While the majority of the baseball world is focused on the stars of today and where they will be playing next season, the stars of tomorrow are honing their crafts in various offseason leagues. 

Over the next few slides, we'll rank the most eye-opening individual performances taking place in the Arizona Fall League. 

The Tampa Bay Rays have reportedly been selected as one of the participants to play in a potential spring training game in Cuba after winning a drawing by MLB commissioner Rob Manfred, according to the Tampa Bay Times' Marc Topkin. 

MLB still needs to receive clearance to hold the game in Cuba, but if all the procedural boxes are checked off, Tampa Bay will be in line to make the trip. 

Ian Desmond rejected his $15.8 million qualifying offer from the Washington Nationals, per MLB.com's William Ladson, and suitors are already starting to emerge for the free-agent shortstop.

Continue for updates.

The Boston Red Sox made an offseason splash Friday, acquiring four-time All-Star closer Craig Kimbrel from the San Diego Padres, per Ken Rosenthal of Fox Sports.

Rosenthal confirmed that outfielder Manuel Margot was part of the deal. The 21-year-old has hit .282 with 23 home runs and 175 RBI in 344 career minor league games.

Sifting through the 2015-2016 MLB free-agent market, there's just no one quite like Bartolo Colon.

Simply put, the right-hander is an ageless wonder.

Even with his 43rd birthday looming in May, Colon is still a viable free-agent option for a club that is aiming to round out its rotation. And, Colon isn't the only big league vet who proved in 2015 that his tank isn't empty just yet.

Given his history of wheeling and dealing, it was a matter of when, not if, Boston Red Sox president of baseball operations Dave Dombrowski would make his first big winter trade.

As it turns out, he didn't even wait for winter to officially begin.

After just one season with the San Diego Padres, closer Craig Kimbrel has been traded to the Boston Red Sox in a five-player deal.

The Padres confirmed Kimbrel was traded Friday to Boston for Manuel Margot, Logan Allen, Carlos Asuaje and Javier Guerra. Ken Rosenthal of Fox Sports first reported the Red Sox were acquiring Kimbrel. 

For the first time in the four-year history of Major League Baseball's qualifying-offer system, a player has accepted his team's offer, per the Associated Press (via Fox Sports).

As it turns out, $15.8 million is pretty darn enticing.

That seems like an absurdly self-evident statement. But when it comes to MLB's qualifying offer, leaving piles of money on the table has always been the name of the game—until now.

It appears San Diego Padres general manager A.J. Preller is back to his old tricks.
