Santa Cruz native Bill Miller, 57, and Dan Iassogna, 55, will serve as League Championship Series crew chiefs.

Miller, a Harbor High and UCLA alum who splits time between residences in La Selva Beach and his cabin in Incline Village, will head the NL matchup between the Los Angeles Dodgers and New York Mets.

Miller will be working his ninth LCS and Iassogna his eighth.

Iassogna will be an LCS crew chief for the second straight year. He’ll work the AL matchup between the New York Yankees and Cleveland Guardians.

Six umpires — Mike Estabrook, Nic Lentz, Gabe Morales, Jeremie Rehak, Chris Segal and Jansen Visconti — will make their on-field LCS debuts this year.

Seven-man crews will work each series, with one umpire off each game.

The NL series starts Sunday with Rehak behind the plate, Marvin Hudson at first, Lentz at second, Miller at third, David Rackley in left, Jordan Baker in right and Mike Muchlinski as the reserve umpire.

Muchlinski will work the plate in Game 2, followed by Hudson, Lentz, Miller, Rackley and Baker.

Hudson will be the NL chief in Game 4, when Miller is the reserve.

The AL series opens Monday with Estabrook behind the plate, Iassogna at first, Segal at second, Alan Porter at third, Vicsonti in left, Vic Carapazza in right and Morales as the reserve umpire.

Morales will work the plate in Game 2, followed by Iassogna, Segal, Porter, Visconti and Carapazza in Game 7.

Porter will be the AL crew chief in Game 2, when Iassogna is the reserve ump.

Hudson, Muchlinski and Porter are working their fourth LCS, and Baker and Carapazza their third and Rackley his second.

Scott Barry, Alfonso Márquez and Ben May will be the replay umpires at Major League Baseball’s office in New York.
