Matt Cain. I'd take Stras myself but the pundits say it's Cain, Dickey is fading.
Fangraphs WAR says Greinke and Strasburg
xFIP says Strasburg and Greinke
ERA says Dempster and Dickey
K/9 says Strasburg and Gio
K says Strasburg and Dickey
FIP- says Strasburg and Greinke
WPA says Dickey and Cueto
I don't see Matt Cain's name in there.
