As a result, speculation is that the Tigers will pursue free agent shortstop Stephen Drew, Bowden reports.
Iglesias, who has only four career home runs, hit .330 in 63 games for Boston before he was traded to Detroit. He hit .259 in 46 games for the Tigers, and .231 in 11 postseason games.
The 24-year-old is regarded as one of the game's top defensive shortstops.
Drew, 30, hit 13 home runs last season for the Red Sox, with another three in the playoffs. SI WIRE: Dodgers OF Carl Crawford will skip Australia trip due to upcoming birth of child
