The San Diego Padres, in need of pitching reinforcements as they try to hang on to their wild-card lead, have signed right-hander Jake Arrieta to a minor league contract.
Arrieta, 35, is expected to be added to the major league roster on Wednesday to make a start against the Colorado Rockies in Denver.
Arrieta was released by the Chicago Cubs last week after he was 5-11 with a 6.88 ERA this season in his second stint with the franchise.
The Padres placed Yu Darvish on the 10-day injured list Sunday with lower back tightness.
