Local duopoly stations KCBS Channel 2 and KCAL Channel 9 announced a major revamp of their news anchor lineups Wednesday, including switching KCAL's main prime-time anchor, Pat Harvey, to the KCBS anchor desk and bumping KCBS anchor Laura Diaz to a solo anchor spot at 6 p.m.

Harvey, the veteran anchor who has been the main face of KCAL since the station launched the country's first three-hour nightly newscast 20 years ago, will co-anchor the 5 p.m. and 11 p.m. news with Paul Magers. Diaz had been Magers' co-anchor in those newscasts since he joined KCBS in 2004.

KCBS weekend anchor Sharon Tay will succeed Harvey on KCAL's 8 and 10 p.m. newscasts.

Jackie Johnson, who handled weather for KCAL, will succeed retiring weather reporter Johnny Mountain on  KCBS' 5, 6  and 11 p.m. news. Mountain last month announced that he was leaving the station after 32 years on local television. Josh Rubenstein will take over Johnson's KCAL weather duties for the time being.
