Red Sox's Kyle Martin: Dropped from 40-man roster

Martin was designated for assignment by the Red Sox on Tuesday, Evan Drellich of CSN New England reports.

The move clears room on the 40-man roster for Carson Smith, who was activated from the 60-day disabled list in a corresponding move. Martin compiled a 4.36 ERA and 50 strikeouts through 53.2 innings with Triple-A Pawtucket this season. He'll take a spin through waivers to determine his landing spot.
