A rare offensive outburst from the Mets provided more than enough run support for Matt Harvey Saturday night.

Harvey allowed two runs and six hits in seven innings, striking out four and walking one in improving his record to 9-7. He also went 2-for-4 with a double and a pair of RBIs.

His only blemishes in the Mets' 15-2 win over the Dodgers were homers by Jimmy Rollins in the fifth and Joc Pederson in the sixth.

"I think the biggest thing was I finally felt like I had my slider," Harvey said. "That makes things completely different."

Harvey threw his slider 23 times Saturday night (22.7 percent of his pitches) after entering the game using the pitch 14.9 percent of the time, according to the pitch tracking site BrooksBaseball.net.

The Mets' 15 runs not only represented more offense than Harvey needed but more run support than he had ever received in his big-league career (his previous high was eight).

"Putting up runs like that, I had to go out and continue to try and put up zeros," Harvey said. "I let two pitches get away. I hung two curveballs, but with the run support, I could have hung a lot more and we would have been fine."

Harvey improved his ERA to 3.16 and WHIP to 1.02. He is averaging 8.4 strikeouts and 2.2 walks per nine innings this season.

He also displayed better control than he had in his previous three starts, in which he averaged 6.2 walks per nine innings. It was an atypical trio of outings for Harvey, who entered Saturday allowing 2.2 walks per nine innings in his career.

Said Harvey: "Tonight, I think the big thing was what [pitching coach Dan Warthen] picked up on video this past week. He said 'his leg kick was getting too high . . . and that was causing a lot of issues.' We just wanted to make it simple, go back to what I had been doing before the surgery. It definitely paid off."

Along with Jacob deGrom and Noah Syndergaard, Harvey has anchored a starting rotation that came into Saturday with a 3.49 ERA, seventh-best in the majors.
