The Office of the Commissioner of Baseball announced Tuesday that Cubs Minor League outfielder Adron Chambers was one of three players suspended after violating the Minor League Drug Prevention and Treatment Program.

All that matters is that the Washington Nationals ended up with a manager who is one of baseball’s most respected, decent and accomplished men of the past half century. In terms of stature, credibility and experience, Dusty Baker takes a back seat to no one.

The D-backs exercised their 2016 club options on right-handers Brad Ziegler and Josh Collmenter on Tuesday.

The Red Sox expressed confidence that Clay Buchholz is healthy, exercising the right-hander’s $13 million option for 2016.

While it appears likely that the Mariners will make a one-year, $15.8 million qualifying offer to free-agent pitcher Hisashi Iwakuma before Friday’s deadline for such bids, that decision isn’t a slam dunk.

It is no surprise, but the Phillies have declined Cliff Lee’s 2016 club option. Lee will receive a $12.5 million buyout on Nov. 30, in place of the $27.5 million contract for next season.

Unlike last offseason, when the Mets had a clear agenda — sign an outfielder, trade a starter — there is no two-dimensional path for them to take this winter. New York does need to upgrade the outfield, fill out the bullpen and make some tough decisions in the middle infield. But there are any number of ways the club can go about those things.

With the free-agent market set to open in the coming days, teams will soon tip their hands regarding their approach to the 2016 season. This winter promises to be a busy one, as there are many notable free agents and trade candidates. Here are 10 storylines that fantasy owners should closely monitor.

The Nationals officially agreed to terms on Tuesday on a multiyear deal with Dusty Baker to become the team’s sixth full-time manager.

His emotion still raw early Monday morning, David Wright forced himself to think with perspective. The Mets had just lost the World Series to the Royals, yes. But they had also turned what could have been a lost season for him, personally, and for the Mets as a ballclub into one of the most memorable in franchise history.

Now that the Royals have clinched their first World Series title in 30 years, it is time for all fans to help put a bowtie on an unbelievable October/November chase. Voting is underway through Nov. 13 at MLB.com to help determine who will be the MLB Esurance Awards winner in the category of Best Major Leaguer, Postseason.

Mickey Morandini has joined the Phillies to be their first-base coach beginning next season.

Don Mattingly was formally named manager of the Marlins on Monday morning, and he was introduced to the media during a news conference at Marlins Park.

Authoring yet another late-inning rally that resulted in yet another comeback victory, the Royals defeated the Mets, 7-2, in 12 innings to capture the World Series title, the second crown for the franchise after winning it all in 1985. Kansas City, which tied the game at 2 with two in the top of the ninth, ended the postseason having outscored the opposition 51-11 from the seventh inning on.

The Royals were kings of the comeback on their way to being crowned World Series champions, rallying to win eight games this postseason in which they trailed.

Royals GM Dayton Moore had highly complementary things to say about the Mets, a team that couldn’t have been more different from the Royals but proved to be a tough opponent in the World Series.

Christian Colon, the backup infielder for a Royals team that plays in the American League, hadn’t stepped inside the batter’s box this entire postseason. He hadn’t seen a live pitch in 28 days, and hadn’t driven in a run in six weeks. Then Royals manager Ned Yost approached Colon at the start of the 12th inning in Game 5 of the World Series from Citi Field and told him to grab a bat. He felt ready.
