Tsutsugo opted out of his minor-league contract with the Rangers and became a free agent Thursday, Evan Grant of The Dallas Morning News reports.
Tsutsugo signed a minor-league deal with Texas in the offseason and failed to make the Opening Day roster out of spring training. The 31-year-old infielder is slashing .249/.380/.432 in Triple-A this season and has historically been successful in the minors, so he figures to have no problem securing at least a minor-league deal from another club.
