(GOODYEAR, Ariz.) -- Michael Bourn is officially a member of the Cleveland Indians.

The team announced the signing Friday, a four-year deal worth $48 million. Bourn's signing now adds $117 million in guaranteed money that the Tribe has dished out this offseason to free agents.

Bourn, 30, was an All-Star with the Atlanta Braves last season and hit .274 with nine home runs and 57 RBIs.

The center fielder will remain in his familiar position with the Indians and is expected to bat lead-off. A threat on the base paths, Bourn has led MLB in steals with 257 since the 2008 season.

Bourn participated in the club's first full squad workout Friday morning and is scheduled to hold an introductory press conference with Indians general manager Chris Antonetti and his agent Scott Boras.

Boras said the signing was not a surprise due to Major League Baseball's new financial structure.
