How Hurt Was Carter Kieboom During the 2020 Season?

During the 2020 season, a strained groin could explain why Carter Kieboom did not perform well during the season.

Steven Mears from (Twitter link) broke some news, stating that according to “A #Nats source told us on a condition of anonymity that Carter Kieboom played on what was thought to be a strained groin during the 2020 season and it turned out he was playing with a GROIN TEAR which explains the lack of power, hitting struggles, issues running, etc.” stated: “It was known that Carter Kieboom had a groin strain as the 2020 season opened from a report from Jesse Dougherty of the Washington Post. But the report also said, ‘the injury evidently only hurts when he moves laterally, so he’ll be able to hit and run the bases.‘”

Did the Washington Nationals mis-diagnosed the severity of the injury?

Mears followed up on this tweet by saying that “Carter is 100% healthy now per the source. Expect him to be a new kid in Spring Training.”

While we have no reason not to believe Steven Mears from Talk, if true, this would explain a lot about Kieboom’s lack of performance during the shortened 2020 Major League Baseball Season. It would also explain why Mike Rizzo and Dave Martinez have confidence in Keiboom’s upcoming season abilities.

According to, “A groin pull — or groin strain — results from putting too much stress on muscles in your groin and thigh. If these muscles are tensed too forcefully or too suddenly, they can get over-stretched or torn.

Groin pulls are common in people who play sports that require a lot of running and jumping. In particular, suddenly jumping or changing direction is a likely cause. Groin pulls often appear in people who play soccer and football, and they make up about 10% of all injuries in professional hockey players.”

Groin pulls are often divided into three degrees of severity:

  • 1st degree: Mild pain, but little loss of strength or movement
  • 2nd degree: Moderate pain, mild to moderate strength loss, and some tissue damage
  • 3rd degree: Severe pain, severe loss of strength and function due to a complete tear of the muscle

During the 2020 season, according to stats provided by Baseball, Kieboom’s performance was lackluster. Kieboom had only 99 at-bats, which only yielded 20 hits, no home runs, nine RBI’s, and a Batting average of .202, and a slugging percentage of .212

His 2020 performance raised serious doubts among many observers of Kieboom’s hitting performance and as a prospect. However, both Rizzo and Dave Martinez have publically shown their confidence in Kieboom; this could be why. In an end of the year press conference Dave Martinez said: “I talked to him, and I told him, “Hey, you’re our future third baseman, and the future is now. So you’ve got to come to spring training, be ready to go and the job is yours, but you’ve got to earn it, He knows that. Moving forward, hopefully he comes to spring training ready to go.”

In September of 2020, Carter Kieboom underwent X-rays to address swelling in his contused left hand, and afterward, his season ended.
