The Dodgers woke up Wednesday leading the San Francisco Giants by four and a half games in the National League West.

The Giants haven’t played today. Neither have the Dodgers.

Yet the Dodgers now lead the Giants by four games.

That’s because Major League Baseball upheld the Giants’ protest of their 2-0, five-inning loss to the Cubs last night. Here’s the release from MLB:

Major League Baseball announced today that Executive Vice President for Baseball Operations Joe Torre has upheld a protest filed by the San Francisco Giants regarding the calling of their rain-shortened game against the Chicago Cubs at Wrigley Field on Tuesday night.

An examination of the circumstances of last night’s game has led to the determination that there was sufficient cause to believe that there was a “malfunction of a mechanical field device under control of the home club” within the meaning of Official Baseball Rule 4.12(a)(3). Available video of the incident, and conversations with representatives of the Cubs, demonstrate that the Cubs’ inability to deploy the tarp appropriately was caused by the failure to properly wrap and spool the tarp after its last use. As a result, the groundskeeping crew was unable to properly deploy the tarp after the rain worsened. In accordance with Rule 4.12(a)(3), the game should be considered a suspended game that must be completed at a future date.

In addition, Major League Baseball has spoken with last night’s crew chief, Hunter Wendelstedt, and has concluded that the grounds crew worked diligently in its attempt to comply with his direction and cover the field. Thus, there is no basis for the game to be forfeited by the Cubs pursuant to Rule 4.16.
