HAVANA -- A group of Cuban-born baseball stars once disdained by the island's government for defecting to the United States triumphantly returned home and on Wednesday were teaching their craft to some of their youngest fans. Los Angeles Dodgers outfielder Yasiel Puig, St. Louis Cardinals catcher Brayan Pena and first baseman Jose Abreu of the Chicago White Sox were swarmed by fans and members of the state media Tuesday in the lobby of Havana's Hotel Nacional at the start of a three-day mission meant to warm relations between MLB and Cuba.
