The New York Mets beat the Boston Red Sox, 8-3, in the final game of their two-game two-step between Beantown and Flushing this week, making it two in a row for the Metsies. Let’s delve into the happy recap…

Left-hander David Peterson, making his MLB debut after being selected 20th overall by the Mets in the 2017 draft, contributed a solid 5.2 innings, giving up two runs on seven hits with three strikeouts and two walks.

The Mets’ bullpen looked strong, allowing two hits and a run over 3.1 innings with no walks — including another gem of an outing from left-hander Justin Wilson — and the Metsies’ offense led the way in New York’s second consecutive win in Beantown.

J.D. Davis went 2-for-3 with a two-run homer, Jeff McNeil went 2-for-5 with two RBIs, and Robinson Cano went 2-for-3 with a run driven in, hoping to shake out of his early-season funk.

Pitching

Peterson began his major league career by serving up a hard-hit single to Jose Peraza that hammered the Green Monster in left field, but J.D. Davis made a terrific play on the carom and an even better throw to nab him at second.

The Denver, Colorado product struck out J.D. Martinez looking at an 83 MPH slider in his second MLB plate appearance and finished off a clean first inning with a 6-4 putout via Rafael Devers.

The 24-year-old southpaw worked around a Kevin Pillar infield single in a scoreless second but found himself in trouble in the third.

A Kevin Plawecki leadoff double, walk to Andrew Benintendi, and a long base hit via Peraza that Brandon Nimmo nearly nabbed in centerfield loaded the bases with none out. Welcome to the show, David.

Peterson struck out Martinez swinging (slider), induced a line drive out from Devers, and the Mets caught Benintendi dancing off second amid the confusion (second base umpire ruled Devers’ liner a non-catch) to escape with a lone run scored (crossed during ensuing rundown). Get all that?

After a perfect fourth, Peterson headed into the fifth at just 52 pitches. Economic stuff. After setting down Jackie Bradley Jr.swinging at a crisp slider, Plawecki reached on an infield hit and Benintendi walked, but Peterson drew Peraza into a 4-6-3 inning-ending double play.

Devers struck back in the sixth with a one-out double in centerfield and Pillar added an RBI double of his own to make it a 5-2 game, ending Peterson’s night after 5.2 innings (78 pitches; 46 strikes).

Right-hander Drew Smith entered to face fellow righty Michael Chavis, who was then pinch-hit for by left-hander Mitch Moreland, who proceeded to strike out swinging at a 96 MPH four-seamer, ending the threat.

Justin Wilson got the call in the seventh and turned in a perfect frame, his third consecutive scoreless appearance to start the season. Dellin Betances breezed through the eighth without much adversity (gave up a Devers two-out base hit), and Hunter Strickland allowed a run in the ninth to secure a big win before heading back home.

Offense

The Mets were set down in order in the first by Red Sox lefty Matt Hall before J.D. Davis got New York started with a leadoff base hit in an eventful second inning.

Yoenis Cespedes was hit by a pitch and Robinson Cano, mired in a 1-for-12 slump to start the season, went the other way with an RBI single to put the Mets ahead, 1-0.

Brandon Nimmo walked to load the bases with two outs, and Amed Rosario blooped a single into shallow right to bring home two more runs, staking New York to a 3-0 lead.

Jeff McNeil singled with one out in the fifth and Davis brought him home with a two-run homer — his first of the year, as well as his first two RBIs — off the Pesky Pole in the right-field corner to make it a 5-1 game.

Robinson Cano added his second hit of the game in the eighth, a double off the Green Monster in left field. He was pinch-ran for by Andres Gimenez, who broke for second on Ramos’ groundball, eliminating the double play; heads up play.

Right on cue, Nimmo brought him home with a first-pitch RBI double to extend the Mets’ lead to 6-2. Following an Alonso bases-on-balls, McNeil notched his second hit of the night — a bases-clearing double off the wall in left-center — to make it an 8-2 game.
