Brett Anderson has agreed to a minor league deal to rejoin the Oakland Athletics, the San Francisco Chronicle reports.
Anderson was primarily a starter for the A's in his first stint with the team from 2009 to 2013.
The 30-year-old left-hander had a 6.34 ERA and a 4-4 record in 13 starts last year for the Chicago Cubs and Toronto Blue Jays, who acquired him on Aug. 15. He signed a $3.5 million, one-year contract with the Cubs during the 2016 offseason.
Anderson has dealt with several injuries during eight big league seasons and was limited to six starts with Chicago because of a lower-back strain before being designated for assignment on July 26.
