His ERA and his SIERA disagree by 1.18. The ERA is the harsh one — he has pitched better than his run prevention shows. SIERA is built from strikeouts, walks and contact, so it settles far faster than ERA does.

Against left-handed and right-handed batters

Neither his xFIP (0.14 between sides) nor his strikeout rate (1.1 points) moves much depending on the batter’s hand. That is worth knowing too: the read on his night has to come from somewhere else.

xFIP rather than SIERA by hand: FanGraphs does not publish SIERA in its splits. The two describe the same thing and correlate at about 0.95.
