The Washington Nationals acquired outfielder Adam Eaton from the Chicago White Sox in a huge trade on Wednesday, as first reported by MLB.com's Scott Merkin. 

In exchange for Eaton, the White Sox received three highly touted prospects: right-handed pitchers Lucas Giolito, Reynaldo Lopez and Dane Dunning. 

Eaton is obviously a big get for the Nationals. He comes with five years of team control, can man center field full-time and is a good bat to have at the top of the lineup. 

The Boston Red Sox have acquired left-handed starting pitcher Chris Sale from the Chicago White Sox at the Winter Meetings on Tuesday, as first reported by Ken Rosenthal of FOX Sports. 

In exchange for the ace Sale, the White Sox will recieve four prospects including infielder Yoan Moncada, right-handed pitcher Michael Kopech, outifelder Luis Alexander Basabe, and right-handed pithcer Victor Diaz. 

In addition to the Red Sox, the Washington Nationals and Atlanta Braves were two other teams to show serious interest in Sale. It was thought that the Nationals were close to acquiring him as of last night in a deal centered around Lucas Giolito. 

Today, however, Rosenthal reported that the Red Sox were still in the mix and trying to make a late run at him. Obviously, it appears that it was a successful attempt. 

The Arizona Diamondbacks have fired General Manager Dave Stewart and Manager Chip Hale on Monday, according to a team announcement.

The swift movement of Diamondbacks’ management has been expected for some time now; it was widely believed a regime change would be put in place following a dismal 2016 season.

Despite the firings of both Stewart and Hale, Diamondbacks’ Chief Baseball Officer Tony La Russa may still have a job in 2017, according to Jon Heyman of FanRag Sports and other media reports. Arizona is reportedly undecided as to whether La Russa will be a part of the team’s future plans.

The Diamondbacks promised a competitive 2016 season after the front office signed ace starting pitcher Zack Greinke to a six-year, $206.5 million deal and traded for Shelby Miller from the Atlanta Braves, among other moves. However, the team did not live up to hefty expectations, finishing 69-93, ranking fourth in the NL West.

The Shelby Miller trade, in particular, is shaping up to be one of the most lopsided trades in recent memory. The Diamondbacks’ traded former No. 1 overall pick Dansby Swanson, along with other valuable pieces, in order to get Miller, who stumbled to a 6.15 ERA in 101 innings at the big league level (Miller was actually demoted to Triple-A during the season).

There has been no word on possible replacements for Stewart and Hale, though Ray Montgomery and Phil Nevin could be fits, as Robert Murray of FanRag says.

San Diego Padres general manager A.J. Preller has been suspended without pay for 30 days for providing inaccurate medicals during trade talks, Major League Baseball announced. 

Preller's suspension specifically relates to the Padres' trade of Drew Pomeranz to the Boston Red Sox, though the Miami Marlins, Chicago White Sox and one other unnamed club reportedly complained to the league, believing that San Diego did not provide full medicals when completing trades. 

Perhaps the most notable of these incidents came with the Marlins, when right-handed starter Collin Rea exited his first game with Miami with elbow soreness. The Marlins allegedly were informed that the Padres did not provide full details on Rea, and they returned him to San Diego for highly touted right-handed pitching prospect Luis Castillo. 

According toESPN's Buster Olney, the Padres' inaccuracies with their medicals ranged just past their trades. 

Major League Baseball has a centralized injury report system known as the Sutton Medical System. Here, teams report their players' issues, varying in degree from getting some aspirin to going on the disabled list and having Tommy John surgery. 

According to Olney, most teams had approximately 60 entries in the Sutton Medical System by the All-Star Break. The Padres, rather, had fewer than 10. 

When teams are close to completing a trade, players' identifications are exchanged in the system, allowing teams to see the medical history of a player they will be acquiring to make an informed decision as to whether they are worth trading for. 

The suspension was handed down by Major League Baseball this afternoon. The Padres and Preller each released statements in response. 

From Preller:

"I accept full responsibility for issues related to the oversight of our medical administration and record keeping. I want to emphasize that there was no malicious intent on the part of me, or anyone on my staff, to conceal information or disregard MLB’s recommended guidelines. This has been a learning process for me. I will serve my punishment and look forward to being back on the job in 30 days."

From Padres Executive Chairman Ron Fowler, Managing Partner Peter Siedler and President and CEO Mike Dee:

"We accept the discipline handed down from Major League Baseball earlier today and will fully comply with Commissioner Manfred's recommendations pertaining to changes with our medical administration and record keeping. Rest assured, we will leave no stone unturned in developing comprehensive processes to remediate this unintentional, but inexcusable, occurrence. To be clear, we believe that there was no intent on the part of A.J. Preller or other members of our baseball operations staff to mislead other clubs. We are obviously disappointed that we will lose A.J.’s services for 30 days, but will work closely with him upon his reinstatement to ensure that this unfortunate set of circumstances does not happen again."

Today's suspension was not the first of its kind for Preller. 

In 2010, while the Texas Rangers' Assistant General Manager, Preller was suspended for three months for violating international signing rules. Since moving to San Diego, he again was reprimanded for conducting an international workout that is against industry regulations.

The Chicago White Sox signed first baseman Justin Morneau to a one-year contract and placed him on the 15-day disabled list, they announced on Thursday. 

The White Sox will pay Morneau $1 million, as announced. They designated Mat Latos for assignment in a corresponding move.

The 35-year-old Morneau is recovering from elbow surgery that will keep him out through midseason. 

Last year, Morneau hit .310/.363/.458 with three home runs and 15 RBIs in 182 plate appearances with the Rockies. The prior season, he won the National League batting title with a .319 average. 

When he becomes healthy, the former AL MVP (2006) will be brought in to Chicago to help add to their offense, which has been struggling this season.  

Latos, 28, signed a one-year, $3 million deal with the White Sox during the offseason, and he struggled to a 4.62 ERA in his first 11 starts, including a 7.25 ERA in his last seven outings.
