Not every offseason a baseball team can trade for the prior year's reigning batting champion, but that's what the Miami Marlins did when they swapped pitcher Pablo Lopez to the Minnesota Twins for Luis Arráez. After hitting .316 to top the American League, all Arráez has done in his first 50 games as a Marlin was to sport an eye-popping .371 batting average to lead all of Major League Baseball by a long shot. In April, Arráez became the first Marlins player to hit for the cycle, swatting a single, double, triple, and home run in a single game against the Philadelphia Phillies. Not too shabby at all. Already armed with undeniably strong starting pitching, the Marlins desperately needed a stellar bat in the lineup — and they got one.
