BOSTON — The Boston Red Sox earned 108 victories in the regular season, and it turns out they hadn’t even played their best. Now they have, and as the World Series shifts to Dodger Stadium for Game 3 on Friday, a sense of inevitability moves with it.

The Red Sox have beaten the Los Angeles Dodgers twice, convincingly. If you book a return flight to Boston for Games 6 and 7, make sure it is fully refundable. This World Series could easily end before then.

“We knew we were going to have a good team — good lineup, good chemistry, good energy — but not that good,” said third baseman Eduardo Nunez, the only Red Sox hitter with a home run so far. “We can beat you with homers, defense, pitching, base hits, stolen bases. I think we have it all.”

They do, and they have played nearly flawless baseball all month, winning nine of 11 games. So far in the World Series, the Red Sox’ biggest mistake is a bounced first pitch by their grand old man, Carl Yastrzemski, before the opener — and even that turned out fine. The 79-year-old Yaz demanded the ball back from his catcher, the injured Dustin Pedroia, and tossed a strike.
