LOS ANGELES — Eighteen innings in Game 3 of the World Series at Dodger Stadium again.And this Hollywood rerun had a similar ending.Freddie Freeman homered leading off the bottom of the 18th, Shohei Ohtani went deep twice during another record-setting performance and the Los Angeles Dodgers outlasted the Toronto Blue Jays 6-5 in an instant classic Monday night.The defending champion Dodgers took a 2-1 lead in the best-of-seven matchup and still have a chance to win the title at home — something they haven’t done since 1963.“That could go down as one of the greatest games of all time,” manager Dave Roberts said.Freeman drove left-hander Brendon Little’s full-count sinker 406 feet to straightaway center field, finally ending a baseball marathon that lasted 6 hours, 39 minutes, and matched the longest by innings in postseason history.“Oh gosh, just pure excitement,” he said. “That’s as good as it gets.”The only other World Series contest to go 18 innings was Game 3 at Dodger Stadium seven years ago.
