CHICAGO -

The San Francisco Giants will get another shot at the Chicago Cubs after Major League Baseball reversed the umpires' decision to end Tuesday's game after 4 1/2 innings due to unplayable field conditions at Wrigley Field.

Baseball officials on Wednesday agreed with the Giants' protest and called for the game to be resumed Thursday at 4:05 p.m. CT.

The Cubs confirmed the game would pick up with the hosts coming to bat in bottom of the fifth inning with a 2-0 lead.

The regularly scheduled series finale will follow at approximately 7:05 p.m.

It was the first MLB protest upheld since June 18, 1986, when the Pittsburgh Pirates got similar ruling after a rain-shortened loss to the St. Louis Cardinals. That game also was ordered to be resumed.

A surprise 15-minute rainstorm hit in the fifth inning Tuesday, and Wrigley Field's grounds crews had trouble positioning the tarp on the infield, leading to excessive water on the field and difficulty restoring it to playing condition.

Play was halted for 4 hour, 34 minutes until umpires finally called the game at 1:16 a.m., giving the Cubs what turned out to be a temporary 2-0 victory.

MLB executive vice president Joe Torre ruled that Tuesday's game should be resumed because of a "malfunction of a mechanical field device under control of the home club."

According to a press release from MLB, "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."

Giants manager Bruce Bochy said, "I thought we had a strong case. We felt very strongly about it. I'm just thankful and grateful they were open-minded. They listened and they looked at it, and I think it's a fair thing to do.

"I don't know what's going to happen. We may not win it, we may not lose it, but at least we're going to finish the game."

The Cubs said ticket holders from the Tuesday game could redeem tickets for the resumed game Thursday and remain for the evening contest.

The game is crucial to the Giants' playoff hopes. By beating Chicago 8-3 Wednesday, the Giants opened a 1 1/2-game lead over the Atlanta Braves for the National League's second wild-card spot.
