Zack Greinke returned to form on Thursday night, and the legend of Yasiel Puig grew.

Greinke fired seven scoreless innings and Puig hit his first Major League grand slam to lead the Dodgers past the Braves, 5-0, at Dodger Stadium in the opener of a four-game series.

Puig, hitless on Wednesday for the first time in his young career, singled in his first at-bat and lined a grand slam to right in the eighth on the first pitch he saw from right-hander Cory Gearrin.

As Puig stepped to the plate, manager Don Mattingly and first baseman Adrian Gonzalez turned to each other in the dugout and joked that Puig would go deep.

"We were kidding, but it doesn't really surprise you," Mattingly said.

Gonzalez and Mattingly weren't the only ones in the Dodgers' dugout who shared that feeling.

"We were all thinking the same thing, we just didn't think it would happen on the first pitch," catcher Tim Federowicz said. "He's a special player."

It was the third multi-hit performance in four games for Puig, who finished 2-for-4 to raise his average to .438. The outfielder has three homers and nine RBIs since making his big league debut on Monday, getting his fourth curtain call in the process and an ice bath from Luis Cruz after the game.

Playing with a renewed energy, the Dodgers improved to 3-1 since Puig's promotion from Double-A.

"I'm very happy that the fans are saying my name and the good thing is the team is winning right now," Puig said through a translator.

In just four games, Puig has proven his worth to the Dodgers and his teammates. He had two hits in his debut, capping a 2-1 win over the Padres with a bullet from right field to first base to double off Chris Denorfia. On Tuesday, Puig homered twice and drove in five runs to lead the Dodgers to a 9-7 victory.

"I feel like he feels he belongs here and he's just proving it right now," said Greinke, who saw Mike Trout bring a similar energy to the Angels last season. "I don't think in his mind he's worried about the pitcher being better than him. He feels he belongs."

Puig's latest heroics even drew a reaction from Matt Kemp, who is rehabbing a right hamstring strain in Arizona.

After the grand slam, Kemp tweeted: "That boy is a beast!!!! #puig"

For Greinke, it was the strongest he has looked in five starts since returning from a broken left collarbone three weeks ago.

"It was definitely big for me," said Greinke, who struck out seven and allowed just four hits. "I've been struggling. But I felt like I've been kind of close. It's still not exactly where I want to be, but it was definitely a fun start."

Just as important, the right-hander's deepest outing of the year helped ease the burden on a bullpen that had worked 11 2/3 innings combined over the last three games.
