All SSS, but his splits are rather interesting. 1.50 gb/fb vs lefties, 0.67 gb/fb vs righties (hence the xFIP differences). Lefties hitting .287 against him, righties .216. Sets the table for a rather fascinating argument lol.
Some interesting things from looking at Brooks (ignoring the spring start):

Now according to Fangraphs, his changeup is (by far) his best pitch, but he doesn't throw it to lefties very often. So are his better results vs righties due to the change with xFIP throwing us for a loop, or is xFIP correct?
To muddy things even further (just because), his GB rate with the change is actually good... Regardless, it's all pretty SSS anyway.
