or until he’s DFA’d.
