LOS ANGELES — The fastballs aren’t all that’s hitting triple digits at the World Series.

This Fall Classic is going to feel like summer.

The Los Angeles Dodgers and Houston Astros will meet on what’s expected to be a 100-degree Tuesday at Dodger Stadium, beginning possibly the warmest World Series ever.

A heat wave slugged Southern California on Monday, with the temperature reaching 104 degrees shortly after lunchtime in Chavez Ravine. It was still blazing when the Dodgers and Astros showed up at Dodger Stadium for brief late-afternoon workouts.

“Never would I have expected that at the end of October, going into November,” Dodgers center fielder Chris Taylor said. “That’s L.A. for you, though.”

Game 1 has a chance to be the warmest World Series game on record. The temperature was around 94 degrees in Phoenix for the opener of the 2001 World Series between the Arizona Diamondbacks and the New York Yankees but they played indoors. Some forecasts expect Los Angeles to be hotter at 8 p.m. on Tuesday.

The Dodgers are in the World Series for the first time since 1988, and the temperature feels normal to the boys in blue.

“Everything is hot in LA!” Dodgers closer Kenley Jansen said with a grin. “The Dodgers are hot. Everybody is excited. It’s been a while since Kirk Gibson. Of course it’s hot today.”

The Astros are also used to a little bit of heat – and in East Texas, they’ve got humidity that can wear out most Californians.

“Hydration is going to be key, and trying to cool off is going to be key,” Dodgers outfielder Curtis Granderson said. “But I think if you would poll everybody, everybody would definitely like it to be a little bit warmer than they would be cold.”

METS: Former Indians pitching coach Mickey Callaway was introduced as the 21st manager in franchise history.

Despite expecting to go into a second round of interviews, Callaway impressed Mets brass immediately, to the point that they scrapped the idea of more interviews.

The 42-year-old, a native of Tennessee who played college baseball for Ole Miss, will become one of the youngest managers in the game, which is in direct contrast to Terry Collins, who was the oldest in the league a season ago.

ANGELS: Eric Hinske is the new hitting coach. Hinske spent the past four seasons on the Chicago Cubs’ coaching staff, including three straight years as the assistant hitting coach on three playoff teams.

Hinske played 12 big-league seasons with seven franchises after winning the AL Rookie of the Year award with Toronto in 2002. A first baseman and outfielder, he won World Series titles with the Red Sox in 2007 and with the Yankees in 2009.

BRAVES: Atlanta declined its $8 million option on 42-year-old knuckleballer R.A. Dickey for 2018 and exercised their option on catcher Tyler Flowers.

Dickey was the Braves’ most consistent starter this season, going 10-10 with a 4.26 ERA in 31 starts. He said at the end of the season he would meet with his family before deciding if he would pitch in 2018.
