ATLANTA - After watching Luis Severino shut down the Indians over six innings on Aug. 22, Brett Gardner smiled in discussing the 21-year-old who had just earned his first big-league win. "First of many, I think," Gardner said.

Victory No. 2 came his next time out. The rookie righthander shut out the Braves over six brilliant innings in a 3-1 victory Saturday night in front of a sellout crowd of 49,243 at Turner Field.

Severino (2-2, 2.17) allowed four hits, walked three and struck out five.

The victory allowed the Yankees (71-57) to remain 1½ games behind the still-scorching Blue Jays in the AL East.

The Yankees, who scored nine runs in the first two innings in Friday night's 15-4 victory, grinded through the night offensively this time.

They had only six hits and took a 1-0 lead into the seventh inning before Didi Gregorius -- who had four hits and a career-best six RBIs Friday night -- doubled home Chase Headley, who also had doubled, to make it 2-0.

Justin Wilson allowed a run in the bottom of the seventh, but Dellin Betances -- after walking a batter to put runners on first and second -- made a nifty behind-the-back stop of Freddie Freeman's comebacker to end the inning.

After Brian McCann's RBI double in the top of the eighth made it 3-1, the Braves put runners on first and third with two outs in the bottom of the inning, but Betances struck out Andrelton Simmons looking.

Andrew Miller struck out two in a perfect ninth for his 28th save.

As they did Friday night, the Yankees scored early, though not as often.

Leadoff man Jacoby Ellsbury flared the third pitch he saw from Braves righthander Matt Wisler (5-5) -- who allowed two runs, four hits and four walks in six innings -- for a double to left. Gardner's grounder to second moved Ellsbury to third and Carlos Beltran struck out, but McCann and Greg Bird walked to load the bases. On an 0-and-2 pitch to Headley, Wisler planted his next delivery in the dirt for a wild pitch that made it 1-0. Wisler ended the 30-pitch inning by striking out Headley.

Nick Markakis led off the Braves' first with a single and Freeman worked a one-out walk, but Nick Swisher grounded into a 4-6-3 double play to end the 15-pitch inning.

The Braves did not get another runner in scoring position until the fourth, when Adonis Garcia missed tying the score by only a few feet, driving a two-out double off the wall in center for the Braves' second hit. Severino walked Jace Peterson but struck out Christian Bethancourt with a 96-mph fastball.

Severino experienced no such trouble in the fifth, needing only 12 pitches to set down the Braves in order, two on strikeouts. He got Simmons swinging at a 97-mph fastball to start the inning and Markakis looking at a 97-mph fastball to end it.

The Braves doubled their hit total in the sixth, getting two-out singles by Swisher and Garcia, but Peterson bounced Severino's first pitch to second for the third out, leaving the righthander at 88 pitches through six.
