Red Sox manager Bobby Valentine was asked before Thursday's game against the Twins if Lowe is on the club's radar.
"If he's available and someone might think he can help our situation, I'll bet you he's being talked about and evaluated," Valentine said.
Lowe, 39, pitched for the Red Sox for eight seasons and helped the club to a World Series championship in 2004, his final year in Boston. Since then, he's bounced around between the Dodgers, Braves and Indians. Lowe was 8-10 with a 5.52 ERA in 21 starts this season.
"I haven't seen him pitch for a little while," Valentine said.
On Thursday, Lowe appeared on Boston sports radio station 98.5 and admitted that the Red Sox were at the top of his list.
With starter Josh Beckett questionable to make his next start Sunday (back spasms) and Aaron Cook struggling of late, Lowe could make some sense for the Sox.
