NEW YORK -- Filmmaker Ken Burns is wading into baseball's steroids era for a postscript to his 1994 PBS documentary about the sport.
The nine-part 1994 series "Baseball" was a refuge for fans during a year the sport was shut down for a strike.
PBS says Burns is following it up with "The Tenth Inning," a four-hour documentary that will air Sept. 28 and 29, just before playoffs begin.
The film essentially covers Major League Baseball since 1994. Covered are the rise in performance-enhancing drugs, the sport's international flavor because of Asian and Latino players, a new Yankees dynasty and the breakthrough of the Boston Red Sox.
A DVD and Blu-ray disc will be available a week later with two additional hours of material.
