Righty Juan Gutierrez has opted out of his minor league contract with the Giants, MLBTR’s Steve Adams reports (Twitter links). The 31-year-old had agreed to that pact over the winter after declining an outright assignment from the club.

Gutierrez played a big role in the San Francisco pen last year, throwing 63 2/3 frames of 3.96 ERA ball. He posted 6.2 K/9 against 2.3 BB/9 in his most productive full season as a big leaguer. All said, Gutierrez has tossed just under 300 innings at the major league level, compiling a 4.49 career ERA.

The results have not quite been there for Gutierrez at Triple-A this year, as he has allowed 13 earned runs in his 23 2/3 innings of work. He has struck out 21 batters against eight walks, however, falling largely in line with his career marks. As Adams notes, Gutierrez still brings a mid-90s heater and has enough big league experience that he ought to draw interest from other teams.
