The A's signed lefty Lenny DiNardo to a minor league deal with an invitation to Spring Training, according to Susan Slusser of the San Francisco Chronicle. DiNardo, a "popular guy" in the clubhouse, returns to the A's after spending last year in Kansas City.
The 30-year-old pitched for the A's in 2007-08 and had his most successful major league stint in Oakland. He managed a 4.61 ERA in 154.1 innings over the course of his two seasons by the Bay. The A's will be able to retain DiNardo as an arbitration-eligible player after next season if they so choose, since he won't have enough service time to file for free agency.
