Bourn arrived at Cleveland's complex on Thursday afternoon to undergo a physical, representing the final step in the completion of a four-year contract worth $48 million. The Indians are expected to hold a news conference to officially announce the signing at 3 p.m. ET on Friday.
"He just walked through the doors. I just stopped and said hello," Indians manager Terry Francona said during his sit-down with reporters on Thursday. "As long as he gets his medical stuff done, he'll work out [with the team on Friday]."
Bourn's contract will include a vesting option worth $12 million for the 2017 season. The option will kick in if the 30-year-old center fielder achieves 550 plate appearances during the 2016 campaign, and then passes a physical following it. Bourn has averaged 677 plate appearances in each of the past four seasons.
Last year, Bourn hit .274 with a .348 on-base percentage and a .391 slugging percentage in 155 games with the Braves. He established career bests with nine home runs and 57 RBIs, and added 26 doubles, 10 triples, 42 stolen bases, 70 walks and 96 runs scored for Atlanta.
Cleveland will lose its third pick (69th overall) in the First-Year Player Draft -- the fifth pick in a sandwhich round between the second and third rounds -- for signing Bourn. The Indians lost their second-round selection for signing free-agent Nick Swisher. The Tribe's first pick (fifth overall) is protected.
