"Tigers are interested," the source said. "Not sure how serious the interest since Inge's injury is not as severe as they thought."
Lowell has been on the DL with a right hip strain since June 23 and is rehabbing with Triple-A Pawtucket. He served as the PawSox's DH and went 1-for-5 on Thursday. He played third base on Saturday and is scheduled to play first base on Sunday.
Boston manager Terry Francona has been speaking with PawSox manager Torey Lovullo and the reports on Lowell have been good.
"Torey said [Lowell] took a bunch of ground balls at third the other night, and actually looked really good," Francona said. "He moved around real well and threw real well."
Lowell is batting .213 with two homers and 12 RBIs in 31 games for the Red Sox this season. He's made it no secret of his desire to play every day and would welcome a change of scenery.
