Six umpires who finished the MLB season in the western U.S. will work the one-game wild card playoff game today between San Diego and Colorado at Denver.

MLB Vice President of Umpiring Mike Port explained that regional “tie-breaker” crews were on stand-by based on the city they were working in for the last series of the season. Three crews were so designated, one in the west, one central, and one in the east.

Port said that the decision for regional stand-by crews was necessary since so many clubs were still in the playoff hunt as the last weekend of play began.

Tim Tschida and Jim Wolf finished the season working the bases in Colorado and will remain to work the playoff. Tschida will work second base and Wolf right field. Both are assigned to Division Series.

Tim McClelland, who is not assigned to a Division Series, will work the plate Monday night. He finished the season Sunday at Oakland working third base. His season crewmate Fieldin Culbreth, who worked the plate at Oakland, will be in left field at Colorado. He is assigned to the same Division Series crew as Wolf.

Ed Montague, one of four crew chiefs in the Division Series, will work first base. He was at second base in Seattle on Sunday.

Chuck Meriwether, who worked second base Sunday at Dodger Stadium, will be at third base in Colorado. Meriwether is also working the Divisionals.
