The White Sox released Alan Embree, who had been pitching at Triple A, according to Mark Gonzales of the Chicago Tribune (via Twitter). The White Sox signed Embree earlier in the month, after the lefty elected free agency. He pitched in the majors and the minors for the Red Sox this year before his stint in the White Sox organization.
The 40-year-old struggled at Triple A Charlotte, allowing 11 hits and five walks in 7.1 innings, though he did strike ten batters out. If any teams have interest in Embree, it would presumably be on a minor league deal. The D'Backs have no left-handed pitchers on their staff and their bullpen has combined for a 7.42 ERA.
