Morton suffered a fracture of his lower right leg after he was struck with a batted ball in the second inning of Tuesday’s game, which Atlanta won, 6-2. He is out for the rest of the series and went to Green Bay, Wis., to see a specialist for the injury. Davidson, a left-handed pitcher from Amarillo, Texas, said as soon as he saw Morton leave the game, he had a gut feeling that he would get the call. He was right.

Within a few hours, he was told to get a plane for Houston early Wednesday morning and was at Minute Maid Park in time for batting practice before Game 2.

“It’s a huge deal,” he said. “It’s an honor to be here. Pitching in Texas is going to be awesome. I haven’t done that, I don’t think, since college. That will be a fun, unique experience. The opportunity to make my postseason debut in the World Series.”

Brian Snitker, Atlanta’s manager, would not detail how Davidson would be used, but suggested he could be available out of the bullpen.

Davidson made four starts for Atlanta this season before he was shut down with left forearm soreness. When he recovered in October, he was assigned to Atlanta’s alternate site and worked out to prepare for this opportunity.

“Reports were really good how he was throwing,” Snitker said, “and he feels good. He did a really nice job for us when he was here the first time.”

“Everybody gets doubt once in a while,” Jackson said. “No matter how good you are, no matter how well you’re playing, it’s always nice to hear something positive from someone that’s been down the road you’d like to go. I played with great players and had a lot of support, so when a player struggles a little bit, it’s a big help when he can look through experienced eyes and a guy says to him, ‘Don’t worry about it, you’re going to be all right.’”

Even before he joined the Astros, Jackson avidly watched their games. In the press elevator after Game 5 of the 2017 World Series — a tour de force by second baseman Jose Altuve — Crane proudly showed a text message from Jackson.

“Altuve, the best player in the game,” read the message. “Says who? Says Mr. October.”

“There’s always going to be a predominant wind direction, which with the roof open will probably take away some of our home-field advantage,” he said, “because we don’t really probably know much more how the ball’s going to carry in a predominant wind any more than they do.”

Then again, Houston has not won a World Series home game in their last five tries, losing four times to Washington in 2019 and Tuesday’s Game 1 to Atlanta.

But with Game 2 — and possibly Games 6 and 7 — to be played in Houston, it’s entirely possible we will see more unusual plays in the outfield before this series is done.

“I’d say it’s one of the trickiest outfields in the big leagues, just the way it bounces off the surfaces,” said Adam Duvall, who played center and right on Tuesday. With Minute Maid overflowing with strange things to hit — padding, brick, the outfield fence, safety fences, the scoreboard and a roof — Duvall said Atlanta’s outfielders had spent time ahead of the series practicing how to deal with their varied effects.

“We tried to hit on all that and tried to figure out where we need to be when it bounces off the wall,” he said. “That’s preparation. That’s the little things that people may not see at home, but that’s part of prepping. That’s part of what we do. We try to cover all the little things because little things become big things in games like this. That was a big play.”

Every park has its own ground rules. Here are some highlights of Houston’s:

• If a batted ball gets lodged in — or goes through — the out-of-town scoreboard in left, it’s a double. The outcome is the same if a ball strikes the top of the scoreboard and bounces into the stands.

• Staying in left, a batter homers if the ball hits the fence’s yellow line, or the top of the left-center railing “at a point above the stands,” and continues into the seating area. But if the ball bounces into the field, it’s in play.

• In right, a ball is in play when it hits even the slightest part of the yellow line on the outfield wall and comes onto the field.

In 1996, the Braves won Games 1 and 2 over the Yankees and then lost the next four. Atlanta also took Game 1 of the 1992 World Series, but eventually lost the series to Toronto.

But in almost two-thirds of World Series’, the Game 1 winner has ultimately taken home the title. One of the exceptions: Houston, which faltered in Game 1 in 2017 and then won the franchise’s lone — and, many believe, tainted — championship. In fact, Tuesday’s loss moved the Astros franchise to 0-4 in World Series openers across 2005, 2017, 2019 and this year.

“We’ve moved past it,” Framber Valdez, the losing pitcher in Game 1, said afterward. “Tonight’s over. Tomorrow we’re going to come in here and try to win it and do everything we can to get our first win in the World Series.”

And Dusty Baker, Houston’s manager, said his team “doesn’t worry, and our team’s very confident.”

“We have the knack of bouncing back after losses, after tough losses because they don’t quit, they don’t give up, they don’t get down,” he added. “That’s the secret of sports.”

Baker would know: When he played for Los Angeles, the Dodgers lost the first and second games of the 1981 World Series. Then they pulled off four straight victories over the Yankees to give the franchise its first championship since 1965.

He last pitched a major league game on June 15, when he left a game against Boston and afterward went on the injured list with forearm trouble.

Davidson will be filling the spot of one of baseball’s premier postseason pitchers, especially in winner-take-all games. A comebacker struck Morton in the second inning on Tuesday, but Atlanta has not said when, exactly, he was injured and he threw 16 pitches — and got three outs — after being hit.

The questions around the timeline, though, did not change the outcome that Morton’s season was finished.

“He wants to be on this stage,” Brain Snitker, Atlanta’s manager, said. “God bless him, I hate it for him. Really hate it for him. He’s such a great person, great person and teammate. I do, I really hate it for him because I know he’s really looking forward to this run with us. So we’ll move on.”
