Dave Martinez will be announced as the new manager of the Washington Nationals after the World Series, a source told ESPN, confirming multiple reports.

As the rookie manager takes over in Washington, his three-year deal reflects a commitment new to the Nationals.
FanRag Sports first reported the news.

Martinez has agreed to a three-year deal with an option, the source told ESPN, confirming a report by The Washington Post. The value of the pact, which includes an option for a fourth year, has not been disclosed.

The Mets will name Indians pitching coach Mickey Callaway as their new manager, a source confirmed to ESPN on Sunday.

The news was first reported by the New York Post.

Callaway will replace Terry Collins, who stepped down as manager to take a position in the team's front office, after the Mets fell to a 70-92 record this season.

For the majority of his four seasons as a utility infielder with the Red Sox, Alex Cora wore No. 23. Nearly a decade later, the most relevant number associated with him will be 47.

Cora was hired Sunday as the 47th manager in Red Sox history, the team announced Sunday. After one season as the Astros' bench coach, he will take the reins of a young Red Sox team that won 93 games and a division title in back-to-back seasons under deposed manager John Farrell.

Cora received a three-year contract with a club option for 2021, a source told ESPN.
