The question was how Jacob deGrom would respond to facing the Braves for the second time in a week.

Perhaps it should have been the other way around.

The rookie righthander shut out the Braves for seven innings on Tuesday night, lifting the Mets to an 8-3 win at Citi Field for the 4,000th victory in team history and just the second in the major leagues for the young pitcher.

The Mets (41-49), who stand at 4,000-4,374 since starting play in 1962, have won three straight games and four of the first five of this 10-game home stand heading into the All-Star break.

The Braves (49-41) have lost three straight after a season-long nine-game winning streak.

DeGrom (2-5) gave up seven hits, didn’t walk a batter and struck out 11. He also benefitted from a big night of Mets offense.

Curtis Granderson homered leading off the game for the third time this season and 27th of his career, and the rout was on.

Every Met in the starting lineup had a hit, and the first seven had at least two in the 18-hit attack, a Citi Field high for the Mets.

Even deGrom, batting in the eight hole, had a single and scored as the Mets plated three in the second to take a 4-0 lead. Julio Teheran (8-6), who held the Mets to a single run in seven innings last week, couldn’t get out of the fourth inning on Tuesday, allowing five runs on 11 hits and two walks.

While the run support was nice — and very rare in his short major league career — deGrom (2-5) didn’t need much of it.

“I wanted to go out and get the win,” deGrom said, citing his loss to Teheran and the Braves seven days ago. In that game deGrom gave up three runs in the first inning, and although that was all he allowed in five innings, he was pinned with the defeat. “I wanted to put up zeros tonight.”

DeGrom struck out 11 for the second time, joining Nolan Ryan and Dwight Gooden as the only pitchers in team history to achieve that feat in their first 11 starts. While he had already experienced facing a team twice this season — he started against the Pirates May 26 and June 27 — Tuesday night was the first time that he had to face the same lineup in back-to-back outings.

It is a challenge for a young pitcher to recognize when and how hitters are beginning to adjust to him, former Mets pitcher and SNY analyst Ron Darling said Monday.

“Recognizing that is going to happen, you don’t know when it is going to happen. Sometimes they won’t make adjustments,” Darling said. “I think it’s important for him to learn. He’s got to go into the game with a certain game plan, but learn to have the ability to chuck it if you have to.”

DeGrom certainly impressed his manager.

“He’s had some good ones,” Terry Collins said. “Like I said before the game, he’s had some ups and downs, but he’s a young guy. He’s getting better.

“People were asking about him facing the same team back to back. Well, all he did was make great pitches tonight.”
