Alonso became a free agent Monday after opting out of his contract, Jon Heyman of the New York Post reports.

EDGE Analysis

Alonso wound up having to settle for a two-year, $54 million contract with the Mets last offseason, but he had the ability to opt out after the first year of that deal and has unsurprisingly done just that. The first baseman slashed .272/.347/.524 with 38 home runs and 126 RBI for the Mets in 2025. Alonso is not eligible to receive a qualifying offer this offseason, which should help his market.

Alonso is expected to exercise the opt-out clause in his contract and become a free agent this offseason, Anthony DiComo of MLB.com reports.

EDGE Analysis

Alonso signed a two-year, $54 million contract with the Mets in February, which included an opt-out after one season. The first baseman played in all 162 regular-season games for the second straight year in 2025, batting .272 with 38 home runs, 126 RBI, 87 runs scored and one stolen base over a career-high 624 at-bats. The slugger will now enter free agency with plenty of interested suitors for his talents.

Alonso went 2-for-4 with a home run, two RBI, a walk and an additional run scored in Saturday's 5-0 win over the Marlins.

EDGE Analysis

Alonso ripped his 38th big fly of the season and his seventh of the month. The All-Star first baseman will likely fall short of what could be his fourth career 40-homer year, barring a multi-homer effort in Sunday's regular-season finale in Miami, but he's once again been a prolific four-category fantasy stud in 2025. Through 161 outings, Alonso is batting a career-high .273 with 126 RBI and 87 runs scored.

Alonso went 1-for-2 with a solo home run, a walk and an additional run scored in Thursday's 6-1 win over the Padres.

He posted a .604 OPS despite three multi-hit performances during that 10-game span. Alonso is now slashing .266/.342/.510 with 72 extra-base hits and 117 RBI through 657 plate appearances.

Alonso went 2-for-5 with two solo home runs in Tuesday's 12-5 win over the Tigers.

EDGE Analysis

The first baseman racked up 823 feet worth of long balls by taking Sawyer Gipson-Long deep in the first inning and Chris Paddack in the seventh. Alonso is up to 33 homers on the season through 139 games, including five in his last 11 contests, and with 23 games left on the Mets' schedule, he's got a shot at reaching 40 for the fourth time in his career.

Alonso went 3-for-6 with a two-run homer and an additional run scored during Friday's 19-9 win over the Marlins.

Alonso has logged at least one hit in each of his last five games and has slashed .306/.342/.622 with nine homers and 29 RBI in 120 plate appearances since Aug. 1.

Alonso has hit eight of his long balls and eight of his 34 doubles over 25 games in August, batting .295 (31-for-105) this month.

Alonso went 4-for-5 with a double, two RBI and a run scored in Tuesday's 6-5 win over the Phillies.

EDGE Analysis

The four-hit game was Alonso's second of the year, with both such efforts coming in the month of August. Alonso is batting a strong .286 with seven home runs, seven doubles and 24 RBI over his last 98 at-bats as New York's top cleanup hitter. The All-Star slugger also has at least one knock in 16 of his last 23 outings.

Alonso went 3-for-5 with a double, two home runs, three RBI and three runs scored in Tuesday's 13-5 win over Atlanta.

EDGE Analysis

He's hitting .350 with six long balls, four doubles and 15 RBI across his first 40 at-bats of the month to bring his OPS to .880 for the season as a whole.
