The Red Sox have acquired righthanded pitcher Robert Manuel off waivers from the Seattle Mariners.

Manuel, 26, played his first Major League game this season with the Cincinnati Reds. He pitched 4 1/3 innings over three games, all relief appearances. He began the season with Cincinnati’s Triple-A team in Louisville and was 3-4 with 10 saves and a 2.70 ERA in 46 2/3 innings. He made 36 relief appearances.

Manuel was traded to Seattle on July 29 in exchange for outfielder Wladimir Balentien and finished the season with Triple-A Tacoma, going 1-1 with four saves and a 3.32 ERA in 15 appearances.

He was originally signed by the New York Mets as a non-drafted free agent in 2005.
