Alex Vesia missed the World Series due to a deeply personal family matter involving his wife, Kayla, who was expecting their first child. The Dodgers announced his absence to support him through this personal situation, and leadership stressed the decision was made to relieve pressure and prioritize the family.

[Tours and statements from team leadership and multiple reports confirm this context and rationale.]
