California (CIF) baseball: Section-by-section start/end playoff dates, defending champions

Like a fastball from Paul Skenes — a California prep product by the way (El Toro High School) — the high school baseball season in California is rocketing by.
The state's 10 sections open their playoffs in the next few weeks — all with different starting dates — followed by the California Interscholastic Federation regional playoffs (North and South) June 3-7.
The state has yet to agree on a state championship format which would pit the North champions versus the South, though one is anticipated in the next few years.
