2015 New York Mets season

The 2015 New York Mets season was the 54th season in the franchises' history. The Mets finished the regular season with a record of 90–72, winning the National League East title on September 26, their first division title since 2006 and sixth overall. They defeated the Los Angeles Dodgers in the NLDS in five games and swept the Chicago Cubs in the NLCS. They lost to the Kansas City Royals in five games in the 2015 World Series. It was the Mets' first appearance in the World Series since 2000 when they lost to the New York Yankees. It marked the team's first winning season since Citi Field opened in 2009 (and their first since 2008, their last season at Citi Field's predecessor, Shea Stadium).

Offseason
On November 10, 2014, the Mets signed Michael Cuddyer to a two-year $21 million deal. On December 2, 2014, the Mets officially non-tendered Eric Young Jr. On December 11, 2014, the Mets agreed to a one-year contract with John Mayberry Jr.

Spring training
During spring training, the Mets made trades for relief pitchers Jerry Blevins from the Washington Nationals and Alex Torres from the San Diego Padres.

Opening Day
On Opening Day, the Mets faced the Washington Nationals, whose starting pitcher Max Scherzer held the Mets hitless until the 6th inning. The Mets capitalized on two errors by Washington in the 6th inning: Ian Desmond committed a throwing error and Dan Uggla dropped a David Wright pop-up, and Lucas Duda finished off the rally with a two-run single into the right-center gap off a 98-MPH fastball from Scherzer. Mets starter Bartolo Colón allowed only a solo home run to Bryce Harper. After Colon left the game, Buddy Carlyle, filling in for an injured Jenrry Mejía, earned the save, giving the Mets a 3–1 victory.

April
After their opening series in Washington, former closer Jenrry Mejía was suspended 80 games for the use of stanozolol, a performance-enhancing drug (PED) banned by Major League Baseball. The Mets lost three of their first five games. After losing the first two in Atlanta to start their second series, the Mets began an 11-game win streak that started with Colón picking up his second win. The Mets then returned home, and swept the Philadelphia Phillies, Miami Marlins, and Atlanta Braves. On April 23, 2015 the New York Mets beat the Braves 6–3 to complete a perfect 10 game homestand, tying their start to the 1986 season with a 13–3 record and tying the team record with an 11-game winning streak. During the eighth game of the season, David Wright pulled his hamstring while stealing a base. He left the game and Anthony Recker was brought in to play third base. After a number of weeks, Wright was diagnosed with spinal stenosis, raising questions as to whether the captain could ever return. During the 11 game winning streak, catcher Travis d'Arnaud was hit by a pitch, leading to a wrist injury. Kevin Plawecki was called up to replace d'Arnaud. In the same game, relief pitcher Jerry Blevins was hit by a line drive, breaking his arm. Their winning streak was broken in the first game of the Subway Series, where Jacob deGrom lost to Michael Pineda. The next day, in the second game of the series, Matt Harvey pitched 8.2 innings, but after giving up back-to-back hits, Harvey was taken out of the game. He would still get the victory. No Met would pitch a complete game until September. The Mets then lost the rubber match against the Yankees, their first appearance on ESPN Sunday Night Baseball since the 2013 season.

May
In May, the Nationals took the division lead after taking three of four games from the Mets at Citi Field to start the month. Bartolo Colón saw his ERA increase to 4.80 at one point, effectively ending his All-Star chances. Noah Syndergaard was called up in mid-May and made his Major League debut on May 12 against the Chicago Cubs. He lost 6–1 in part of a four-game sweep by the Cubs at Wrigley Field. The Mets then returned home for a weekend series against the Milwaukee Brewers, winning two games to one. On Saturday, the Mets scored 14 runs, scoring 10 in the 4th inning, which included a grand slam hit by Wilmer Flores. Syndergaard picked up his first major league win on Sunday as the Mets won 5–1. In the following week, they split a four-game series with the Cardinals and were swept by the Pirates. While they started the final week of May by sweeping the Phillies, they closed the month by losing a series to the Marlins, ending May with a 28–23 record.

June
The Mets lost a series in San Diego and also split a series in Arizona. Returning home, they were no-hit by Chris Heston on June 9, which would turn out to be the first of two no-hitters thrown against the Mets in 2015. New York rebounded to win a weekend series against the Braves, and also snapped the Toronto Blue Jays' 11 game winning streak, which matched the Mets' 11-game streak as the longest winning streak of the year, by beating them on a walk-off hit by Wilmer Flores. After another win the following day, the Mets retook the division lead again. They then lost their next seven games in a row to fall back to under .500, at 36–37. Facing the Brewers, Jacob deGrom ended the losing streak by pitching 8 shutout innings to guide the Mets to a 2–0 victory and get them back to .500 returning home for a three-game set with the Cincinnati Reds.

On June 28, left-handed pitching prospect Steven Matz, a native of Stony Brook, New York and a lifelong Mets fan, made his Major League debut for the Mets against the Cincinnati Reds. He recorded four runs batted in (RBIs), breaking the Mets' franchise record for RBIs in a major league debut and setting an MLB record for most RBI by a pitcher in their debut. He went on to get the win in that game. Matz was the first pitcher from Long Island to make his MLB debut with the Mets since Ray Searage in 1981. With the win, the Mets swept the Reds to end June with a 40–38 record.

