OAKLAND -- Three spurts of heavy rain in Oakland Saturday morning lasted into early afternoon, delaying the start of the A's-Twins game.

The game, scheduled for a 1:05 p.m. start, is now set to get underway at 3 p.m.

At the same time, there was another embarrassing sewage leakage. This one, located in the restroom adjacent to the A's coaches office, didn't have any impact on the game's start, but it was a serious sources of Twitter finger-pointing in lieu of the game having not started.

The rain left heavy puddles on the warning track around the field, thoroughly saturated the grass where it wasn't protected by the tarp, and both dugouts dealt with flooding issues.

The A's were saying one inch of rain fell in the Coliseum in the space of one hour, an unusually heavy total for the facility.

The rain took a hiatus about 1:15 p.m., at which time the umpiring crew, managers Bob Melvin of the A's and Ron Gardenhire of the Twins toured the field. But by 1:45 the rain was falling again and the club said there would be an update at about 2:15 p.m.

But outfield playing conditions were questionable enough that Melvin decided to scratch center fielder Coco Crisp and alter his lineup.

The deluge in the coaches' locker area was just the latest in a series of sewage problems hitting the Coliseum this season.

``It was like a sewage volcano,'' A's reliever Ryan Cook said as the A's took the sewage issue in typical good humor.

David Rinetti, the A's vice president of stadium operations and A's clubhouse manager Steve Vucinich both said this sewage leak appeared to be the result of the heavy rain. Sewage leaks in late June and earlier this month were traced back to articles of clothing jammed into toilets.

A's manager Bob Melvin's team entered the day with a magic number of two for sewing up the American League West title, meaning an A's win Saturday and a loss by the Rangers in Kansas City would give the A's the title and move them into the playoffs.
