The Marlins generally are aggressive and decisive in trade discussions. But with right-hander Ricky Nolasco, they may have waited too long. Many in the industry expected Nolasco to be the first starting pitcher traded. Instead, the Cubs jumped the market Tuesday, sending righty Scott Feldman to the Orioles. Granted, the Marlins didn’t want necessarily want righties Jake Arrieta and Pedro Strop, the pitchers whom the Orioles sent to the Cubs, along with about $380,000 in international slot money, for Feldman and catcher Steve Clevenger. Sources say the Marlins are looking for prospects, not players such as Arrieta and Strop, who have struggled in the majors but possess upside. Sources also say the Marlins want their trading partner to absorb most or all of the approximately $5.7 million remaining on Nolasco’s contract.