July
The Mets opened July by getting swept by the Chicago Cubs at Citi Field. In the three-game series, the Mets scored only one run. The team lost 6–1 on Thursday afternoon to drop to 40–40. After the game, local news pundits tore into the Wilpon's ownership of the team and GM Sandy Alderson not admitting there was a problem with the offense. Alderson then addressed the media and dubbed the reporters "residents of Panic City". Panic City became a popular term referring to Mets fans, especially on social media. After the sweep, the Mets went 4–2 on a road trip to the west coast in Los Angeles and San Francisco. They followed this with a sweep of the Arizona Diamondbacks at Citi Field that brought the team's record to 47–42 heading into the 2015 All Star Break. In the final game of this series, Kirk Nieuwenhuis became the tenth Met to hit three home runs in one game, and the first player in Mets history to hit three home runs in one home game; the previous nine did so on the road.

On July 29, the Mets were involved in a bizarre series of events where it was reported through various social media outlets that Wilmer Flores had been traded, along with Zack Wheeler to the Milwaukee Brewers in exchange for outfielder Carlos Gómez, as part of the Mets' desire to bring in an outfield bat. Word spread quickly around the stadium, and eventually to Flores, who took the field in the 8th inning crying and visibly emotional. After the game, general manager Sandy Alderson confirmed with the media that the trade had fallen through due to either medical concerns or disagreements on money, meaning Flores and Wheeler remained Mets. The next day, Flores was on the bench while the Mets tried to put the previous night behind them, leading the Padres 7–1 in the 7th inning. However, Derek Norris cut into the lead with a grand slam off Hansel Robles, but the newly acquired reliever Tyler Clippard sent the game into the 9th with the Mets retaining a 7–5 lead. Jeurys Familia came in to close the game, but with two outs and one strike on Norris, a heavy rainfall prompted the umpires to delay the game. After the delay, Norris blooped an 0–2 single to right field, Matt Kemp grounded a single to left field, and Justin Upton provided the final blow, homering to give the Padres an 8–7 lead, which would hold up.

Following the defeat, the Mets faced the Washington Nationals in a three-game series. The Nationals were three games ahead of the Mets, and a New York sweep could give the Mets the division lead. Prior to the first game, the Mets acquired outfielder Yoenis Céspedes, in a trade with the Tigers for minor league pitchers Michael Fulmer and Luis Cessa. That night, Flores hit a walk-off home run in the 12th inning, winning the game for the Mets by a score of 2–1. Flores had also driven in the other Mets run earlier in the game. It was also the only walk-off home run the Mets hit that season.

August
The Mets started August by sweeping the Washington Nationals and the Miami Marlins. They regained the lead in the NL East on August 3 and did not relinquish it for the rest of the season. On August 21, Céspedes became the 11th Met in franchise history and the third Met in 2015 to hit three home runs in a game when he did so against the Rockies. This feat was achieved early in the season by Lucas Duda and Kirk Nieuwenhuis.

On August 24 against the Phillies, David Wright played in his first game since April 14, having missed over four months due to a hamstring injury and a career-threatening bout of spinal stenosis. Wright hit a home run into the second deck in his first at-bat; this would be the first of eight Met home runs in the game, setting a new franchise record in their 16–7 win. The Mets also hit 45 home runs in August, setting the club record for most home runs in a calendar month.

The Mets finished the month of August with a 20–8 record, their first month with at least 20 wins since September 2000.

September
The Mets swept a three-game series in Washington against the Nationals, coming from behind in each game to do so; this sweep increased their division lead, which they would not relinquish, to seven games, effectively ending the chances of a Nationals comeback.

On September 26, the Mets clinched the National League East Division regular season championship after defeating the Cincinnati Reds 10–2.

October
The Mets were the favorites to earn a home-field advantage over the Los Angeles Dodgers in the Divisional Series, but finished 1–5 to end the season. This included being swept by the Phillies and dropping a series against the Nationals, which included a no-hitter thrown by Max Scherzer on October 3, which was the second no-hitter thrown against the Mets all season. The next day, however, the Mets won 1–0. Jacob deGrom pitched 4 shutout innings and the Mets took a combined no-hitter into the 8th, but Clint Robinson singled off Jon Niese to end the no-hitter. Curtis Granderson then homered for the only run of the game, and Jeurys Familia earned his 43rd save of the year, tying a club record previously held by Armando Benitez, who recorded 43 saves in 2001. The win also gave the Mets 90 victories, which Alderson had predicted of the team in 2014. The club ended the regular season with a record of 90–72, making it the first time since 2006 that the Mets won at least 90 games.

The Mets played the Los Angeles Dodgers in the 2015 National League Division Series, winning in five games. Second baseman Daniel Murphy hit three home runs in the series. The Mets then swept the Chicago Cubs in the 2015 National League Championship Series. Murphy was named the NLCS Most Valuable Player, after he batted .529 in the series and homered in each of the 4 games, bringing his consecutive postseason game home run streak to six games, an MLB postseason record. Murphy homered a total of seven times in the two series. The Mets would lose in five games to the Kansas City Royals in the 2015 World Series. It was the first World Series to feature two expansion teams established after 1960. Game 5 was the first game in Mets franchise history to occur in the month of November.

The 2015 World Series was the only time in the 2010s decade that a New York City team played in a World Series; the Yankees didn't reach the World Series during the decade.
