– A mega-ridge of high pressure is baking the Southwest in record heat. The climax of this unbearable weather will arrive Tuesday — just in time for Game 1 of the World Series, which will boast triple-digit temperatures.

After a 101-degree high temperature around 3 or 4 p.m. local time Tuesday, the forecast for first pitch at Dodger Stadium about an hour later is approximately 96 degrees, under crystal-clear skies and a baking Southern California sun. Humidity will be all but nonexistent, which means players (and fans) will be at higher risk for dehydration.

A high temperature above 99 degrees that afternoon would be an Oct. 24 record for downtown Los Angeles. The standing record for the date is 99 degrees set in 1909.

More notably, Game 1 will in all likelihood set an MLB record, too — for hottest World Series temperature.

In 2001, the Diamondbacks hosted the Yankees in Phoenix for Game 1 in what is the hottest Fall Classic game on the books. The first-pitch temperature for that game was 94 degrees. That's the hottest game on record, according to meteorologist Alex Lamers, who has a special interest in baseball weather.

The World Series has fallen victim to extreme weather in the past, but the most severe temperatures have come in the past two decades, according to Lamers' stats. On the other end of the spectrum, the coldest Series game on record was in 1997, when the Cleveland Indians played host to the Florida Marlins on Oct. 22. The temperature at first pitch was 35 degrees. And it was snowing.

Seager likely to play

Dodgers manager Dave Roberts said All-Star shortstop Corey Seager is taking aggressive ground balls during the team's workout in preparation for Game 1.

Roberts said that unless something "really unforeseen happens," he expects Seager to be on the World Series roster, which is due several hours ahead of first pitch.

The 23-year-old Seager hurt his back on a slide in Game 3 of the NL Division Series at Arizona and was left off the NL Championship Series roster while he recovered.

Seager said he hasn't tried to slide since, but only because he hasn't thought about it. He participated in the Dodgers' workout Monday.

Longtime rivals

Roberts and Astros manager A.J. Hinch go back to their days on rival Pac-12 baseball teams. Hinch played at Stanford and Roberts was at UCLA.

Hinch joked the two men are "mortal enemies" during the World Series, in which each is making their managerial debuts. They became close in San Diego, where Hinch was assistant general manager for the Padres and Roberts was a coach.

Back in July, Hinch said he and Roberts shared breakfast and talked about facing off in the World Series. Hinch added that he is proud and happy that their discussion became reality.

Etc.

• Gerry Davis will work the World Series for the sixth time, tying Joe West for the most times among active umpires. Davis will be crew chief for the third time. Phil Cuzzi will be behind the plate for Game 1. Paul Nauert will be at first, Davis at second, Laz Diaz at third, Bill Miller in left and Dan Iassogna in right.

• Astros outfielder Jake Marisnick won't be on Houston's World Series roster. He broke his right thumb midway through last month, cutting short a season in which the 26-year-old hit 16 home runs in 106 games.
