Hi, I'm Matthew from Fun Facts Warehouse and my wife's at it again! She said, "Matthew, we're overstocked on fun facts in both locations and this stuff has got to go"! Please help me get her off my back and read this fun fact. Save big time with quick facts, only at at the Fun Facts Warehouse!
Relief pitchers in 2012 with at least 100 batters faced, sorted by strikeouts per net walk (walk + hbp - ibb)
1: Shawn Kelley, 7.2
2: Craig Kimbrel, 6.8
21: a bunch of people
77: more people
128: bad pitchers
218: the Cubs
Shawn Kelley has 36 strikeouts and just five unintentional walks this season. Craig Kimbrel and Aroldis Chapman have both struck out nearly half of all batters they've faced*, but they've both walked significantly more than Kelley has as well. I don't claim Kelley is the better overall pitcher, strikeout-to-walk ratio isn't the be-all of pitching metrics, but it is very important and it's cool to know that currently a Mariner is the best at it.
*Side note: holy ghosts!
By the way, not from 2012, but worth mentioning:
2011, Sergio Romo, San Francisco Giants, 70 strikeouts, 4 walks
2010, Cliff Lee, Seattle Mariners, 89 strikeouts, 6 walks (as a starter)
