In the postseason, though, it had been a different story. From 2008 to 2018, Kershaw appeared in 30
postseason games and pitched 152 innings. His ERA, though, was only 4.32, or nearly two runs worse
than his career regular season performance. And in none of these years did Kershaw’s Los Angeles
Dodgers finish the postseason as World Series champions.
Failing in the playoffs doesn’t directly impact player’s compensation. Player salaries in professional
sports are only for the regular season. So, before the playoffs started in 2018, Kershaw had already
collected his $35.6 million. Given this point, perhaps Kershaw’s regular season brilliance fully justifies
his salary. Then again, maybe people should expect a player as great as Kershaw in the regular season
should be more like Bob Gibson when the season ends.
From 1964 to 1973, Gibson was very much like Kershaw in the regular season. Across these years,
Gibson won two Cy Young awards, one league MVP, was named to seven mid-season All-Star games,
and won nine gold gloves. In the playoffs, though, Gibson was equally amazing. Prior to 1969, the
postseason only consisted of the World Series. In 1964, 1967, and 1968, the the National League was
represented in the World Series by Gibso n’s St. Louis Cardinals. In those three s easons, Gibson
pitched in nine World Series games. In eight of these, he pitched a complete game. He also threw
two shut-outs and had a postseasons ERA of 1.89. In addition, Gibson’s Cardinals won two world
championships and each time this happened Gibson was named World Series MVP.
When we consider regular season and postseason performance, one could argue that Gibson was a
bit better than Kershaw. At least, th at is the story told by the statistics we use to track on-field
performance. If we consider player pay, though, Kershaw completely dominates Gibson.
As given in Table 1, Gibson was only paid $30,000 in 1964. Although his pay generally increased in
each of the next eleven seasons, this was not always the case. For example, after the 1969, 1971, and
1973 seasons, Gibson’s annual salary was not changed. In an era of relatively high inflation, that means
Gibson, in real terms, was taking a pay cut despite posting statistics that suggested Gibson was one of
the top pitchers in MLB.
When we consider all twelve seasons, we see that Gibson was only paid $1.3 million in nominal
terms and only $8 million in 2018 dollars. In contrast, Kershaw was paid more than four times this
amount just for the 2018 season.
Once again, both Kershaw and Gibson rank among the all-time pitching greats. So on-field per-
formance simply cannot explain the large observed difference in pay. To understand the salary dis-
crepancy, we have to focus on the nature of the labor market each player faced.
1. Major League Baseball’s Unusual Labor Market History
Kershaw agreed to a 7-year, $215 million contract with the Los Angeles Dodgers in 2013.
this deal was extended for three seasons.
The extension not only added years to Kershaw’s contract, it
also increased his annual pay.
With both deals, the Dodgers faced a choice. Either the team reaches a contract agreement with
Kershaw or watch Kershaw play out his contract and then watch as the remaining teams in MLB bid
on his services. In other words, alt hough Kershaw was only negotia ting with one team, if those
negotiations broke down eventually, Kershaw would have an opportunity to negotiate with many
