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.
