Cubs signed RHP James McDonald to a minor league contract with an invitation to spring training. McDonald made just six starts for the Pirates last season, posting a 5.76 ERA while also battling shoulder issues. He flashed plenty of upside for them from 2011-12, though, posting a 4.21 ERA while striking out 293 over 342 frames. McDonald should get a shot to compete for a rotation spot with the Cubs but could wind up in the bullpen. It's a solid no-risk move for Chicago.
