The A's signed Boof Bonser to a minor league deal, according to Ken Rosenthal of FOX Sports, who notes that Bonser will go to the minor leagues and start (Twitter links). The 28-year-old elected free agency last week after the Red Sox designated him for assignment. A groin injury has limited Bonser to two appearances so far this year; he allowed six hits and walked a pair in his two innings of work.
Bonser, a former first rounder, has not proven himself since missing the 2009 season with shoulder surgery. To his credit, the right-hander posted standout strikeout (7.3 K/9) and walk (2.9 BB/9) ratios in his three-year stint with the Twins.
