ST. PETERSBURG, Fla. -- Reliever Naoyuki Uwasawa was traded to the Boston Red Sox from the Tampa Bay Rays for cash.
Boston selected the contract of Uwasawa to the 40-man roster before Thursday's opener at Tampa Bay, then optioned him to Triple-A Worcester.
Uwasawa had a 13.03 ERA in 9 2/3 innings over four spring training appearances, allowing 14 runs and 15 hits that included three home runs. He walked eight and struck out nine.
The 30-year-old right-hander agreed in January to a $25,000 signing bonus as part of a minor league contract.
