The Phillies claimed pitcher Jerome Williams off waivers from the Rangers back on August 10. They needed starting pitching help, and likely didn’t want to go with Sean O’Sullivan for the 5th spot in the rotation.
Williams, however, didn’t appear to be all that good of an option at the time. He posted a 6.71 ERA for the Astros and Rangers up to that point in 2014. Many Phillies fans didn’t even know who he was, had never even heard his name before. We cleared that up, though.
But then something great happened. He was good. Not good-for-a-fifth-starter good, either. He posted a 2.83(!!!) ERA for the Phils in nine starts. The 32 year old averaged just over 6.1 innings and about 2.2 runs (including unearned) per start. For comparison, Cole Hamels averaged between 6.2 and 7.0 innings and exactly two runs per start, and A.J. Burnett averaged just under 6.1 innings and 3.58 runs per start.
Williams, who generally used his fastball and sinker the most, never really pitched that well, despite his outstanding ERA. His K% was just 16.5% and his BB% was 7.4%. League averages for NL starters were 19.5% and 7.1%. His K-BB% was 9.1%, with the league average being 12.4%. Many of his other stats were at or close to league average.
One thing that sticks out, however, was his BABIP. While he was surrendering around the league average in line drives, ground balls, and fly balls, the ones that were in play were turned into outs at a higher rate than average–his BABIP was .257, and the league average was .294. .257 was the 8th-lowest among NL starters with at least 50 innings pitched. Combine that with his solid (8.5%) HR/FB rate, and we’ve got a pretty good explanation for his great ERA, despite his average peripherals.
I don’t see how Jerome Williams can receive any other grade. He came to the desperate-for-starting-pitching-help Phillies and gave them all that they could ask for and way more. I would feel pretty comfortable saying that Williams’ performance-to-expectations ratio was the highest on the Phils. He was outstanding, and pitched himself into a new contract in Philadelphia.
