New York Mets vs Boston Prediction & Odds:
Free MLB Betting Insights for 5/20/25

The May 20, 2025 matchup between the New York Mets and Boston Red Sox at Fenway Park continues an intriguing interleague series that pits one of the National League’s most consistent performers against an American League team trying to stabilize in a tough division. The Mets enter the game with a 29-18 record, leading the NL East behind a potent combination of veteran power, timely hitting, and a pitching staff that has quietly anchored their success. Their offense is led by Pete Alonso, who is hitting .302 with 9 home runs and 31 RBIs, and Juan Soto, who has added 8 homers, 28 RBIs, and an impressive .826 OPS. Together with Francisco Lindor, who provides both power (9 HRs) and speed (6 stolen bases), the Mets have formed a dangerous heart of the order that punishes mistakes and capitalizes on scoring opportunities. On the mound, Clay Holmes (3.14 ERA) is expected to start, a rare transition to the rotation from his previous role as a reliever, where he had success with the Yankees. Holmes’ pitch mix and ability to induce ground balls may play well against a Red Sox team that thrives on hard contact. Defensively, the Mets have been solid, and their bullpen has played a major role in preserving tight wins, often shutting down rallies and closing games with efficiency.

Meanwhile, the Boston Red Sox arrive with a 23-25 record and are still seeking consistency in all phases of the game. Offensively, they have firepower, ranking top 10 in wRC+ and wOBA, largely thanks to the contributions of Rafael Devers and Trevor Story. Devers remains one of the league’s most feared left-handed bats, while Story is enjoying a bounce-back campaign with multi-hit games and consistent run production. The Red Sox are slated to start Walker Buehler, who is continuing his return to form after missing time earlier in the season. Buehler’s command and experience could be crucial against a patient and powerful Mets lineup that doesn’t chase and has multiple hitters capable of changing the game with one swing. Boston’s bullpen, however, has been unreliable—giving up late leads and struggling to execute in tight spots—which has played a major role in their 3-7 record ATS in their last 10 games. Their 13-11 home record at Fenway offers some encouragement, and the quirky dimensions of the park always add an element of unpredictability. For the Red Sox to win, they’ll need early runs, a clean outing from Buehler, and improved bullpen management. The Mets, on the other hand, will look to apply pressure early, work deep counts, and rely on their bullpen to seal things if they have the lead late. This game features stars on both sides, potential for offensive fireworks, and critical implications for momentum as both teams jockey for position in competitive divisions. While the Mets have the edge on paper, Fenway Park has a history of leveling the playing field—and if the Red Sox find rhythm at the plate, this could become a back-and-forth, high-scoring affair worthy of primetime attention.

New York Mets Mets MLB Preview

The New York Mets continue to roll into the heart of the 2025 season with one of the National League’s most balanced rosters and a 29-18 record that reflects their blend of power, discipline, and depth. Sitting atop the NL East, the Mets have excelled thanks to a lineup that consistently applies pressure, a pitching staff that limits damage, and a bullpen that reliably shuts the door. Pete Alonso continues to be the offensive anchor, mashing his way to a .302 batting average with 9 home runs and 31 RBIs, delivering not just power but improved contact and a stronger two-strike approach. Alongside him, Juan Soto has been his usual self—patient, powerful, and productive—contributing an .826 OPS, 8 home runs, and a team-high 28 RBIs, while Francisco Lindor has added another dimension with 9 home runs, 6 steals, and his characteristic defensive prowess up the middle. The top of the Mets lineup sets the tone early, with frequent extra-base hits and one of the lowest strikeout rates in the NL, forcing opposing pitchers into high-stress innings from the jump. Rookie Brett Baty and veteran Jeff McNeil provide depth in the order, capable of flipping the lineup over and extending rallies, giving manager Carlos Mendoza the luxury of quality plate appearances throughout the order. On the mound, Clay Holmes is expected to make a rare start, transitioning from his usual bullpen role where he’s thrived with a 3.14 ERA and a sinker that generates weak contact.

