Right-handed reliever Logan Bawcom could be returning next season to Triple-A Tacoma.
The Mariners sent Bawcom to the Rainiers on an outright assignment Monday after he cleared waivers. He was 4-4 with a 4.93 ERA last season in 40 appearances at Tacoma.
Bawcom, 26, was designated for assignment last Wednesday by the Mariners to clear space on their 40-man roster for outfielder Justin Ruggiano, whom they obtained in a trade with the Chicago Cubs.
The Mariners acquired Bawcom with outfielder Leon Landry from the Los Angeles Dodgers in a July 30, 2012 trade for right-hander Brandon League.
The Dodgers picked Bawcom in the 17th round of the 2010 draft. He is 19-16 with a 3.20 ERA in 212 minor-league games in a five-year professional career.
