Definition. SIERA quantifies a pitcher's performance by trying to eliminate factors the pitcher can't control by himself. But unlike a stat such as xFIP, SIERA considers balls in play and adjusts for the type of ball in play. For example, if a pitcher has a high xFIP but has also induced a high proportion of grounders and pop-ups instead of line drives, his SIERA will be lower than his xFIP.

SIERA baseball stands for Skill-Interactive Earned Run Average is another advanced stat that measures pitching. SIERA builds on FIP and xFIP by taking a deeper look at what makes pitchers better. As FanGraphs describes, “SIERA tells us more about the how and why of pitching.” In terms of being predictive, SIERA baseball seems to have the edge over other pitching metrics.
The skill set looks like Dallas Keuchel, so he’ll probably be more valuable in real baseball due to the mediocre strikeout rate, but he should remain a solid asset for as long as his control remains decent. Dylan Bundy has posted a SIERA just below four before, so this isn’t completely out of nowhere.
