Zack Greinke was scratched with a sore right calf muscle, so Carlos Frias started Wednesday instead and halted the Dodgers’ four-game losing streak with help from Chase Utley.

The San Diego Padres beat the San Francisco Giants 5-4 in extra innings, so the Dodgers lead the second-place Giants by seven games with 11 to play.

The Dodgers’ magic number to clinch the division is 5. The earliest they can clinch outright is Saturday. Because the Giants’ game against the Oakland A’s begins at 1 p.m. PT, and the Dodgers’ game against the Rockies begins at 5 p.m., it’s possible the Dodgers can clinch the division before they set foot on the field.
