According to the Baseball America's minor league transactions wire, the Red Sox have signed RHP Doug Mathis.
The 28-year-old comes via Korea, where he finished last season. He had 45 games of experience with the Rangers from 2008-10. Mathis had a 4.84 ERA and a 1.62 WHIP and was mainly used in relief.
He made 17 starts in the minors for the Giants and Athletics last season, going 0-5, 4.27. Released by Oakland in July, he caught on with the Samsung Lions in Korea and pitched well, going 5-2, 2.52 for the eventual league champions.
If spring training goes well for him, Mathis would project to be in the rotation for Class AAA Pawtucket to start next season.
