PL on RotoGraphs: The Curious Case of Trevor Williams
It’s time we talked about the pitcher that just doesn’t make sense.
Trevor Williams is an anomaly. We like to focus on peripheral numbers to get a better sense of how a pitcher is performing and Williams’ under-the-hood numbers since July 2018 paint a mediocre arm:
Trevor Williams’ Last 17 Starts
|SIERA||Strikeout Rate||BABIP||LOB Rate||HR/FB Rate|
Yet across seventeen starts since July 11th, Williams is flaunting two ridiculous numbers:
1.60 ERA & 1.08 WHIP
Williams’ repertoire consists of a seemingly mediocre 91 mph fastball, a changeup that returns a 7% swinging-strike rate, and a slider with a career middling .260 BAA. These are pedestrian numbers for a three-pitch mix, yet 100+ frames have returned only 18 earned runs.
It doesn’t make a lick of sense and I love when something doesn’t make sense. It means there’s something interesting to talk about.
So let’s talk about it.
