Diamondbacks vs Mets Highlights: Arizona’s 9th-Inning Rally Seals 6-5 Upset at Citi Field

Queens, NY—In a dramatic National League clash Tuesday night, the New York Mets edged the Arizona Diamondbacks 4-3 on Ronny Mauricio’s pinch-hit single in the bottom of the 10th inning at Citi Field. The D-backs-Mets matchup—already buzzing among early-season MLB storylines—featured stellar pitching from both rotations. Arizona starter Brandon Pfaadt scattered six hits and two runs across 6 ⅓ innings, while Mets right-hander Tylor Megill countered with five strikeouts over five frames. Slugger Ketel Marte put the Diamondbacks ahead 3-2 in the seventh with a towering solo shot to right, his third homer of the young 2026 campaign. New York answered in the eighth when Francisco Lindor lined an RBI double to the gap, tying the contest and electrifying a chilly Queens crowd of 34,782. Both bullpens then traded zeroes until the 10th, setting the stage for Mauricio’s heroics. Activated earlier in the day after a rehab stint, the highly touted switch-hitter wasted no time—sending a first-pitch fastball from Miguel Castro into left center, plating automatic runner Brett Baty for the walk-off celebration. Key takeaways for Mets fans • Mauricio’s clutch knock underscores the club’s new bench depth and could re-ignite the “Baby Mets” narrative that fueled last season’s playoff push. • Closer Edwin Díaz flashed vintage velocity, striking out two in a spotless ninth during his second outing since Tommy John surgery. • Lindor’s multi-hit game pushes his OPS to .988, silencing early concerns about his spring slump. Why this matters for the Diamondbacks Arizona, fresh off a series win in Colorado, saw its bullpen falter again—its fourth extra-inning loss since Opening Day. Manager Torey Lovullo hinted postgame that roles could shift if the late-inning leaks continue. Looking ahead The Mets (5-3) send southpaw José Quintana to the hill Wednesday night, aiming for a series sweep that would vault them atop the NL East. The Diamondbacks (4-4) counter with rookie sensation Yu-Min Lin, whose 0.75 ERA ranks among league leaders.