The decision to use Holmes in this spot reflects confidence in his ability to induce ground balls and navigate Boston’s powerful but inconsistent lineup. The Mets’ bullpen remains one of the team’s greatest strengths, with Edwin Díaz anchoring the ninth and setup men like Brooks Raley and Drew Smith excelling in tight, late-game situations. Defensively, New York has been sharp—ranking among the league leaders in team fielding percentage—thanks to solid fundamentals and consistent positioning. Though their 12-13 road record suggests a slight dip in performance away from Citi Field, the Mets have won six of their last eight on the road, including tight series in Philadelphia and Milwaukee, and enter Fenway Park with growing confidence. The game plan against Boston will focus on pitch efficiency early, minimizing middle-of-the-plate mistakes to dangerous hitters like Rafael Devers and capitalizing on the Red Sox bullpen, which has been vulnerable in late innings. Holmes will look to pitch to contact, trust his infield defense, and set up favorable matchups for the bullpen. If the offense continues to grind out at-bats and deliver with runners in scoring position, the Mets are well-positioned to continue their winning ways. With a healthy core, emerging young talent, and a bullpen that shortens games, New York appears poised not only to leave Fenway with a series win but also to solidify their status as one of the NL’s most complete and dangerous clubs heading into the summer months.

Boston Red Sox MLB Preview

The Boston Red Sox enter their May 20 clash with the New York Mets clinging to the hope of finding sustained traction in a turbulent 2025 season, bringing a 23-25 record into Fenway Park and desperately seeking consistency in all facets of their game. While their offense has shown flashes of being among the league’s most potent—ranking top 10 in both weighted runs created plus (wRC+) and weighted on-base average (wOBA)—defensive miscues, bullpen collapses, and starting rotation instability have undermined their efforts to stay competitive in the American League East. At the heart of their offensive production stands Rafael Devers, who remains the most feared bat in the lineup with his ability to launch balls over the Monster and work deep counts. Trevor Story has also begun to find rhythm after a slow start, driving in runs and anchoring the infield with more consistent defensive work. Outfielder Jarren Duran continues to emerge as a valuable spark plug with his blend of speed, contact, and aggressive baserunning, giving manager Alex Cora more options atop the order. But the Red Sox have not capitalized consistently enough on scoring opportunities, often stranding runners and allowing opposing teams to creep back into games they had early control of. On the mound, Boston hands the ball to Walker Buehler, who is still working back to full form following his return from injury.

Buehler’s stuff remains electric, and his postseason experience gives the Red Sox a dependable presence when he’s commanding the zone, but inconsistency with his fastball location and early inning traffic have limited his efficiency. Against a Mets lineup packed with patient, power-heavy hitters like Pete Alonso and Juan Soto, Buehler must avoid falling behind in counts or leaving pitches over the heart of the plate. The biggest concern for Boston remains its bullpen, which has surrendered multiple leads over the past two weeks and posted one of the higher WHIPs in late-inning situations. Relievers have struggled to consistently throw strikes, and the lack of a lockdown closer has forced Cora to mix and match depending on matchups, which hasn’t always worked in their favor. Fenway Park, however, remains one of their few steady advantages. At 13-11 at home, the Red Sox play with noticeably more energy and often generate more offensive flow in front of a passionate and vocal fan base. If the offense can jump on Clay Holmes early—especially given that he’s transitioning from a bullpen role to a starter’s workload—Boston could tilt the momentum in their favor. But it will require a clean game from the defense, six solid innings from Buehler, and for the bullpen to step up and finish the job. The Red Sox know they’re treading water in a competitive division and need series like this one to turn their season around. With Fenway’s quirks, Buehler’s upside, and the firepower to hang with anyone, Boston is fully capable of rising to the challenge—but only if they can finally synchronize their offense, pitching, and late-game execution.
