One year after Matt Williams was named National League Manager of the Year, the Washington Nationals announced Monday they've fired Williams after a disappointing 2015 season that saw the team miss the postseason with an 83-79 record:

The New York Mets are chasing an improbable and long-awaited postseason run, while the Los Angeles Dodgers have some making up to do for last year. When the 2015 National League Division Series is settled, one of the two will head home disappointed.

World Series dreams are still alive and well for 10 different postseason teams across Major League Baseball, but the rest of the league has already turned its attention toward what promises to be a busy offseason.

The bracket is set and the 10 teams have secured their places in the 2015 MLB playoffs.

This year's field has a great mix of the usual suspects—the New York Yankees, St. Louis Cardinals and Los Angeles Dodgers—and some teams making their long-awaited returns to the postseason—the Toronto Blue Jays, New York Mets, Chicago Cubs and Houston Astros.

Sunday will conclude a second straight losing season for the Boston Red Sox, but manager John Farrell's prior success is keeping him at the helm in 2016.

The Red Sox announced Farrell is returning to the dugout next year, along with bench coach Torey Lovullo and other assistants:

It's the last day of the regular season, and all 30 MLB clubs are in action.  Most of Sunday afternoon's contests are predominately meaningless and won't affect the final standings.  This has the potential to wreak havoc on DraftKings daily fantasy lineups.

However, some teams are still competing for spots in the postseason, and many players will also be looking to achieve personal statistical goals.

We made it. The end is here, and all that remains is the ever-entertaining postseason that never disappoints with its drama and intrigue.

Major League Baseball’s marathon season comes to an end Sunday. It has given us plenty of feel-good, fluffy stories as well as its fair share of controversy and ugliness. And both types were present right up until the end—the Minnesota Twins were the nice storyline, and Jonathan Papelbon gave us the despicable.

The Philadelphia Phillies are officially the worst team in baseball following Saturday’s pair of losses to the Miami Marlins. With another defeat in Sunday’s season finale, Philadelphia would post its first 100-loss season since 1969.

Hey, not sure if you've heard, but 2015 has been a pretty lousy season for the Washington Nationals.

OK, that's an understatement. More like an "epically disappointing" season. Or "colossally horrendous." Or, well, you get the idea.

As the Seattle Mariners begin to evaluate things to prepare for 2016, the fate of manager Lloyd McClendon remains up in the air with new general manager Jerry DiPoto.
