The NL East has seen each team make some big splashes early on in the offseason. Well, other than the Marlins, but they at least signed two of the top international players. While it's almost a foregone conclusion that the Marlins will again finish last in the division in 2019, the other four teams have been spending the offseason making moves in order for them to challenge for the division title. Below are the main players that have been added by each team in the division thus far in the offseason.

Atlanta Braves

The surprise NL East champs last season, the Braves have brought in a former AL MVP and a former longtime Brave in the offseason.

Atlanta decided to take a one-year flier on Josh Donaldson to see if he can revert back to his former self. The 2015 AL MVP also finished fourth in voting in 2013, eighth in 2014, and sixth in 2016. After playing in 113 games in 2017, he appeared in just 52 for the Blue Jays and Indians last season.

Brian McCann was a seven-time All-Star in his nine seasons with Atlanta from 2005-2013. Turning 35 on February 20, he is coming off his worst season, as he hit just .212 with a .339 slugging percentage in 216 plate appearances with the Astros.

Washington Nationals

While the Nationals could lose one of the marquee players in the game in Bryce Harper, due to free agency, they have stocked up well to begin the offseason to try to remain a contending team even if they no longer have Harper's services.

They signed arguably the top free-agent starter on the market in Patrick Corbin. In 33 starts last season, the 29-year-old Corbin had a 3.15 ERA, 1.05 WHIP, and 246 strikeouts in 200 innings. He finished fifth in NL Cy Young voting.

After two disappointing seasons from Matt Wieters at catcher, Washington retooled behind the plate in signing Kurt Suzuki and trading for Yan Gomes.

Suzuki hit .276 with 31 home runs over the last two seasons for the Braves. Gomes was named to his first All-Star team in 2018 as he batted .266 with 16 homers for the Indians.

They bolstered their bullpen by signing Trevor Rosenthal and acquiring Kyle Barraclough. Rosenthal missed all of 2018 after undergoing Tommy John surgery, but he saved 118 games from 2014-2017 with the Cardinals.

The 28-year-old Barraclough has struck out 11.5 hitters per nine innings in his career.

Philadelphia Phillies

The Phillies received little production at shortstop in 2018, and Rhys Hoskins was a defensive liability in left field. They tried to rectify both matters by trading for Jean Segura, James Pazos, and Juan Nicasio from the Mariners in exchange for Carlos Santana and J.P. Crawford. Not only does the deal make Jean Segura become Philadelphia’s everyday shortstop, but by moving Santana, Hoskins can move to first base. CBS Sports had reported a few weeks back that the Phillies were looking to shop Santana in order to do so.

Segura was an All-Star for the second time in 2018 and hit over .300 for the third straight year.

He also has 100 doubles and 75 stolen bases since 2016. A southpaw, Pazos had a 2.88 ERA and 45 strikeouts in 50 innings. After finishing with a 2.61 ERA in 2017, Nicasio struggled mightily in 2018 with a 6.00 ERA while allowing 11.4 hits per nine innings (he did also strike out 11.4 per nine innings).

In a less notable transaction, the Phillies traded reliever Luis Garcia to the Angels who sent back Jose Alvarez according to NBC Sports. The left-handed throwing Alvarez was solid for the Angels in 2018 ending the year with a 2.71 ERA, 1.16 WHIP, and 59 strikeouts in 63 innings.

New York Mets

Much like the Phillies, the Mets haven't yet been involved in free agency this year, but they did make a blockbuster trade.

New York acquired Robinson Cano and Edwin Diaz from the Mariners in exchange for Jay Bruce, Anthony Swarzak, and three minor leaguers. The 36-year-old Cano has shown less pop in his bat (10 homers in 348 plate appearances for Seattle last season), but he did still hit .303. The eight-time All-Star was suspended for 80 games last season for violating baseball's wellness policy. There was even chatter of the Mariners trading Kyle Seager.

Diaz had 57 saves, tied for the second-most ever in a season (only behind Francisco Rodriguez's 62 in 2008). In 73.1 innings in 2018, he finished with a 1.96 ERA, 0.79 WHIP, and 124 strikeouts. Turning 25 on March 22, he was eighth in AL Cy Young voting.

Miami Marlins

The Marlins added two highly-touted Cuban brothers by outbidding others for the services of the Mesa brothers. Victor Victor Mesa will have an invite to Marlins spring training, although he is expected to start the year in the minors. The 22-year-old played for Cuba in the World Baseball Classic in 2017. His younger brother, Victor Mesa Jr., is just 17 years old.
