The 2016 MLB amateur draft is behind us, and all 30 major league general managers will spend the next 50 days working on trades to improve their respective team's chances of advancing to the postseason or contending in the future. This year’s trade deadline has been moved back to Aug. 1.

However, it is interesting that, as of today, there are only seven teams that are more than six games out. Historically, it has been very rare when a team that close to the postseason would become a "seller."

The National League teams that are definitely expected to be sellers include the San Diego Padres, Cincinnati Reds and Atlanta Braves. All three teams are in complete rebuild mode and their cell phones have already been burning up. The Padres are listening on everyone, including Matt Kemp, Jon Jay, Fernando Rodney, Yangervis Solarte, Melvin Upton and Derek Norris. Unfortunately, their expected two best trade pieces (Andrew Cashner and Tyson Ross) have been hampered by injuries that have eradicated their value.

The Reds are still looking to move Jay Bruce, whose value has improved from the offseason, and might even try to move second baseman Brandon Phillips one more time if he’s interested. The Braves have said in the past they’ll talk everyone on their roster except Freddie Freeman, but most baseball executives think he’ll be on the table too, along with their ace Julio Teheran. The Milwaukee Brewers, Colorado Rockies and Philadelphia Phillies are all somehow within five games of the second wild-card berth, but all three are expected to be sellers, with the Rockies as the borderline team. The Phillies could move Jeremy Hellickson, the Rockies will continue to listen on Carlos Gonzalez and will try to force someone to take Jose Reyes in the same trade, while the Brewers' best trade chip is Jonathan Lucroy -- Ryan Braun is a long shot to be traded, but he's still one of the more interesting names for teams looking for a bat. The Arizona Diamondbacks are the most interesting NL team to watch because they have several valuable trade pieces and, if they don’t start winning, they could be surprise sellers.

In the American League, only the Los Angeles Angels, Oakland Athletics and Minnesota Twins should be considered definite sellers. The Athletics have the most trade pieces to deal, led by Rich Hill, Josh Reddick and perhaps Sonny Gray if he can get healthy enough and pitch like the ace he was becoming this season, which has turned into a complete disaster for him with injury and subpar performances.

The New York Yankees are the most interesting team in the AL because they are presently over .500 and only three games out of a wild-card berth, but they also have several difference-making trade pieces in Aroldis Chapman, Andrew Miller and Carlos Beltran. Yankees general manager Brian Cashman will have to decide if it’s worth going for it this season since they’re so close or start making some deals to really improve the Yankees' chances in 2017 and beyond.

In terms of “buyers,” the Chicago Cubs have the best record and team in baseball, but that won’t stop them from adding another significant piece or two; they are committed to winning the World Series this year. A left-handed reliever is their biggest need, and they’d love to pry either Chapman or Miller away from the Yankees; Fernando Abad from the Twins or Sean Doolittle from the Athletics are other options. It also won’t surprise me if the Cubs go after one more bat, especially if it’s a one-year rental like Josh Reddick of the A's or an impact player like Jose Bautista, if the Toronto Blue Jays dropped out of the playoff picture.

Boston Red Sox president Dave Dombrowski and GM Mike Hazen are all-in trying to win another World Series in the final year of David Ortiz's career. They know they’ll need to add pitching, and they’ve had several conversations with clubs about both starting and relief pitching. Although the Red Sox are not going to trade Yoan Moncada or Andrew Benintendi, they will listen on almost all of their other prospects. They don’t want to move third baseman Rafael Devers, but they can be persuaded if they get the right big league pitcher in return.

The New York Mets have been chipping away with short-term, stop-gap, band-aid moves by acquiring the likes of James Loney from the San Diego Padres and Kelly Johnson from the Braves. But the Mets know they need another impactful bat, even though they’re hoping Lucas Duda and Travis d'Arnaud will be back in time to make a difference.

The Washington Nationals and San Francisco Giants have made it clear to other teams that they’d like to improve their bullpens before the deadline, and both are expected to fight with the Cubs for the Yankees' Chapman and Miller -- if either are ever put on the trade market. That could become a really interesting bidding war and the headline of the trade deadline if the Cubs, Nationals, Giants and maybe even the Red Sox leave the Yankees with an incredible haul for one or both of the relievers. Of course, I can never remember the Yankees “selling” and, although it would be their best move, teams are convinced they’ll go down that road. We’ll see.

The Giants are hoping Hunter Pence is back to help them at the end of the year, but with a full tear of the hamstring, there will be real questions about his impact if he does make it back this year. So not only do they need a bullpen arm, but they might need another outfield bat if Jarrett Parker and Mac Williamson don’t prove they can do it before Aug. 1. Therefore, it only makes sense that the Giants might pursue Jay Bruce of the Reds, Carlos Gonzalez of the Rockies, Reddick, Beltran or Kole Calhoun of the Angels if any of them are traded.

Don't be surprised if the Giants land Braun at the trade deadline in a blockbuster deal that would be centered on top prospects Tyler Beede and Christian Arroyo. Of course, the Brewers would have to agree to eat significant dollars in the deal that could bring another World Series to San Francisco and two impactful building blocks for the Brewers. The Giants have a long history of making deals at the deadline, and there is every reason to believe this year won’t be any different. The only question left: Will it be a reliever, bat or both?

San Francisco's archrival, the Los Angeles Dodgers, would like to add a power bat that is young and controllable but don’t want to part with their top pitching prospects to get it done. However, with a deep farm system, they’ll be an interesting team to watch if they stay in the race. They're also looking for a back-end starter. The Pittsburgh Pirates' biggest moves at this year’s deadline might just end up bringing Jameson Taillon back up to the majors and then promoting their next-best pitching prospect Tyler Glasnow. It’s unlikely they make any blockbuster trades at this year’s deadline.

The Baltimore Orioles would like to add another middle-of-the-rotation, innings-eater type starter. The Rays are looking to improve their on-base percentage to create more traffic to take advantage of their team home run power. The Kansas City Royals need another starter and bat, the Detroit Tigers need another starter and reliever, the Chicago White Sox need a left-handed bat and another set-up reliever, and the Cleveland Indians could use more power.

Contending teams like the Nationals, Mets, Cubs, Dodgers, Giants and Red Sox all appear to be aggressively prepared to make a big move between now and the deadline. They all certainly have the trade pieces in their farm system to make deals, which bodes well for the rebuilding teams they’ll be matching up with, like the Braves, Reds, Phillies, Padres, Twins and Athletics.

It should be a fun next 50 days.
