In 2019, despite the success of the New York Yankees‘ season (reached the American League Championship Series), the ballclub succumbed to a great number of injuries. New York had 30 players experience 39 total stints on the injured list. Overall, they had players spend a total of 2,433 days on the injured list, which set a new major-league record.
You can make the argument that injuries are a case of bad luck. But when a team’s health is this bad, any well-run organization would investigate and make some changes. Luckily, for fans, the Yanks are a well-run team and have thus switched out their training staff.
