One guy that usually does pretty well and he is silver is Dennis Martinez. He has a high movement and is ‘cheap’. And Dierker has been 1.5+ WAR every season I’ve had him. Strasburg gold is solid almost every season for me as well. Hendricks low gold has been good as a fifth guy, but get used to low 4 era’s and have a faster hook or lower pitch count for him. He usually ends up strong at end of season for me. This might be different for you though in Gold or above, I’m still in silver.
I am targeting the 86 Keuchel, he has a high movement, but hes been selling pretty high. Also don’t forget some gold starters can actually do better as relievers in higher levels. I’ve tried Corbin and Paxton at relief and they’ve been good at silver level so far.
