Red Sox's Naoyuki Uwasawa: Departs 40-man roster

The Red Sox designated Uwasawa for assignment Tuesday, Mac Cerullo of the Boston Herald reports.

Uwasawa will yield his spot on the 40-man roster to Trey Wingenter, who was acquired Saturday via trade and is getting called up by Boston. Uwasawa registered a 6.54 ERA in 42.2 innings at Triple-A Worcester this season. Assuming he clears waivers, the 30-year-old should remain in the Red Sox organization.
