Feliz, 35, was signed as infield insurance but had an out in his contract that he could secure his release if he was not placed on the Major League roster.
He was used little during Spring Training as Mike Aviles solidified his job as the regular third baseman and Wilson Betemit emerged as a probable infield backup.
Feliz played in 15 Cactus League games and batted .167 (4-for-24) with two doubles, a home run and three RBIs.
Known as an outstanding glove man, Feliz played nine years for the San Francisco Giants and hit 20 or more homers in four straight seasons, 2004-07. After two years with the Philadelphia Phillies, he split last season between the Houston Astros and St. Louis Cardinals.
