The Athletics have decided to push the regular-season debut of pitcher Jesse Chavez back to Thursday in the wake of Tuesday's rainout, MLB.com reports.

Chavez was originally scheduled to pitch Wednesday, but it appears Oakland will go with Tuesday's scheduled start Scott Kazmir and a minor-league pitcher in Wednesday's doubleheader. Pushing Chavez back a day means he'll face the Mariners at home on Thursday, while the rest of the team's rotation will also move back a day to accommodate the rainout.
