After a mostly quiet offseason, Miami made its big splash this week, agreeing to terms with free-agent lefty Wei-Yin Chen, and signing All-Star second baseman Dee Gordon to a five-year contract. The two moves increase the probability that the club is not intending to trade either Jose Fernandez or Marcell Ozuna.
