Outfielder Michael Bourn will be introduced as the newest Indian at a press conference Friday after passing his physical Thursday. The Indians signed Bourn to a four-year, $48 million contract on Monday.

Bourn, who will wear No.24, will be the Indians center fielder and leadoff hitter. He is the second big free-agent signing of the offseason for the Tribe. In December, they signed Nick Swisher to a four-year, $56 million deal. Swisher, who will play first base, left the team Thursday to attend the funeral of his mother in Columbus. It is not known when he'll return.

The Indians have spent $117 million this winter on free agents Bourn, Swisher, Brett Myers and Mark Reynolds. The deals for Swisher and Bourn are the biggest free-agent signings in franchise history.

Bourn, who took part in the Tribe's first full-squad workout Friday, can vest a club option for 2017 worth $12 million if he gets 550 plate appearances in 2016 and passes a physical at the end of the year.

Last year, Bourn hit .274 (171-for-624) and set career highs with nine homers, 57 RBI and 70 walks for Atlanta. He stole 42 bases in 55 attempts. In the previous three years, he led the National League in steals with 61, 52, and 61 steals.

Bourn, 30, is a career .272 (820-for-3,015) hitter with 125 doubles, 45 triples, 22 homers and 215 RBI in seven seasons with Philadelphia, Houston and Atlanta. He has stolen 276 bases in 340 attempts (81 percent) and has scored 459 runs in 871 runs.

Defensively, Bourn is considered one of the best center fielders in the game. He's won two Gold Gloves and went to the All-Star game in 2010 and 2012.
