As “Clayton Kershaw can’t pitch in the playoffs” narrative resurfaces, a reminder

33 Comments

Dodgers ace Clayton Kershaw couldn’t make it through the fifth inning of Sunday night’s start against the Astros in Game 5 of the World Series. He gave up six runs on four hits and three walks with two strikeouts on 94 pitches. That sent his career playoff ERA, now across 23 appearances and 118 innings, up to 4.50.

Prior to Sunday’s start, Kershaw had pitched well this postseason, carrying a 2.96 ERA in four starts. And most of the damage came in his Game 1 start in the NLDS against the Diamondbacks, when he surrendered four solo home runs. His World Series Game 5 start, however, resurfaced the old “Kershaw can’t pitch in the playoffs” narrative.

It’s true: Kershaw’s stats in the postseason aren’t good. But there’s a bit of context that’s often left out of the conversation, which is that relievers that have come in after Kershaw have also not done a great job. Following Jose Altuve‘s three-run home run off of Kenta Maeda in the fourth inning, on which two of Kershaw’s runners scored, Dodgers relievers had allowed 10 of 16 of runners inherited from Kershaw to score. That’s a 62.5 percent rate of failure, or a 37.5 percent success rate. Since Kershaw debuted in 2008, the major league average strand rate (success) for relievers has ranged between 72.8 percent and 75.2 percent. In other words, Dodgers’ relievers — when relieving Kershaw — have been half as effective as a major league average reliever.

Here’s the full list:

If the Dodgers’ relievers had done their jobs perfectly, stranding all 16 of runners inherited from Kershaw instead of six, Kershaw’s postseason ERA would be 3.28. Kershaw’s mental fortitude wouldn’t even be a topic of discussion. Of course, one would argue that Kershaw shouldn’t have allowed those runners to get on base to begin with, but the purpose of a bullpen is to sometimes bail out a starter once he gets into a pickle — especially in the postseason. Dodger relievers — notably Pedro Baez — have done an absolutely terrible job of backing up Kershaw over his career and that needs to be remembered when people bring up Kershaw’s perceived postseason issues.

Ketel Marte shut down with back injury

With just over a week left in the regular season, the Diamondbacks have elected to shut down infielder/outfielder Ketel Marte. Marte has been dealing with some lower back inflammation and stiffness over the last few days; on Friday, the team revealed that he was diagnosed with a stress reaction as well.

It doesn’t look as though the injury will compromise Marte’s 2020 campaign, but as Craig noted on Wednesday, his absence will likely have some effect on his NL MVP candidacy. The 25-year-old will wrap his first All-Star season with a .329/.389/.592 batting line, 32 home runs, a .981 OPS, and a staggering, career-best 7.1 fWAR through 628 plate appearances.

Marte told reporters Thursday that the back pain had been an issue “for the past two months,” though he didn’t comment on the severity of the injury. Despite his ability to play through the pain since July, the issue has clearly escalated in the last week or so. Although the loss of their most valuable contributor may have a negative impact on the D-backs’ chances of competing in the postseason, it’s undeniably a wise move to let Marte recuperate rather than pushing him to play for another week and running the risk of further injury.

Entering Friday’s series against the Padres — their last road series of the regular season — Arizona still has a sizable gap to close in order to earn one of two NL wild card spots. They’re five games out of postseason contention, with the Nationals, Brewers, Cubs, Mets, and Phillies ahead of them.
