2010 New York Mets season

Offseason

On November 6, 2009, the Mets declined to exercise relief pitcher J. J. Putz's 2010 team option, who subsequently signed with the Chicago White Sox. Catcher Brian Schneider and shortstop Wilson Valdez signed contracts to the Philadelphia Phillies. Nelson Figueroa would also later join the Phillies on Opening Day upon being acquired off waivers from the Mets. On November 30, 2009, the Mets re-signed Alex Cora to an identical one year $2 million deal. They also signed former San Diego Padre catcher Henry Blanco and former Astro Chris Coste. In December 2009, the Mets signed pitchers Ryota Igarashi and Kelvim Escobar.

On December 29, the Mets signed outfielder Jason Bay to a four-year $65 million deal. On January 5, 2010, the Mets signed R.A. Dickey to a minor league contract. On January 13, 2010, Carlos Beltrán underwent knee surgery, and did not return until after the All-Star break. On January 22, 2010, The Mets acquired outfielder Gary Matthews, Jr. along with 21 million of the 23.5 million he was due of the last two years of his contract from the Los Angeles Angels of Anaheim in exchange for relief pitcher Brian Stokes.

The Mets signed right-handed pitcher Josh Fogg to a minor league deal on January 29, 2010, extending him an invitation to Spring training. The Mets also re-signed former member Mike Jacobs to a minor league deal and invited him to Spring training. The Mets also continued this offseason's trend of signing catchers by finalizing a deal with catcher Rod Barajas. The Mets later invited Raúl Valdés to spring training during March. He'd eventually make it on the roster in early April after Sean Green was placed on the disabled list.

On March 11, 2010, the Mets announced that starting shortstop José Reyes would miss 2–8 weeks after being diagnosed with a hyperthyroid problem, but on March 24, the Mets announced that he would return for camp that same day and would be ready for the first weekend series vs the Washington Nationals.

April

The Mets opened their season at home with a 7–1 victory over the Florida Marlins. After a shaky 4–8 start and questions surrounding the lineup, they called up highly touted prospect Ike Davis. The call-up and the surprising emergence of starting pitcher Mike Pelfrey who ended the month 4–0, with a NL leading 0.69 ERA along with the rest of the pitching staff, resulted in positive momentum for the Mets. They went 9–1 on a ten-game homestand, having done that twice in their history. They finished the homestand with an overall record of 13–9 and leading the NL East by a ½ game over the Phillies. The Mets wrapped up the month with a 9–1 win over the Phillies, giving them a 14–9 record and a 1½ game lead in the East.

May

The Mets followed their successful April by slumping to a 12–17 finish in May. However, after starting the month 6–14, the team's fortunes appeared to turn around beginning with a 5–3 victory over their crosstown rivals, the New York Yankees, on May 22. The Mets went on to win their three-game series against the Yankees, and followed it up with a three-game sweep of their NL East rivals, the first place Philadelphia Phillies. The series, in which the Mets shut the Phillies out in all three games, marked the first time the Mets had shut out a team three days in a row since 1969—when the Mets shut out the Phillies three games in a row in September. It was also only the third time since 1876 that a first place team was shut out in all games of a sweep. The Mets finished 12–17 in May and an even 26–26 overall, having gone 6–4 from May 20 onward.

June

The Mets had a strong June, continuing their winning ways at Citi Field with a nine-game home winning streak extending from May. The team finally won a series on the road, compiling a 7–2 record from June 11 to the 20th, sweeping the Baltimore Orioles and Cleveland Indians before losing two of three against the Yankees in Yankee Stadium. The Mets' resurgence was due in part to R. A. Dickey, Hisanori Takahashi and Jon Niese bolstering the starting rotation as well as José Reyes and David Wright emerging from their early season struggles to lead the team's offense. The Mets finished June 18–8, 1½ games behind the Atlanta Braves for the NL East lead and holding the NL Wild Card lead.

July and August

The Mets went into July in second place behind the Atlanta Braves. In the final series before the All-Star break, which began with the Mets just three games out of first, the Mets lost two of three to the Braves, dropping them to four games back. They never recovered, struggling for the rest of July, culminating with a 2-9 West Coast road trip, including a sweep at the hands of the last-place Arizona Diamondbacks. Their season spiraled downward further when in August, Francisco Rodriguez beat up his father-in-law in front of the other players' family. In the process, Rodriguez tore a ligament in his hand and, needing surgery, his season was ended. As a result, the Mets began the process of trying to void his contract, and placed him on the disqualified list, not paying him for the remainder of the season. In July Jason Bay suffered a concussion that he would never return from. Jeff Francoeur was traded to the Texas Rangers as August came to an end.

September and October

The season ended when Óliver Pérez earned his fifth loss of the season by hitting a batter then issuing three straight walks in the 14th inning against the Washington Nationals. The Mets lost the game 2-1.
