NL East
Atlanta Braves: I know Ronald Acuna Jr. has been in the big leagues for less than a year, but boy was it impressive. The Braves will probably want to see him do it over a full season first, but then they better lock up this kid quick for as long as they can.
Miami Marlins: Unfortunately for the Marlins, there isn’t much to choose from here. Lewis Brinson is their only real prospect who has been called up yet, and he did not have a great 2018. The guy above wouldn’t like this, but they could look to extend Jose Urena to secure a middle of the rotation arm for their rebuild.
New York Mets: This is something the Mets probably should have done a couple of years ago before he won a Cy Young, but they need to extend Jacob DeGrom. The ace is under control for the next two seasons and is 30-years-old. He’s already set to make $17 million through arbitration this season. The Mets should buy out his last arbitration year in 2020 and extend him another two seasons.
Philadelphia Phillies: Even though I didn’t think the Phillies gave up too much for him, it would still be wise to extend J.T. Realmuto. Otherwise, it doesn’t make a ton of sense to trade for two years of the catcher unless you think the Phillies will win a World Series during that time.
Washington Nationals: You probably thought I was going to say Juan Soto, but I’m not. Instead, I think the Washington Nationals should look to extend shortstop Trea Turner. I really love this guy, and his speed and power combination make him a dynamic player.
