Nobody yet knows when it will begin and how long it will be, but for now, it's still a realistic possibility that Major League Baseball will return in 2020.

If and when it does, trade rumors will be among the many things making a swift comeback.

We thought we'd get ahead by predicting 10 trade rumors that could arise at some point during the 2020 season. The first five are strictly speculative, with the idea being to link obvious trade chips with potential suitors. The last five concern rumors that have already been heard and could come up again.

Let's take it away.    

C.J. Cron to the Philadelphia Phillies

1 OF 10

The Detroit Tigers didn't sign C.J. Cron in December just to give their woeful offense a boost.

The ongoing status of Detroit's rebuild means that Cron is also obvious trade bait. His value will be limited because he's only suited to play first base and designated hitter. But if the National League does indeed adopt the DH for 2020, Cron's bat could attract interest from both leagues.

Overall, the 30-year-old posted a .799 OPS with 55 home runs across the 2018 and 2019 seasons. He especially mashed left-handers with a .972 OPS and 19 homers.

One club that could use such a hitter is the Philadelphia Phillies. Rather than simply trusting Jay Bruce to handle everyday DH duties, they could deal for Cron and squeeze much better offense out of a Bruce-Cron timeshare. 

If the DH leaves the NL after 2020, it'll be no problem for the Phillies. Both Bruce and Cron will be free agents this winter.     

Jonathan Villar to the Chicago White Sox

2 OF 10

Like with Cron in Detroit, Jonathan Villar's time with the Miami Marlins in 2020 figures to be brief.

It's a small miracle that he's on the Marlins at all, as they were only able to pick him up because the Baltimore Orioles put him on waivers as a means of avoiding his projected $10.4 million salary.

The 29-year-old ultimately signed for only $8.2 million, which is a steal. He can play multiple defensive positions. He's also a switch-hitter who's coming off a year in which he had a .792 OPS, 24 homers and 40 stolen bases.

A player like Villar could hypothetically help any team. But if we must focus in on one in particular, the Chicago White Sox could be game.

Though the White Sox addressed many weaknesses throughout the 2019-20 offseason, they left one at second base. Villar could slot in there and in the club's leadoff spot, thereby allowing the free-swinging Tim Anderson to hit lower in the order.
