Eddie Bonine elected free agency and Jay Sborz, Max St. Pierre and Jeff Frazier will follow him to the open market this Saturday, according to the Tigers (on Twitter). Detroit outrighted the four players to Triple-A to create roster space.
Bonine pitched to a 4.63 ERA in 68 innings for the Tigers this year. The 29-year-old right-hander struck out 3.4 batters per nine and walked 2.9 per nine in his third big league season.
Sborz, 25, appeared in one game for the Tigers this year, but has spent most of his pro career in the minors. The right-hander has a 4.31 ERA and more than one strikeout per frame in 296 2/3 minor league innings pitched.
St. Pierre, a 14-year minor league veteran from Quebec, finally made his big league debut this year. He didn't do much in nine big league plate appearances, but the 30-year-old catcher did post a .274/.353/.479 line in the upper minors this year.
Frazier, 28, also made his big league debut in 2010. The 2004 third rounder batted .256/.306/.493 at Triple A with 25 homers while playing first base and both corner outfield positions.
