The New York Mets saw their 2015 season end in heartbreaking fashion with a 7-2 extra-innings loss in Game 5 of the World Series on Sunday night, but even in defeat, the club showed a lot of class.

The relentless Kansas City Royals earned their second World Series title in a convincing five-game triumph over the New York Mets thanks to their own ability to come through at the plate in the late innings—and the Mets' failure to make plays when the game was on the line.

The 2015 World Series is officially in the books, as the Kansas City Royals capped off an impressive postseason run with another come-from-behind victory in Game 5 on Sunday night to claim their first title in 30 years.

There will be time to reflect on the 2015 season in the months ahead, but there is no rest for MLB teams in their pursuit of a title, and with the World Series wrapping up, the offseason is officially underway.

While the World Series spotlight shines brightest on the biggest names and most established veterans every October, less hyped and somewhat overlooked players are often the ones who come through with the most surprising moments.

The 2015 World Series was no different, with a handful of players who in some ways had become afterthoughts delivering clutch performances, some bigger than others.

From Chris Young to Mike Moustakas, plenty of unsung heroes have pushed the Kansas City Royals to the brink of winning the 2015 World Series.

With the Royals holding a 3-1 advantage over the New York Mets, this list of understated but indispensable contributors is dominated by Kansas City players.

However, there is room for one Mets veteran who made a habit of delivering in big moments during the regular season and who has been doing the exact same thing on baseball's biggest stage.

It took seven games for Kansas City to take down the St. Louis Cardinals in the 1985 World Series—the last time the Royals could call themselves world champions. Sunday night, they'll try to dispatch the New York Mets in Game 5 at Citi Field to end that 30-year wait between titles.

But don't expect the Mets to be gracious hosts.

The Kansas City Royals are one win away.

It was a classic Royals rally in the eighth inning. Thanks to hits from Mike Moustakas and Salvador Perez and an error by Daniel Murphy, the Royals scored three times in the top of the eighth and took a 3-1 series lead with a 5-3 win over the New York Mets Saturday night in Game 4 of the World Series.

The Kansas City Royals always seem to have a flair for the dramatic.

That was no different Saturday night.

Trailing 3-2 in the top of the eighth, the Royals scored three runs to take a 5-3 lead. After closer Wade Davis allowed back-to-back hits with one out in the bottom of the ninth, Lucas Duda lined out into a game-ending double play. Kansas City won 5-3 and goes into Sunday with a chance to win the World Series.

The Kansas City Royals moved to within a win of their first title in 30 years with a spoiling and late 5-3 victory over the New York Mets in Game 4 on Saturday.

The New York Mets picked up a critical win Friday night in Game 3 of the World Series to avoid the death sentence of falling behind to the Kansas City Royals 3-0 in the series.

Now it all comes down to this final week of baseball, as the Royals will look to get over the hump after coming one win away from hoisting the trophy last year, while the Mets will aim to cap off their impressive push back to contention with a title of their own.
