ATLANTA -- The first time Brett Baty stepped on the field in the big leagues, he simply took a look around.
"I wanted to soak it all in," he said.
Then came a moment he'll remember for a lifetime.
After being outscored 18-1 in the first two games of the series, the NL East-leading Mets jumped to a 6-1 lead and barely made it stand up to push their advantage over the Braves back to 4½ games.
And Baty was partially to thank.
The 12th overall pick in the 2019 draft, he came up for the first time in the second inning with a runner aboard and the Mets already ahead 2-0 on back-to-back homers in the first off Jake Odorizzi. After taking a ball, Baty connected with a hanging curve on his very first swing in a New York uniform.
"I was just looking for a pitch I could drive,'' Baty said. "He left one over the plate.''
According to ESPN Stats & Information research, Baty is the fifth player with a home run in his first career plate appearance in Mets history and first since Mike Jacobs in 2005.
Baty, who is from Round Rock, Texas, said pregame that his mother, father, sister and several other relatives had flown to Atlanta for his big league debut. They erupted with applause in their seats upon seeing the ball fly out of Truist Park.
"To look up (in the stands) and see my family up there, to celebrate in the dugout with my teammates, it's just pure joy,'' Baty said.
A worker was able to retrieve the ball, which will become a treasured keepsake for Baty, the 37th-best prospect in baseball by ESPN's Kiley McDaniel, who was called up to the big leagues just a week after being promoted to Triple-A Syracuse.
"For sure, that will be framed up and go on a shelf somewhere,'' he said. "Hopefully there will be more."
Baty's big night came on the same day the Mets placed Eduardo Escobar on the injured list with a left oblique injury.
In other injury developments, pitcher Taijuan Walker underwent an MRI after lasting only two innings in his start Tuesday because of back spasms. Walker may not be able to make his next scheduled start Sunday at Philadelphia, but it doesn't appear he'll be out for an extended period, according to manager Buck Showalter.
"Pretty good news, all things considered," Showalter said of Walker. "His Sunday start is in jeopardy, but we're still holding out hope it manages before that. We've got some different thoughts" about who might step in if Walker can't go.
The Mets designated reliever R.J. Alvarez for assignment after he gave up three runs in 2 1/3 innings in a 5-0 loss to the Braves on Tuesday -- his first appearance in the big leagues since 2015. Lefty Sam Clay was called up from Syracuse.
