We've all felt that sinking feeling when the White Sox are about to face a starting pitcher that a major league offense should typically feast upon. There's been plenty of games we can point to in which the White Sox bats have gone limp in an aggravating affair against an underwhelming hurler. You know the types:
- Soft-tossing lefties with underwhelming stuff and peripherals, like Bruce Chen and Tommy Milone
- Random call-ups and rookies from the minor leagues without an impressive pedigree that the White Sox have never faced before
- Jeremy Guthrie
- Guys with longer track records might be placed in a different category than that implied by their career-long body of work (Sonny Gray is an example). However, to the extent that there's something particularly "wrong" or "right" with the way they happen to be pitching this year, we want to reflect that.
- This method leaves open the possibility of fringe guys with short major league stints being categorized somewhat improperly based on a "hot" few games. I don't think that this applies to any pitcher in the study.
- "Good": FIPRA less than 3.50
- "Above-Average": FIPRA between 3.50 and 4.25
- "Below-Average": FIPRA between 4.25 and 5.00
- "Disaster": FIPRA greater than 5.00

Jason Kipnis is a good hitter! It seems we can conclude that the White Sox don't have any significant problems hitting the worst starting pitchers in the league.
....Or can we?
How does the rest of the league fare against pitchers from that group? If we take the "Disaster" pitchers' triple-slash lines allowed against the league as a whole and weight them based on at-bats (or plate appearances, for OBP) against the White Sox, what sort of result would we expect? I looked up the numbers for each pitcher in that category and the weighted-average line allowed is...
- .290/.354/.492 (Ian Kinsler)
....Or do they?
What we have to remember here is that the White Sox offense itself is below-average. They have a wRC+ of 89 and slash .251/.316/.401. The American League average is .260/.324/.427. That right there accounts for the bulk of the discrepancy and the rest is a relatively small amount of variance for slash lines against the most volatile pitchers in the major leagues. Of course the White Sox hit bad pitchers a little worse than league average; they're worse at hitting than league average.
It's extremely frustrating to watch your offense look helpless against Cody Anderson, or fail to pounce while Jered Weaver just sort of lobs it in there, or seem like a oasis in the desert to guys like Guthrie or Chen for years. Fans look back on games like these and imagine they occur with disproportionate frequency because the frustration makes them memorable. When the White Sox jump all over Matt Boyd or blast Luis Severino back to Triple-A Scranton or obliterate former nemesis Tommy Milone, it goes forgotten because these pitchers are bad and the result doesn't stick out as remarkable.
Therefore, there's some cognitive bias at work when our minds get the impression that the White Sox struggle more than usual against weak or unknown pitchers. Sometimes a pitcher that isn't very good will have a strong outing against your team, particularly when your offense is below-average. Maybe he'll have better movement on his pitches, maybe his command will be randomly on point that game, or maybe poor BABIP luck will combine with a few hitters having an off day to keep the offense quiet. That sort of stuff will happen over a 162-game season.
Many have tried to assign a reason that the White Sox occasionally fail to hit pitchers that should trigger chop-licking rather than dread. Some blame the hitting coach, others get mad at Robin Ventura for not having the team in the right mindset, and others suggest bad advance scouting (my personal least-favorite narrative). The real culprit is the randomness of baseball, and other teams have to deal with it too. Just think back on how Mat Latos tortured four opposing teams before reality caught up to him.
Therefore, White Sox fans can comfortably go into a matchup against a Weaver, a Milone, or Joe Minor Leaguer expecting better-than-usual results. While success is never a guarantee, we shouldn't invent a cause for past failures and let it guide our feelings towards the next game. There's nothing concrete to point to, and any reason for concern about facing these pitchers is just in our heads.
