Underachieving White Sox Drop Keuchel and Lose Anderson as Well

The White Sox have spent the first two months of the season meandering around .500 due to injuries and underperformance. Over the long holiday weekend, they offered reminders of both issues, first designating struggling starter Dallas Keuchel for assignment and then losing Tim Anderson to a groin strain. With Lance Lynn likely to return from a knee injury within the next couple of weeks, the rotation should remain a source of strength for the defending AL Central winners, but Anderson’s absence looms large in a lineup that’s missing several other key players and struggling to score runs.
The 34-year-old Keuchel had pitched poorly this season, with a 7.88 ERA and 6.20 FIP. He’s averaged just four innings per start, walked hitters at the same rate as which he struck them out (12.2%), and served up a career-high 1.69 homers per nine despite being one of the game’s top groundballers. He appeared to be righting the ship with a pair of solid starts against Red Sox and Yankees earlier this month, allowing two runs in 11 innings against the pair on May 8 and May 14, respectively, but both teams pummeled him upon getting a second look, with damage totaling 12 runs in six innings on May 21 (Yankees) and May 26 (Red Sox).
The White Sox signed Keuchel to a three-year, $55.5 million deal in December 2019, and he pitched well enough the following season (1.99 ERA, 3.08 FIP, 1.8 WAR) to place fifth in the AL Cy Young voting. But last year, even while the team ran away in the division race, he was little more than an innings-eater, pitching to a 5.28 ERA and 5.23 FIP in 162 innings and being left off the Division Series roster. Last year’s Statcast expected numbers (xAVG, xSLG, xwOBA, xERA) were actually worse than this year’s numbers:
Year | BBE | EV | Barrel% | Hard-Hit% | xAVG | xSLG | wOBA | xwOBA | ERA | FIP | xERA |
---|---|---|---|---|---|---|---|---|---|---|---|
2018 | 661 | 87.3 | 4.1% | 32.8% | .246 | .362 | .305 | .293 | 3.74 | 3.69 | 3.60 |
2019 | 348 | 88.8 | 5.5% | 38.5% | .261 | .423 | .327 | .329 | 3.75 | 4.72 | 4.82 |
2020 | 198 | 86.8 | 4.0% | 31.3% | .278 | .394 | .249 | .317 | 1.99 | 3.08 | 4.27 |
2021 | 558 | 88.3 | 8.9% | 39.7% | .302 | .493 | .356 | .372 | 5.28 | 5.23 | 6.15 |
2022 | 124 | 88.3 | 8.9% | 34.7% | .280 | .445 | .411 | .349 | 7.88 | 6.20 | 4.48 |
Looking back, Keuchel’s 2020 expected numbers contained some warnings that his season wasn’t nearly as good as his ERA or even his FIP suggested. His results on his cutter, in particular, were way out of line with his expected results:
Year | % | AVG | xBA | SLG | xSLG | wOBA | xwOBA | Whiff |
---|---|---|---|---|---|---|---|---|
2018 | 15.5% | .231 | .235 | .398 | .356 | .289 | .279 | 21.7% |
2019 | 19.8% | .290 | .273 | .565 | .514 | .387 | .366 | 16.3% |
2020 | 30.9% | .203 | .328 | .246 | .517 | .241 | .393 | 21.4% |
2021 | 24.4% | .329 | .314 | .518 | .508 | .381 | .373 | 17.4% |
2022 | 17.2% | .419 | .300 | .935 | .633 | .589 | .403 | 21.5% |
Note that those odd 2020 expected results, which no doubt owe something to the small sample, bore much closer resemblance to his xBA and xSLG for the following year than to his actual AVG and SLG from ’20. Long story short, Keuchel came out smelling like roses when his overall wOBA allowed was 58 points below his xwOBA, but when his barrel rate more than doubled and his wOBA rose 62 points above his xwOBA in 2022, he was out of a job.
